洪涝异常与云南楚雄地区强震的相关分析
Characters of precipitation variation before strong earthquakes in Chuxiong area
摘要
Abstract
Using precipitation data from 123 stations in Yunnan Province since 1960 and the method of annual precipitation anomaly percentage, we obtain the results: ① if 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;② strong earthquakes in Chuxiong area basically happened in the places where stations with annual precipitation anomaly percentage> 0.25 comparatively centralized;③ there were waterlogging abnormity before strong earthquakes in Chuxiong area, that is waterlogging-earthquake character.关键词
