The variations of apparent stress before and after Menyuan MS 6.4 earthquake in 2016
摘要
Abstract
Based on waveform date observed by the regional seismic netwok of Qinghai Province, we calculated source parameters of 184 ML ≥ 2.5 earthquakes occurred in research area from 2010 to 2016 and 150 ML ≥ 2.0 Menyuan aftershocks in 2016, analyzed temporal-spatial variations of apparent stress. The results show there is a positive correlation between apparent stress and magnitude. which increases with the increase of magnitude; The apparent stress of medium-small earthquakes before Menyuan M 6.4 earthquake change obviously. It may reflect the enhancement of regional stress field. The apparent stress showed significant increase before Menyuan ML5.0 earthquakes.关键词
