美国地质勘探局地球物理学家杰西卡·特纳称,此次芦山地震是在南北走向的龙门山断裂带上发生东西反向运动造成的,是2008年的汶川地震引发的多次余震之一。但也有专家认为这是一次独立地震。中国地震台网中心主任潘怀文说,昨天发生的7级地震属于逆冲型地震,尽管破裂特征与汶川地震非常相似,但它不是汶川地震的余震。
The United States Geological Survey geophysicist Jessica Turner said, the Lushan earthquake in the Longmen mountain fault zone occurred on the North-South thing reverse movement caused, is one of the aftershocks triggered the Wenchuan earthquake of 2008. But also the expert thinks this is an independent earthquake. The China Earthquake Networks Center Director Pan Huaiwen said, yesterday's 7 magnitude earthquake belongs to thrust earthquakes, although the fracture characteristics and the Wenchuan earthquake is very similar, but it is not the aftershocks of the Wenchuan earthquake.
周本刚表示,芦山地震和汶川地震有两大相同之处,一是二者都发生在北东向展布的龙门山断裂带上,二是二者均为逆冲型地震。但二者又有所区别,从位置上看,芦山地震发生在龙门山断裂带南段,汶川地震发生在龙门山断裂带中段;从震级和烈度看,二者差别较大;从地表破裂程度看,预计芦山地震的地表破裂带长度和位移远低于汶川地震。
