datasheet1_Geological and Geophysical Factors Constraining the Occurrence of Earthquake Precursors in Geofluids: A Review and Reinterpretation.docx

In this paper, we update the previous compilations of observed earthquake precursors from the published scientific literature of the last decade. We collected the epicentral coordinates, magnitude, hypocentral depth of each earthquake and the distance from the observed precursor and its time lag. The locations are reported and compared with data concerning geological and geophysical parameters like global seismicity, volcanic locations, heat flow and tectonic regimes. Possible relations between geological and geophysical parameters and the occurrence of fluid-related earthquake precursors are considered and discussed. Some geological and geophysical conditions can be deemed responsible for the occurrence of fluid-related earthquake precursory phenomena. Geophysical models used to explain the occurrence of earthquake precursors are discussed with the purpose of contributing to engineering proper monitoring networks. Areas of the world potentially suitable for earthquake fluid-related precursor monitoring are suggested.

本文对过去十年公开发表的科学文献中记录的地震前兆进行了更新。我们收集了每次地震的震中坐标、震级、震源深度以及从观测到的前兆到地震的距离和时间滞后。这些位置被报告并与其他地质和地球物理参数如全球地震活动、火山位置、地热流和构造体制的数据进行了比较。探讨了地质和地球物理参数与流体相关地震前兆发生之间的可能关系，并进行了讨论。一些地质和地球物理条件被认为是流体相关地震前兆现象发生的责任因素。讨论了用于解释地震前兆发生的地球物理模型，旨在为建立适当的监测网络做出贡献。建议了世界上可能适合进行地震流体相关前兆监测的区域。
