大陆内部地震尤其是浅震会对人类造成巨大的灾害,对其研究十分重要.澳大利亚大陆被认为具有典型的克拉通地壳结构,虽远离板块边界但仍呈现一定的构造活动性,是研究稳定板内块体地震活动性的理想区域.本文调研分析了澳大利亚大陆地震研究进展,发现大部分区域的震源深度很浅,有一些地震造成了地表破裂,地震活动性与新构造特征以及现今动力场背景密切相关.结合新构造和大地测量学等有效地促进了对澳大利亚地震的理解,这为我国东部板内地震研究和防震减灾提供一定的指导.
It is very important for its study that the internal earthquakes in the Mainland, especially the shallow earthquakes, will cause great disasters to human beings.Australian continent is considered as typical cratonic crustal structure, which still shows some tectonic activity far away from the plate boundary, This paper investigates and analyzes the research progress of the earthquake in mainland Australia and found that the focal depth in most of the regions is very shallow. Some of the earthquakes caused surface rupture, seismicity and neotectonics and the background of the present dynamic field Closely related to the new structure and geodesy and so effectively promote the understanding of the Australian earthquake, which provides some guidance for the study of earthquake in the eastern plate and earthquake disaster reduction.
