摘要

2011年3月日本仙台东部太平洋海域接连发生了MW7.5和MW9.0级地震。地震及引发的海啸给日本造成了严重的破坏。本文运用近年来国际上流行的研究大地震震源破裂过程的非反演方法,反投影远震P波,研究了这两次地震的震源破裂特征,得到了他们各自的破裂区域和破裂持续时间。
MW7.5 and MW9.0 earthquake occurred near the east coast of Japan in March,2011.The earthquake and its trigged tsunami caused the huge damage.This research apply the back projection method,which is one of the common method of study the big event,to determine the source character of these two earthquakes.
