The Lushan earthquake or Ya'an earthquake (Tibetan: Yak-ngai Sayom གཡག་རྔ་ཡི་ས་ཡོམ་) occurred at 08:02 Beijing Time (00:02 UTC) on April 20, 2013. The epicenter was located in Lushan County, Ya'an, Sichuan, about 116 km (72 mi) from Chengdu along the Longmenshan Fault in the same province heavily impacted by the 2008 Sichuan earthquake. The magnitude of the earthquake was placed at Ms 7.0 by China Earthquake Data Center, Ms 7.0 by Russian Academy of Sciences, Mw 7.0 by Geoscience Australia, Mw 6.6 by the United States Geological Survey (USGS), Mw 6.6 by the European Alert System (EMSC) and Mj 6.9 by the Japan Meteorological Agency (JMA). 1,815 aftershocks have been recorded as of 00:00 (UTC+8h) April 22.
The earthquake has resulted in 196 people dead, 24 missing, at least 11,826 injured with more than 968 seriously injured as of 5:00 PM (UTC+8h, April 20). Sichuan provincial government has held the 3rd press conference on April 21, reported that the earthquake has resulted in 186 people dead, 21 missing, 11248 injured and 852 of them seriously as of 2:00 PM (UTC+8h, April 21), this is still the latest official report. Several townships suffered major damage, and many old buildings in Lushan collapsed. The electricity service was interrupted, and the electricity grids in the counties of Baoxing, Lushan, and Tianquan disintegrated. Telecommunication was interrupted in part of Ya'an. The Chengdu–Ya'an and Ya'an–Xichang sections of the G5 Beijing–Kunming Expressway were reserved exclusively for vehicles for rescue purpose and closed to other vehicles. The Xiaojin section (小金段) of Sichuan Provincial Highway 210 between Baoshan (宝山) and Lushan was interrupted. A debris dam appeared in Jinjixia (金鸡峡) of the Yuxi River (玉溪河) in Lushan. 2 volunteers were injured seriously in a traffic accident on the way to Lushan. However, around 60 giant pandas in the BiFengXia National Nature Reserve in Ya'an, were left unharmed by the devastating earthquake.
The epicenter was located in Lushan. As of April 21, it was reported that 120 people died, 578 people were seriously injured, 5537 slightly injured, 278 saved from the ruins, and 3 still missing in Lushan County. The electricity grid disintegrated, and there were no water and gas services. According to China News Service, "100%" of houses in the 9 towns and townships and in the county seat were damaged.
As of April 21, it was reported that 24 people died, 2500 were injured, and 19 missing in Baoxing County. The electricity, water, and gas services were interrupted in the county seat. Most of houses in the county seat of Baoxing were uninhabitable. Water, medicines, and tents were urgently needed. Some rescuers had had to walk to Baoxing because major roads to there were cut off. On April 22, it was reported that the access to the county seat of Baoxing had been restored.
About 8,000 soldiers from the People's Liberation Army were sent into the stricken area in the immediate aftermath of the earthquake, as well as 1,400 provincial rescue workers and 120 support vehicles. Also, 180 doctors from a Chinese emergency response team and search-and-rescue dogs were dispatched, with volunteers mobilized from other parts of the country.
Chinese Premier Li Keqiang toured the area and emphasized the need for quick action. Officials warned that regional rainfall and aftershocks were factors complicating the rescue efforts, with potential secondary effects like additional landslides and further building collapses being concerns. Impassible roads and damaged communications infrastructure posed substantial challenges to rescue efforts.
To fund relief efforts, the One Foundation asked for donations, also beginning to accept donations in the virtual currency Bitcoin, in which it received an amount of $30,000 USD within a few days.
Hong Kong chief executive, Leung Chun-ying, put forward a proposal to the Legislative Council to donate HK$100m ($13m) to the Sichuan provincial government for relief efforts. However, the government motion was vehemently opposed by legislators, in particular pan democrats, who feared that the local government would misuse the funds destined to help with earthquake relief efforts. Apparent signs of misappropriations or misuse by local officials of $HK9 billion donated after the earthquake in 2008 was cited as one major concern. The proposal failed to win support of Hong Kong people. An civic campaign was started online to try to stop earthquake donations falling into the hands of corrupt officials; and the liberal Apple Daily highlighted embezzlement scandals on the mainland. To satisfy the legislature, the Hong Kong government was forced to donate the money to registered Hong Kong non-governmental organisations.
On April 25, the provincial government of Sichuan announced that April 27 (seven days after the occurrence of Lushan earthquake) would be the day of mourning for those that passed in earthquake. Public entertainment was forbidden, and the sound of siren wailed for 3 minutes to mourn the loss of earthquake. The domestic media also mourned the passed in different ways. Baidu changed its background of the page to black. The social media also developed a special feature about the Lushan earthquake.
