高温高压下矿物流变强度与深源地震机制
Deep seated earthquakes, often severe in magnitude, generally occur beneath subduction zones, as one plate is forced deep into the mantle beneath another.
当一个板块被迫深人另一个板块下面的地幔中时，强烈的深源地震一般会发生在俯冲带的下部。
Focal depth estimation of the 2005 M_S5.1 Lindian,Heilongjiang of China,earthquake
2005年林甸M_S5.1地震的震源深度
It was a relatively shallow one, only 10.4 km deep.
这次地震的震源相当浅，深度只有十点四公里。
It occurred at a depth of 54.2 km.
震源则是在五十四点二公里深的地底。
Depths of these hypocenters concentrate at about 12km deep in the upper crust.
这些震源深度集中在地壳上部约12公里处。
