海啸地震震源机制解统计

摘要

为探索海啸地震发震时的规律，统计分析了1976-2010年的美国全球CMT地震矩心矩张量数据，并结合美国海洋与大气局的海啸灾害数据库，从海啸事件和较大海啸事件两个方面对震源机制解展开了对比统计分析，给出了海啸地震在震源方面的统计特征。%In order to find objective features of tsunamigenic source, global CMT data from 1976 to 2010 and tsunami data from NOAA are analyzed statistically, and comparative statistic analysis is conducted in the events of tsunami and bigger one. At last, some features of seismic tsunami sources are concluded.
