【摘要】 利用云南省123个气象台站1960年以来的降雨量资料,使用年降雨量距平百分率方法,分析楚雄强震与降雨量的关系,结果发现:年降雨量距平百分率≥0.25的台站数大于8,次年云南地区皆有Ms≥6.0地震,也是楚雄地区发生6级强震背景条件;楚雄地区强震前表现涝异常,即该区域强震具有涝—震特征。更多还原

【Abstract】 Using precipitation data from 123 stations in Yunnan Province since 1960 and the method of annual precipitation anomaly percentage,we obtain the results:①if there were more than 8 stations with annual precipitation anomaly percentage> 0.25,earthquakes with M≥6.0 would happen in Yunnan region,which is also the background condition that earthquakes with M≥6.0 would happen in Chuxiong area;②strong earthquakes in Chuxiong area basically happened in the places where stations with annual precipitation anomaly percentage> 0.25 comparatively centralized;③there were waterlogging abnormity before strong earthquakes in Chuxiong area,that is waterlogging-earthquake character.更多还原
