| 英文摘要 | The 2008 Wenchuan earthquake (Ms=8.0; epicenter located at 31.0 degrees N, 103.4 degrees E), with a focal depth of 19.0 km was triggered by the reactivation of the Longmenshan fault in Wenchuan County, Sichuan Province, China on 12 May 2008. This earthquake directly caused more than 15,000 geohazards in the form of landslides, rockfalls, and debris flows which resulted in about 20,000 deaths. It also caused more than 10,000 potential geohazards sites. It has been two years after the Wenchuan earthquake taking place in 12 May, 2008. Researchers are still concerned about what happens to the geohazards which were triggered by the earthquake during the rain season in these years. By field investigation and statistical analysis in Chengdu City, the distribution of landslides triggered by the earthquake was analyzed and the correlation analysis between rainfall and seismic landslides were conducted in the extremely earthquake stricken region around the Longmenshan mountain region. The regional distribution of geohazards follow the 2 linear law with the macro-epicenter, large scale geohazards are located within 14.9 km from the macro-epicenter, moderate and small scale geohazards within 52.7 km from the macro-epicenter. And a large amount of geohazards was triggered by the Wenchuan earthquake which reached the historical peak in numbers. Since then the rainfall has become a major triggering factor of landslide occurrence in the earthquake hit regions and the geohazards will be much more vulnerable to rainfall and substantial in the future decade. |
