2024年中国台湾花莲海域7.3级地震对后续6级地震触发的作用分析
摘要
Abstract
On April 3,2024,a magnitude 7.3 earthquake occurred in the Hualien offshore area of China's Taiwan,and many earthquakes of magnitude 6 followed in the surrounding region within the subsequent six months.Based on a crustal velocity layered model,the co-seismic static Coulomb stress change generated by this M7.3 earthquake was calculated,and its triggering effect on the subsequent M6.0 earthquakes was analyzed.The results show that the Coulomb stress change from the Hualien M7.3 earthquake exerted a stress loading effect on the faults of several subsequent M6 earthquakes.The increases in Coulomb stress were mostly above 0.03 MPa,with some exceeding 0.3 MPa.This indicates that the occurrence of the Hualien M7.3 earthquake had a significant triggering effect on the subsequent M6.0 earthquakes in its surrounding area.关键词
