Associations Between Strong Earthquakes and Local Rainfall in China

Strong earthquakes are a major cause of natural disasters and may also be related to heavy rainfall events. Both phenomena have received considerable attention in seismology meteorology, two relatively independent disciplines, but we do not yet know whether there is connection between them. We investigated the characteristics daily over seismic areas China. Our statistical analyses showed that strong correlation (Ms ? 6.0) area, with 74.9% China accompanied by epicenter 86.6% area rainfall. The statistics precipitation including epicenter, was mainly light rain, only few instances torrential or storm 80% events lasting more days. maximum cumulative corresponded well occurring steep terrain, such as Taiwan central mountains eastern Tibetan Plateau. earthquake had higher frequency than 30-years climatological average dominated wet season.
