Earthquakes
There were two shocks with magnitudes exceeding 5, and they constituted an earthquake doublet.
The two largest tremors were reported to be the major events in a sequence that included over 60 aftershocks. In addition to Yunnan and Guizhou, the shaking could be felt in Sichuan and Chongqing.
Effects
The quakes caused landslides that blocked roads in the area of the hardest hit region, the town of Luozehe (洛泽河) in Yunnan Province, as well as cutting off utilities and communications. The affected areas are densely populated and mountainous.
81 people were killed, more than 800 people were injured, and more than 6,600 houses were flattened, while many thousands more were damaged. In neighbouring Guizhou Province, collapsed houses were reported in Weining County, and houses were damaged in Hezhang County. 30,265 households were left without power; 28,158 were restored by midday on 9 September 2012. Telecommunication in the affected area was restored roughly to the state before the earthquake by midday on 9 September 2012. Direct economic losses were estimated at 3.5 billion yuan (US$552 million).
In Zhaotong, 96 highways were cut off by the earthquake. According to the Communications Bureau of Zhaotong Prefecture, frequent aftershocks and landslides could cut off restored road access.
Premier Wen Jiabao flew to Yiliang and spoke to victims of the earthquakes. He also visited hospitals and tent settlements set up for the displaced.
Relief efforts
The Red Cross has sent jackets, quilts, tents, rice, and cooking oil to the affected area. Sichuan Province sent medical personnel and ambulances to Yunnan for support. The central government of China allocated a fund of 1.05 billion yuan (US$165 million) on 8 September 2012 for relief and reconstruction.
