USGS provided a map of Asia on May 12, 2008, which showed a total of 122 earthquakes occurring on the continent. The large red square near the center of the map depicts the Sichuan earthquake.

A USGS map shows that dozens of aftershocks occurred in a small region following the quake.

The 2008 Sichuan earthquake (simplified Chinese: 四川大地震; pinyin: Si Chuan Da Di Zhen), or "Great Sichuan Earthquake", which measured at 8.0 M_s^[8] and 8.3 M_w^[9] according to China Seismological Bureau (CSB), and 7.9 M_w according to USGS, occurred at 14:28:01.42 CST (06:28:01.42 UTC) on 12 May 2008 in Sichuan province of China. It was also known as the Wenchuan earthquake (simplified Chinese: 汶川大地震; pinyin: Wen Chuan Da Di Zhen), after the earthquake's epicenter in Wenchuan County, Sichuan province. The epicenter was 80 kilometres (50 mi) west-northwest of Chengdu, the capital of Sichuan, with a depth of 19 kilometres (12 mi).^[2] The earthquake was felt as far away as Beijing (1,500 kilometres (932 mi) away) and Shanghai (1,700 kilometres (1,056 mi) away), where office buildings swayed with the tremor.^[10] The earthquake was also felt in nearby countries.

Official figures (as of June 23, 12:00 CST) state that 69,185 are confirmed dead, including 68,636 in Sichuan province, and 374,171 injured, with 18,467 listed as missing.^[7] The earthquake left about 4.8 million people homeless,^[11] though the number could be as high as 11 million.^[12] It is the deadliest and strongest earthquake to hit China since the 1976 Tangshan earthquake, which killed at least 240,000 people. Approximately 15 million people lived in the affected area.

On May 25, a major aftershock of 6.0 M_w hit northeast of the original earthquake's epicenter, in Qingchuan County, causing eight deaths, 1000 injuries, and destroying thousands of buildings.^[13] On May 27, two more major aftershocks, a 5.2 M_w in Qingchuan County and a 5.7 M_w in Ningqiang in Shaanxi Province, led to the collapse of more than 420,000 homes and injured 63 people.^[14]

The earthquake had a magnitude of 8.0 M_s according to State Seismological Bureau of China and 7.9 M_w according to the United States Geological Survey.^[1][2] The epicenter was in Wenchuan County, Ngawa Prefecture, 80 km west/northwest of Chengdu, with its main tremor occurring at 14:28:01.42 CST (06:28:01.42 UTC), on Monday 12 May 2008.

Fifty-two major aftershocks, ranging in magnitude from 4.4 to 6.0, were recorded within 72 hours of the main quake.^[15] Preliminary rupture models of the earthquake indicated displacement of up to 9 meters along a fault approximately 240 km long by 20 km deep.^[16] The earthquake generated deformations of the surface greater than 3 meters^[17] and increased the stress (and probability of occurrence of future events) at the northeastern and southwestern ends of the fault.^[17] On May 20, USGS seismologist Tom Parsons warned that there is "high risk" of a major M>7 aftershock over the next weeks or months.^[18] Parsons actually told the New York Times that there was a "heightened" risk of large aftershocks.^[18]

Japanese seismologist Yuji Yagi said that the earthquake occurred in two stages: "The 155-mile Longmenshan Fault tore in two sections, the first one ripping about seven yards, followed by a second one that sheared four yards."^[19] Yagi's data also showed that the earthquake lasted about two minutes and released 30 times the energy of the Great Hanshin earthquake of 1995 in Japan, which killed over 6,000 people. He pointed out that the shallowness of the epicenter and the density of population greatly increased the severity of the earthquake. Teruyuki Kato, a seismologist at the University of Tokyo, said that the seismic waves of the quake traveled a long distance without losing their power because of the firmness of the terrain in central China. According to reports from Chengdu, the capital of Sichuan province, the earthquake tremors lasted for "about two or three minutes".^[20]

Places ordered by distance from epicenter (or time of propagation) :

