| 摘 要： | 波形相关意义的“重复地震”在自然界中普遍存在，其数量远远超过我们的预期。近年来由于数字地震观测技术的普及和发展，有关“重复地震”的研究引起越来越多的关注，目前“重复地震”研究已被广泛应用于检测地壳介质性质变化、评估地震台网的定位精度、估计地震“复发”的概率和断层深部滑动速率的估算方面的估计；在提高定位和震相识别精度、断层结构、震源物理及地震预测研究等方面也都显示出值得关注的应用潜力。本文对有关“重复地震”的最新研究及应用成果进行了总结和归纳。

| Abstract: | "Repeating earthquakes",identified by cross-correlation of seismic waveforms,are found to be much more abundant in the nature than conventionally expected. In recent years, with the development of digital seismic networks, waveform cross correlation and "repeating earthquakes"have caused much attention to the measuring the variation of crustal medium properties and estimation of location accuracy and fault slip rate at depth or earthquake recurrence intervals. Moreover, as a useful tool, the "repeating earthquake" approach has also been used in the assessment of the accuracy of seismic phase picking,hypocenter location,fault structure and physics of earthquake sources,as well as the study of earthquake prediction. In this paper, we summarized the latest research and applications of "repeating earthquakes". |
