摘要:

整理汇总中国地震台网发布的2022年以来全球5.0级以上地震信息,并以季度为单位对2025年1—3月的地震活动情况、地震灾害特点进行归纳总结。选取缅甸实皆7.9级、中国西藏定日6.8级地震作为本季度典型地震事件,从发震构造、灾情信息等角度展开重点分析,为相关研究提供参考。

Abstract:

This study systematically compiles and analyzes global earthquake data with magnitudes of 5.0 or above,as reported by the China Earthquake Networks Center since 2022. It provides a quarterly summary of seismic activity and earthquake-related disasters that occurred from January to March, 2025. The M7.9 Myanmar earthquake and the M6.8 Dingri earthquake in Xizang are highlighted as representative events for this period. A detailed analysis of these events is conducted,focusing on their seismogenic structures and associated disaster impacts. The findings aim to serve as a reference for further research in seismology and disaster mitigation.