•  China (Mainland): All regions except Xinjiang, Jilin and Heilongjiang were affected by the quake.^[21]
•  Hong Kong: Tremors were felt approximately three minutes after the quake, continuing for about half a minute. This was also the most distant earthquake known ever to be felt in Hong Kong.^[22][23][24]
•  Macau: Tremors were felt approximately three minutes after the quake.^[25]
•  Vietnam: Tremors were felt approximately five minutes after the earthquake in Northern parts of Vietnam.^[26][27]
•  Thailand: In parts of Thailand tremors were felt six minutes after the quake. Office buildings in Bangkok swayed for the next several minutes.^[28]
•  Taiwan: It took about eight minutes for the quake to reach Taiwan, then the tremors continued for one to two minutes; no damage or injuries were reported.^[29]
•  Mongolia: Tremors were felt approximately eight minutes after the earthquake in parts of Mongolia.^[23]
•  Bangladesh: Tremors were felt eight and a half minutes after the quake in all parts of Bangladesh.^[23]

According to the United States Geological Survey:^[30]

The earthquake occurred as the result of motion on a northeast striking reverse fault or thrust fault on the northwestern margin of the Sichuan Basin. The earthquake’s epicenter and focal-mechanism are consistent with it having occurred as the result of movement on the Longmenshan fault or a tectonically related fault. The earthquake reflects tectonic stresses resulting from the convergence of crustal material slowly moving from the high Tibetan Plateau, to the west, against strong crust underlying the Sichuan Basin and southeastern China.

On a continental scale, the seismicity of central and eastern Asia is a result of northward convergence of the Indian Plate against the Eurasian Plate with a velocity of about 50 mm/y. The convergence of the two plates is broadly accommodated by the uplift of the Asian highlands and by the motion of crustal material to the east away from the uplifted Tibetan Plateau. The northwestern margin of the Sichuan Basin has previously experienced destructive earthquakes. The magnitude 7.5 earthquake of August 25, 1933 killed more than 9,300 people.

According to the British Geological Survey:^[31]

The earthquake occurred 92 km northwest of the city of Chengdu in eastern Sichuan province and over 1500 km from Beijing, where it was also strongly felt. Earthquakes of this size have the potential to cause extensive damage and loss of life. The epicenter was in the mountains of the Eastern Margin of Qing-Tibet Plateau at the northwest margin of the Sichuan Basin. The earthquake occurred as a result of motion on a northeast striking thrust fault that runs along the margin of the basin. The seismicity of central and eastern Asia is caused by the northward movement of the India plate at a rate of 5 cm/year and its collision with Eurasia, resulting in the uplift of the Himalaya and Tibetan plateau and associated earthquake activity. This deformation also results in the extrusion of crustal material from the high Tibetan Plateau in the west towards the Sichuan Basin and southeastern China. China frequently suffers large and deadly earthquakes. In August 1933, the magnitude 7.5 Diexi earthquake, about 90 km northeast of today's earthquake, destroyed the town of Diexi and surrounding villages, and caused many landslides, some of which dammed the rivers.

Office buildings in Shanghai's financial district, including the Jin Mao Tower and the Hong Kong New World Tower, were evacuated.^[32] A receptionist at the Tibet Hotel in Chengdu said things were "calm" after the hotel had evacuated its guests.^[33] Meanwhile, workers at a Ford plant in Sichuan were evacuated for about 10 minutes.^[34] The Chengdu airport was shut down, and the control tower and regional radar control evacuated. One SilkAir flight was diverted and landed in nearby Kunming as a result.^[35] Cathay Pacific delayed both legs of its quadruple daily Hong Kong to London route due to this disruption in air traffic services. Chengdu airport reopened later on the evening of May 12, offering limited service as the airport began to be used as a staging area for relief operations.^[36]

Reporters in Chengdu said they saw cracks on walls of some residential buildings in the downtown areas, but no building collapsed.^[37] Many Beijing office towers were evacuated, including the building housing the media offices for the organizers of the 2008 Summer Olympics. None of the Olympic venues were damaged.^[26] Meanwhile, a cargo train carrying 13 petrol tanks derailed in Huixian County, Gansu Province, and caught on fire after the rail was distorted.^[38]

