近年来全球地震与火山活动分析
|
摘要
1990年日本云仙岳火山和1991年菲律宾皮那图博火山喷发,引发了菲律宾海板块西缘的活动。全球板块运动以及相应的地震、火山活动进入一个新的阶段,特大地震活动以南半球为主,发生了2004年苏门答腊Mw9.1大震(Mw是矩震级),2010年智利Mw8.8级大地震。火山活动也有类似表现,两个VEI≥5(VEI是火山爆发指数)的喷发都发生在南半球。2011年日本仙台东发生Mw9.1级大震造成巨大的灾难,也影响了世界地震活动的格局。考虑到1933年日本三陆大震后的图像,日本弧大震可能没有完全改变全球活动格局。
The eruption of Unzen Volcano of Japan in 1900 and eruption of Pinatubo volcano of Philippine in 1991 resulted in the active in the west margin of Philippine Sea Plate,and then the global seismic and volcanism come into a new stage.Great earthquakes(M≥8)are mostly in southern hemisphere,includes Sumatra Mw9.1,2004,and Chile Mw8.8,2010.Volcano active has similar regime,both of 2 eruptions with VEI≥5 occurred in southern hemisphere.Tohoku earthquake in 2011 induced most expensive catastrophes,and effected the global seismic regime.Based on the comparison of patterns of earthquake distribution,the earthquake at Japan Arc may not overthrow the present regime of global earthquake activity.
