| 摘 要： | 水对地震的作用(例如水库地震、注水地震乃至河流泛滥、大型灌溉诱发地震等现象)已为人们所注意和研究.本文提供并讨论了许多大气降水影响地震活动性的事例.初步研究表明,大气降水对某些地区的浅源地震活动有着某种调制作用,这可能是降水变率影响不均匀地壳的应力调整所致.

| 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. |