All of the highways into Wenchuan, and others throughout Sichuan province, were damaged, resulting in delayed arrival of the rescue troops.^[39][40] In Beichuan county, 80% of the buildings collapsed according to Xinhua News.^[41] In the city of Shifang, the collapse of two chemical plants led to leakage of some 80 tons of liquid ammonia, with hundreds of people reported buried.^[42] In the city of Dujiangyan, south-east of the epicentre, a whole school collapsed with 900 students buried and 50 dead. The Juyuan Middle School, where many teenagers were buried, was excavated by civilians and cranes.^[43] Dujiangyan is home of the Dujiangyan Irrigation System, an ancient water diversion project which is still in use and is a UNESCO World Heritage Site. The project's famous Fish Mouth was cracked but not severely damaged otherwise.^[44]

Both the Shanghai Stock Exchange and the Shenzhen Stock Exchange suspended trading of companies based in southwestern China. Copper rose over speculations that production in southwestern China may be affected,^[46] and oil prices dropped over speculations that demand from China will fall.^[47]

China Mobile had more than 2,300 base stations suspended due to power disruption or severe telecommunication traffic congestion. Half of the wireless communications were lost in the Sichuan province. China Unicom's service in Wenchuan and four nearby counties was cut off, with more than 700 towers suspended.^[48][49][50]

A single door frame bearing a portrait of Chairman Mao remained standing in a pile of debris.

Initially, officials were unable to contact the Wolong National Nature Reserve, home to around 280 giant pandas.^[51] However, China's Foreign Ministry later said that a group of 31 British tourists visiting the Wolong panda reserve in the quake-hit area have returned safe and uninjured to the provincial capital. Nonetheless, the well-being of an even greater number of pandas in the neighbouring panda reserves remains unknown initially. Five security guards at the reserve were killed by the earthquake.^[52] Six pandas escaped after their enclosures were damaged. By May 20, two pandas at the reserve were found to be injured, while the search continued for another two adult pandas that went missing after the quake.^[53] By 28 May 2008, one panda was still missing.^[54] The missing panda was later found dead under the rubble of an enclosure.^[55] Sadly, nine-year-old Mao Mao, a mother of five at the breeding centre, was discovered on Monday, her body crushed by a wall in her enclosure. Panda keepers and other workers placed her remains in a small wooden crate and buried her outside the breeding centre. A group of 26 Malaysian tourists including a 90-year-old woman who were intially missing after the earthquake have been found alive. None of the Malaysian tourists were injured. They are about four kilometres outside Maoxian.^[56]

The Zipingpu (紫坪铺水库) Hydropower Plant located 20 km east of the epicenter has been damaged. A recent inspection indicated that the damage was less severe than initially feared, and it remains structurally stable and safe.^[57] The Tulong reservoir upstream is in danger of collapse. About 2,000 troops have been allocated to Zipingpu, trying to release the pressure through spillway. In total, 391 dams, most of them small, were reported damaged by the quake.^[58]

China's Olympic Games organisers said that they would scale down the route of the torch through the country, and there was a minute of silence when the next leg started in the south-eastern city of Ruijin on the Wednesday after the quake.^[59]

According to Chinese state officials, the quake caused 69,181 known deaths including 68,636 in Sichuan province; 18,498 people are listed as missing, and 374,171 injured, but these figures may further increase as more reports come in.^[7] This estimate includes 158 earthquake relief workers who had been killed in landslides as they tried to repair roads.^[64]

