论文摘要
长期以来，全世界发生的大地震已被认为是分布的非泊松，因此涉及一些大规模相关机制，这些机制可能是地球内部或外部的。到目前为止，尚未证明全球地震性与一种可能的机制的统计学显着相关性。在本文中，我们分析了ISC-GEM目录报告的20年质子密度和速度数据。我们发现质子密度与大地震发生之间的明显相关性（M> 5.8），一天的时间转移。这种相关性的意义非常高，概率是不到10-5。相关性随地震目录的幅度阈值而增加。还提出了一个暂定的模型，该模型是根据施加的电场引起的反向压电效应的。该结果在地震解释以及地震预测中开辟了新的观点。
Large earthquakes occurring worldwide have long been recognised to be non Poisson distributed, so involving some large scale correlation mechanism, which could be internal or external to the Earth. Till now, no statistically significant correlation of the global seismicity with one of the possible mechanisms has been demonstrated yet. In this paper, we analyse 20 years of proton density and velocity data, as reported by the ISC-GEM catalogue. We found clear correlation between proton density and the occurrence of large earthquakes (M>5.8), with a time shift of one day. The significance of such correlation is very high, with probability to be wrong less than 10-5. The correlation increases with the magnitude threshold of the seismic catalogue. A tentative model explaining such a correlation is also proposed, in terms of the reverse piezoelectric effect induced by the applied electric field. This result opens new perspectives in seismological interpretations, as well as in earthquake forecast.
