| Abstract: | There were a lot of quake lakes caused by 14 strong earthquakes since 26 BC in Sichuan region. Some of them are, for instance, Kangding-Luding M73/4 Earthquake in 1786, Wudu M8.0 Earthquake in 1879, Dianxi M71/2 Earthquake in 1933, Songpan-Pingwu M7.2 Earthquake in 1976 and Wenchuan M8.0 Earthquake in 2008. These earthquakes caused heavy disasters and sub-disasters to people and properties. The basic condition forming quake lakes is that the seismic intensity is equal to or greater than M6.0 and, in other w... |