One rescue team reported only 2,300 survivors from Yingxiu, out of a total population of about 9,000.^[65] 3,000 to 5,000 people were killed in Beichuan county, Sichuan province alone, 10,000 injured and 80% of the buildings were destroyed. Eight schools were toppled in Dujiangyan.^[66] A 56-year-old Taiwanese tourist was killed in Dujiangyan during a rescue attempt on the Lingyanshan Ropeway, where due to the earthquake 11 Taiwanese tourists had been trapped inside cable cars since May 13.^[67] A 4-year-old Taiwanese boy named Chu Shao-wei (朱紹維) was also killed in Mianzhu City when a house collapsed on him^[68] and another Taiwanese was reported missing.^[7]

Experts point out that the earthquake has hit an area that has been largely neglected and untouched by China's economic rise. Health care is poor in inland areas like Sichuan province, where the magnitude-7.9 quake struck, highlighting the widening gap between prosperous urban dwellers and struggling rural people.^[69] Vice Minister of Health Gao Qiang told reporters in Beijing on Thursday that the "public health care system in China is insufficient."^[69] The Vice Minister of Health also suggested that the government would pick up the costs of care to earthquake victims, many of whom have little or no insurance: "The government should be responsible for providing medical treatment to them," he said.^[69]

The earthquake left at least 5 million people without housing, although the number could be as high as 11 million.^[70] Millions of livestock and a significant amount of agriculture were also destroyed, including 12.5 million animals, mainly birds. In the Sichuan province a million pigs died out of 60 million in Sichuan province.^[71] Catastrophe modeling firm AIR Worldwide reported official estimates of insurers' losses at US$1 billion from the earthquake; estimated total damages exceed US$20 billion. It values Chengdu, Sichuan Province’s capital city of 4.5 million people, at around US$115 billion, with only a small portion covered by insurance.^[72]

Rain was among the many problems that occurred during the aftermath of the earthquake. Here, a group of onlookers examine a collapsed building in the rain.

Reginald DesRoches, a professor of civil and environmental engineering at Georgia Tech, pointed out that the massive damage of properties and houses in the earthquake area was because China did not create an adequate seismic design code until after the devastating Tangshan earthquake in 1976. DesRoches said: "If the buildings were older and built prior to that 1976 earthquake, chances are they weren't built for adequate earthquake forces."^[73]

News reports indicate that the poorer, rural villages were hardest hit. Swaminathan Krishnan, assistant professor of civil engineering and geophysics at the California Institute of Technology said: "the earthquake occurred in the rural part of China. Presumably, many of the buildings were just built; they were not designed, so to speak."^[73] Swaminathan Krishnan further added: "There are very strong building codes in China, which take care of earthquake issues and seismic design issues. But many of these buildings presumably were quite old and probably were not built with any regulations overseeing them."^[73]

Even with the five largest cities in Sichuan suffering only minor damage from the quake, some estimates of the economic loss run higher than US$75 billion dollars,^[74] making the earthquake one of the costliest natural disasters in Chinese history.

Sichuan "is the province most heavily used for nuclear studies and military nuclear industrial development".^[75] Several media have reported about nuclear leaks in the region as China's nuclear officials quickly check nuclear facilities residing over quake-lakes to clean up any possible messes.^[76] The Chinese government said that 32 sources of radiation have been buried, and were retrieved and later disposed by the Chinese government.^[77] The French Institute for Radiological Protection and Nuclear Safety said that none of the facilities in the region are likely to have suffered damage.^[78]

Persistent rain, as well as rock slides and a layer of mud coating on the main roads, such as the one above, hinders rescue official's efforts to enter the target region.

President Hu Jintao announced that the disaster response would be rapid.^[79] Just 90 minutes after the earthquake, Premier Wen Jiabao, who has an academic background in geomechanics, flew to the earthquake area to oversee the rescue work.^[80] Soon afterward, China's Health Ministry said that it had sent ten emergency medical teams to Wenchuan County in southwest China's Sichuan Province. On the same day, China's Chengdu Military Area Command dispatched 50,000 troops and armed police to help with disaster relief work in Wenchuan County.^[81] However, due to the rough terrain and close proximity of the quake's epicenter, the soldiers found it very difficult to get help to the rural regions of the province.^[82]

