Abstract

Large earthquakes can cause both casualties and economic losses, but they also provide invaluable opportunities for earthquake scientific research. Geofluids, due to their wide distribution, sensitive response to underground conditions, and ease of observation, are widely applied in field investigations after earthquakes. Analyzing the origin of fluids, energy transfer processes, temperature/pressure conditions, and the spatial-temporal evolution of geofluids can provide valuable information concerning the mechanism of earthquake precursor anomalies, short-term prediction methods, identification of the seismogenic faults, determination of earthquake risk, and the environmental impact of post-earthquake fluids. This article details post-earthquake scientific expeditions and research on fluid geochemistry in China and abroad, aimed at providing ideas and guidance for future scientific expedition work and geochemistry-related earthquake studies.

地震地球化学科学考察和研究

大地震会造成人员伤亡和经济损失，但同时也为地震科学研究提供了宝贵的机会。地质流体分布广泛，对地下条件反应灵敏，易于观测，因此被广泛应用于地震后的现场调查。分析流体的起源、能量传递过程、温度/压力条件以及地质流体的时空演化，可以为地震前兆异常的机理、短期预测方法、成震断层的识别、地震风险的确定以及震后流体对环境的影响提供有价值的信息。本文详细介绍了国内外震后科学考察和流体地球化学研究情况，旨在为今后的科学考察工作和与地球化学相关的地震研究提供思路和指导。
