Abstract:

The collapse, landslide and mud-rock flow in Shandong have the following characteristics as concentrated distribution, long-time last, multi-kinds, small scale and great loss. According to factual information, their space-time distribution characteristics are analysed by statistics and standard denseness method; according to geographic and geological backgrounds, their multi-occurring places are predicated; according to meteorological period and earthquake activity rule, their multi-occurring period which i...
