对于地震成因,地质学上一般是这样解释的:岩石圈中的板块在软流圈上漂移的过程中,互相挤压、碰撞,积蓄能量,当这种能量积蓄到一定程度,超过了岩石强度,就会使地壳破碎、错动,从而产生地震。不久前,美国加州地层研究学院的一位科学家提出地球表层经常出现的强大风力,可能是诱发地震的重要动力之一。在1986年9月及1987年10月,加州南部地区先后发生过几次4.5级的中度地震。这几次地震发生前,这位科学家对该地区风力变化情况进行了详细的监察及记录。他发现,每当地震发生前的4至6个星期内,
For the cause of the earthquake, geology generally explains this: plates in the lithosphere are squeezed and collide with each other and accumulate energy as they drift over the asthenosphere. When this energy accumulates to a certain extent and exceeds the rock strength , It will crush the Earth’s crust, staggering, resulting in earthquakes. Not long ago, a scientist at the California Institute of Stratigraphic Research proposed that the strong winds often appearing on the earth’s surface may be one of the major motivations for the earthquake. In September 1986 and October 1987, several moderate earthquakes of magnitude 4.5 occurred in southern California. Before these earthquakes, the scientist conducted a detailed inspection and record of the wind changes in the area. He found that within four to six weeks before the earthquake,
