About characteristics of seismicity anomalies before JingguM 6.6 earthquake in Yunnan Province, 2014
摘要
Abstract
The JingguM 6.6 earthquake occurred on October 7, 2014 in Yunnan Province. Before the earthquake, there are the quiet ofM≥6.0 earthquakes for up to 7.3 years and the quiet of M≥6.0 earthquakes for up to 2 536 days in Southwest Yunnan. But there are different that theM4.0—4.9 earthquakes increased notably since 2013 in Sipu area. Jinggu earthquake occurred in the background gaps formed byM4.0—4.9 earthquakes, there is the preparatory gaps formed byM3.0—4.9 earthquakes in short time too. AnM 3.5 earthquake occurred at 05:36 on October 7,2014. It occurred on the edges of preparatory gaps. We called it “imminent earthquakes”. The research shows that the seismicity indicates the dynamic characteristics of long,medium and short term seismic anomalies before this earthquake.关键词
