摘要: 强震孕震阶段, 构造板块及断裂带内部发生的地球物理、 地球化学变化可通过介质的传播到达地表及大气层, 并最终以电磁波的形式被卫星传感器所接收。 近30年来, 人们利用卫星观测数据提取并分析了许多陆地地震前的地球物理和地球化学场异常信息, 但对海洋地震前的异常现象研究较少。 文章结合CiteSpace可视化分析法, 通过全面梳理国内外文献对海洋地震异常的观测结果, 对与海洋及近海地震相关的不同参量变化特征及海-气耦合关系进行了总结, 探讨了现阶段制约遥感技术在海洋/近海地震研究领域应用成效的关键问题, 最后结合目前研究中存在的问题与挑战, 对海洋地震异常遥感监测领域的发展趋势进行了展望, 为构建包括海洋在内的地震多圈层耦合模型提供了重要支撑。

Abstract: During the seismogenic stage of a strong earthquake, the geophysical and geochemical changes in the tectonic plate and fault zone can propagate to the earth's surface and atmosphere through the medium, which can be observed by sensors aboard on satellite in the form of electromagnetic waves. During the past three decades, many geophysical and geochemical anomalies before continental earthquakes have been extracted and analyzed using satellite data. But less studies have been conducted on coastal earthquakes. Combined with the visualization analysis provided by the software named CiteSpace, the present paper comprehensively reviews the anomalies associated with coastal earthquakes based on remote sensing observation. By summarizing the variation characteristics of oceanic and atmospheric parameters related to coastal earthquakes, we discussed the key issues restricting the application of remote sensing technology in the research related to coastal earthquakes anomalies at present. Finally, combined with the analysis of problems and challenges in this field, the trend of coastal anomalies observation using remote sensing data is prospected, which provides an important support for the construction of comprehensive seismic multi-geosphere coupling model that includes both continental and oceanic earthquakes.