The National Disaster Relief Commission initiated a "Level II emergency contingency plan", which covers the most serious class of natural disasters. The plan rose to Level I at 22:15 CST, May 12.^[83]

An earthquake emergency relief team of 184 people (consisting of 12 people from the State Seismological Bureau, 150 from the Beijing Military Area Command, and 22 from the Armed Police General Hospital) left Beijing from Nanyuan Airport late May 12 in two military transport planes to travel to Wenchuan County.^[84]

Many rescue teams, including that of the Taipei Fire Department from Taiwan, were reported ready to join the rescue effort in Sichuan as early as Wednesday. However, the Red Cross Society of China said that (on May 13) "it was inconvenient currently due to the traffic problem to the hardest hit areas closest to the epicenter."^[85] The Red Cross Society of China also stated that the disaster areas need tents, medical supplies, drinking water and food; however it has recommended donating cash instead of other items, as it has not been possible to reach roads that were completely damaged or places that were blocked off by landslides.^[86] Landslides continuously threatened the progress of a search and rescue group of 80 men, each carrying about 40 kg of relief supplies, from a motorized infantry brigade under commander Yang Wenyao, as they tried to reach the ethnically Tibetan village of Sier at a height of 4000 m above sea level in Pingwu county. The extreme terrain conditions precluded the use of helicopter evacuation, and over 300 of the Tibetan villagers were stranded in their demolished village for five days without food and water before the rescue group finally arrived to help the injured and stranded villagers down the mountain.^[87]

Falling debris, such as the object that landed on this vehicle, hinders rescue workers' progress as they attempt to cross the mountain.

Persistent heavy rain and landslides in Wenchuan County and the nearby area badly affected rescue efforts.^[88] At the start of rescue operations on May 12, 20 helicopters were deployed for the delivery of food, water, and emergency aid, and also the evacuation of the injured and reconnaissance of quake-stricken areas. By 17:37 CST on the 13 May, a total of over 15,600 troops and militia reservists from the Chengdu Military Region have joined the rescue force in the heavily affected areas.^[89] A commander reported from Yingxiu town, Wenchuan, that around 3,000 survivors were found, while the status of the other inhabitants (around 9,000) remains unclear.^[90] The 1,300 rescuers reached the epicenter, and 300 pioneer troops reached the main town of Wenchuan at about 23:30 CST.^[91] By 12:17 CST, 14 May 2008, communication in the major town of Wenchuan is partly revived.^[92] On the afternoon of May 14, 100 paratroopers, along with relief supplies, parachuted into inaccessible Maoxian County, northeast of Wenchuan.^[93]

An elderly woman was rescued and placed on a stretcher after being trapped for over 50 hours.

By May 15, China's Premier Wen Jiabao ordered the deployment of an additional 90 helicopters, of which 60 were to be provided by the PLAAF, and 30 provided by the civil aviation industry, bringing the total of number of aircraft deployed in relief operations by the air force, army, and civil aviation to over 150, resulting in China's largest ever non-combat airlifting operation.^[94]

The Chinese Government accepted the aid of the Tzu Chi Foundation from Taiwan late on May 13. Tzu Chi was the first force from outside the People's Republic of China to join the rescue effort.^[95] China stated it would gratefully accept international help to cope with the quake.^[96][59]

A direct chartered cargo flight was made by China Airlines from Taiwan Taoyuan International Airport to Chengdu Shuangliu International Airport sending a sum of 100 tons of relief supplies donated by the Tzu Chi Foundation and the Red Cross Society of Taiwan to the affected areas. Approval from the PRC Government was sought, and the chartered flight departed Taipei at 17:00 CST, May 15 and arriving in Chengdu by 20:30 CST.^[97] A rescue team from the ROC Red Cross is also scheduled to depart Taipei on a Mandarin Airlines direct chartered flight to Chengdu at 15:00 CST on May 16.^[98]

