潮汐触发地震研究进展综述

A Reviw on Tidal Triggering of Earthquakes

对近年来国内外潮汐调制触发地震研究进行了系统综述。介绍了月相与地震活动的关系,日月引潮力及其分量对地震触发的情况,基于大样本统计的潮汐触发地震研究等内容。月相与地震活动的简单对应是对潮汐触发地震的初步研究,调制比是对这一现象的定量化描述。潮汐应力分解及对地震活动影响的研究,则是从力学的层面揭示两者之间的可能关系。大样本统计则从统计的角度研究潮汐对地震的关系,众多统计方法中应用较多的是Schuster检验,它将震源机制、潮汐应力、统计检验等因素综合考虑,定量地分析潮汐对地震的触发作用。

We systematically reviewed the study of tidal triggering of earthquakes in recent years,focusing on the relationship between phases of the moon and seismic activities,earthquakes triggered by tidal force and its components,statistics of tidal triggering of earthquake based on large sample.The relationship between phases of the moon and seismic activities is a preliminary study of tidal triggering of earthquakes,and the modulation ration is a quantitative description of it.Using decomposition of tidal stress to study seismic activities is a way to reveal the relation between the tides and earthquakes from mechanics.Large sample statistics is another way to study the relation between the tides and earthquakes from the view of statistics.In many statistical methods,Schuster′s test is used more widely,which takes into account many factors such as focal mechanism,tidal stress,statistic test to quantitatively analyse the impact of tidal triggering of earthquakes.
