华北三维虚波速度地震异常分析

Abstract

Abstract: By using 48120 digital records of 4068 earthquakes during 1993~2002 in North China region, the three dimension velocity imaging of pseudo eave is made. The significance of the change of the pseudo wave velocity imaging and the relation with seismic activity are discussed in this article. The result indicates that moderately strong earthquakes occur sometimes near the gradient belt of pseudo wave velocity, also depending on condition of geological tectonics.

Key words: Three dimension pseudo wave velocity, Imagination, Seismic activity, North China region

CLC Number:

P315.6
