A PRELIMINARY STUDY OF THE MODULATION ACTION OF ATMOSPHERIC PRECIPITATION ON SEISMIC ACTIVITY

LI HAIHUA, XIE FENGLAN

Abstract

It has been noted that water induces seismicity. For example, reservoir pounding, water injection, waterflood and large scale irrigation have induced seismicity.In this paper, we discussed many facts relating to the influence on seismic activity by the change of atmospheric precipitation. Preliminary result seems to show that modulation action of atmospheric precipitation does affect the occurrence of shallow focus earthquakes in certain regions. It is probably caused by the influence of the change of the rate of precipitation upon the stress adjustment of the inhomo-geneous crust.
