2001年下半年全球地震活动

Global Seismicity in the Latter Half of the Year 2001

20 0 1年下半年 ,全球发生 MW≥ 6.5地震 1 5次 ,其中浅源地震 1 3次 ,中源地震 2次 ;发生 MW≥ 7.0地震 6次。下半年 MW≥ 7.0地震的地震矩释放是 1 976年以来的中等水平。2 0 0 1年 1 1月 1 4日发生在中国新疆 -青海交界的 MW7.8地震 ,是下半年全球矩震级最大的地震。

During the latter half of the year 2001, there were 15 earthquakes of M W≥6 5 occurring in the world, including 13 shallow focus earthquakes, 2 intermediate focus earthquakes; 6 earthquakes of M W≥7 0 occurred in the world. The seismic moment released by the earthquakes of M W≥7 0 in the latter half of the year is of moderate level since 1976. The earthquake of M W≥7 8 occurred in the boundary between Xinjiang Uygur Autonomous Region and Qinghai Province of China on November 14, 2001 is the largest one with moment magnitude in the latter half of the year.
