| 摘 要： | 从历史地震来看,智利及其周边地区的历史强震主要集中在Nazca板块和南美洲板块之间的俯冲带上,该区也是7级以上大震频发的地区,所以对于该地区的断层结构和震源机制的研究就显得十分有必要.大地震发生后,大量余震在断层面上发生.因此余震震源位置的空间分布可以较为精确地勾画出断层面的位置.假定地震的发震断层可以用一个平面来模拟...

| Abstract: | From a historical perspective,the earthquake in Chile and its surrounding areas are mainly concentrated in the historical earthquake Nazca plate subduction plates and South America plate.So the research of strong earthquakes in the areas of fault structure and focal mechanism is very necessary.After the earthquake,large aftershocks hit at fault surface.Therefore the spatial distribution of hypocenters aftershocks could more accurately delineate the fault location.Suppose the seismogenic faults can be simula... |