Francis Marcus of the International Federation of the Red Cross praised China's rescue effort as "swift and very efficient" in Beijing on Tuesday. But he added the scale of the disaster was such that "we can't expect that the government can do everything and handle every aspect of the needs".^[96] The Economist noted that China reacted to the disaster "rapidly and with uncharacteristic openness", contrasting it with Myanmar's secretive response to Cyclone Nargis, which devastated that country 10 days before the earthquake.^[99]

On May 16, rescue groups from South Korea, Japan, Singapore, Russia and Taiwan arrived to join the rescue effort.^[100] The United States shared some of its satellite images of the quake-stricken areas with Chinese authorities.^[101] During the weekend, the US sent into China two U.S. Air Force C-17's carrying supplies, which included tents and generators.^[102] Xinhua reported 135,000 Chinese troops and medics are involved in the rescue effort across 58 counties and cities.

The Internet has been extensively used for passing information to aid rescue and recovery in China. For example, the official Xinhua has set up an online rescue request center in order to find the blind spots of disaster recovery.^[103] After knowing that rescue helicopters had trouble in landing into the epicenter in Wenchuan, a student proposed a landing spot online and it was chosen as the first touchdown place for the helicopters.^[104] Volunteers have also set up several websites to help store contact information for victims and evacuees.^[105] On May 31, a rescue helicopter carrying earthquake survivors and crew members crashed in fog and turbulence in Wenchuan county. None survived.^[106]

As the result of the magnitude 8.0 earthquake and the many strong aftershocks, many rivers became blocked by large landslides, which resulted in the formation of "quake lakes"; these are massive amounts of water pooling up at a very high rate behind the landslide dams which will eventually crumble under the weight of the ever-increasing water mass,^[107] potentially endangering the lives of millions of people if the water is to build up, and then break downstream. As of 27 May 2008, 34 lakes had formed in nine earthquake-affected counties due to earthquake debris blocking and damming rivers, and it is estimated that 28 of them are still of potential danger to the local people. Entire villages had to be evacuated because of the resultant flooding.^[108] These so-called "quake lakes" also pose additional hazards as the natural dams forming them are breached, causing secondary flooding.

The most precarious of these quake-lakes is the one located in the extremely difficult terrain at Tangjiashan mountain, accessible only by foot or air, in which an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company is being used to bring heavy earthmoving tractors to the affected location.^[109] This in conjunction with PLAAF Mi-17 helicopters bringing in PLA engineering corps, explosive specialists, and other personnel to join 1,200 soldiers who've already arrived on site by foot. Five tons of fuel to operate the machinery was airlifted to the site, where a sluice has been constructed to allow the safe discharge of the bottlenecked water. More than 200,000 people have been evacuated from Mianyang as of June 1 in anticipation of the dam bursting.^[110]

On May 19, 2008, people mourned for the earthquake victims at Tiananmen Square, Beijing, with the flag at half mast throughout the mourning period.

The State Council declared a three-day period of national mourning for the quake victims starting from May 19, 2008; the PRC's National Flag and Regional Flags of Hong Kong SAR and Macau SAR were raised at half mast. It is the first time that a national mourning period had been declared for something other than the death of a state leader, and many call it the biggest display of mourning since the death of Mao.^[111] At 14:28 CST on May 19, 2008, a week after the earthquake, the Chinese public held a moment of silence. People stood silent for three minutes while air defense, police and fire sirens, and the horns of vehicles, vessels and trains sounded. Cars on Beijing's roads came to a halt.^[112] The Ningbo Organizing Committee of Beijing Olympic torch relay announced that the relay would be suspended for the duration of the mourning period.^[113]

Many websites converted their front page to black and white; Sina.com and Sohu, major internet portals, limited their homepages to news items and removed all advertisements. Chinese video sharing websites youku and Tudou displayed a black background and only videos related to the earthquake were available on the homepage. The Chinese version of MSN, cn.msn.com, also displayed banners about the earthquake and the relief efforts. Other entertainment websites, including various gaming sites, were also blacked out, or had corresponding links to earthquake donations.^[114] After the moments of silence, in Tiananmen Square, crowds spontaneously burst out cheering various slogans, including "Long Live China".^[115] Casinos in Macau closed down, and servers for online computer games (such as World of Warcraft) were shut down.

