摘　　要：Although earthquake lights have been known since ancient times,it has not been easy to study them.It was not until the 60s that the first photographs of them were taken.During the Peruvian earthquake in 2007,it was possible to obtain the fi rst fi lm recording on earthquake lights.Likewise,during the earthquakes in Ecuador in 2016 and in Mexico in 2017,two fi lms of the earthquake lights were recorded.These fi lm recordings have helped in the study of earthquake lights,both for their objectivity and for their informational content.Several causal mechanisms have been proposed to explain earthquake lights:piezoelectricity,radon emanation,fluid diffusion,friction-vaporization,positive holes and dipole currents,among others.In this work a time difference correlation between earthquake lights and seismic ground accelerations was found and we use both seismic data and fi lm recordings of earthquake lights to explain its origin.In the discussion section it is suggested that fracturing of rocks manifest itself to some extent in the form of static electricity producing earthquake lights through induction The induction model proposed is new and it can explain the formation of EQL,even if the earth’s crust has layers of large electrical resistivity.The model also explains the formation of seismic lights without the need for special conditions on the earth’s surface or in the atmosphere.A better understanding of the earthquake lights generation process can improve our understanding of seismicity and help in the prediction of earthquakes.虽然自古以来就知道地震光,但直到60年代,才拍摄下第一张地震光照片。在2007年在秘鲁发生地震期间,录下了第一部地震光录像。同样,在2016年瓜多尔地震和2017年墨西哥地震期间,记录了两部地震光电影。这些电影记录,无论是客观还是信息内容,都有助于研究地震光。已经提出了几种解释地震光的因果机制:压电性、氡放射、流体扩散、摩擦汽化、正极洞穴和偶极电流等等。在这项工作中,我们发现了地震光和地震地面加速度之间的时间差相关性,并使用地震数据和地震光的胶片记录来解释其起源。在讨论部分,建议岩石破裂在某种程度上表现为通过感应产生静电的地震光。我们建立了一个新的感应模型,可以用于解释EQL的形成,即使地壳具有大电阻率层。该模型还解释了地震光的形成,而不需要地球表面或大气中的特殊条件。更好地理解地震光的生成过程可以提高我们对地震活动的理解,并有助于预测地震。