All Mainland Chinese television stations, along with some Hong Kong stations, displayed their logo in grayscale, while broadcasting non-stop earthquake footage from CCTV-1. Even pay television channels, such as Channel V China, showed earthquake footage. Some TV stations suspended the broadcasting of commercials during the period.^{[citation needed]} Foreign broadcasts in expatriate communities were suspended for the days of mourning.

On the evening of May 18, CCTV-1 hosted a special four-hour program called The Giving of Love (爱的奉献), hosted by regulars from the CCTV New Year's Gala and continual coverage anchor Bai Yansong, and attended by a wide range of entertainment, literary, business and political figures from mainland China, Hong Kong, Singapore and Taiwan. Donations of the evening totalled 1.5 billion Chinese Yuan (US$208 million). Of the donations, CCTV gave the biggest corporate contribution at Y50 million.^[116]

On May 24, Hong Kong actor Jackie Chan, who donated $1.57 million to the victims, announced that he wished to make a movie about the Sichuan earthquake, saying that “I want to make a movie about the earthquake because there were so many touching stories; through this movie, we will be able to show the whole world what happened.”^[117]

Main article: Allegations of corruption in the construction of Chinese schools

This kindergarten was among the many schools in the disaster region that suffered heavy structural damage.

The Chinese government estimates that over 7,000 schoolrooms collapsed in the earthquake.^[118] Due to PRC's one-child policy, many families lost an only child when schools in the region collapsed during the earthquake. Consequently, local officials in Sichuan province have lifted the restriction for families whose only child was either killed or severely injured in the disaster.^[119] So-called "illegal children" under 18 years of age may be registered as legal replacements for their dead siblings; if the dead child was illegal, no further outstanding fines would apply. Reimbursment would not, however, be offered for fines that were already levied. Lifting of the restrictions may come as scant comfort to many, as some of the affected parents are too old to conceive again, while others have had themselves sterilized.^[119]

On May 29, Government officials began inspecting the ruins of thousands of schools that collapsed, searching for clues about why they crumbled.^[120] Thousands of parents around the province have accused local officials and builders of cutting corners in school construction, citing that after the quake other nearby buildings were little damaged.^[120] Local officials urged them not to protest but the parents demonstrated and demanded an investigation. Censors have discouraged stories of poorly-built schools from being published in the media and there has been an incident where police drove away the protestors.^[121][122] On Children's Day, June 1, 2008, many parents went to the rubbles of schools to mourn for their children. The surviving children, who were now mostly living in refugee camps performed ceremonies marking the special day but also of the earthquake.

Ye Zhiping, the principal of Sangzao Middle School in Sangzao, one of the largest in An County, is credited with proactive action that spared the lives of all 2323 pupils in attendance when the earthquake happened.^[118] During a three-year period that ended in 1999, he oversaw a major overhaul of his school. During that time he obtained more than 400,000 yuan (US$60,000) from the county education department, money used to widen and strengthen concrete pillars and the balcony railing of all four stories of his school, as well as secure its concrete floors.^[118]

AP reported that "The entire state-controlled media have almost completely ignored the issue, apparently under the instructions of the propaganda bureau. Parents and volunteers helping them who have questioned authorities about the issue have been rounded up, detained, and threatened."^[123]

However Reuters reported that Chinese prosecutors have so far joined an official inquiry into ten collapsed schools during last month's devastating earthquake to gain first-hand material of construction quality at the collapsed schools, launch preliminary inquiries and prepare for possible investigations into professional crime.^[124] It was also reported that safety checks are to be carried out at schools across China after last month's earthquake.^[125]

The New York Times reported that "government officials in Beijing and Sichuan have said they are investigating the collapses. In an acknowledgment of the weakness of building codes in the countryside, the National Development and Reform Commission said on May 27 that it had drafted an amendment to improve construction standards for primary and middle schools in rural areas. Experts are reviewing the draft, the commission said."^[126]
