近年来,随着我国科学技术不断发展,噪声成像方法原理的发展越来越成熟,已经成为众多学者的关注焦点,并广泛应用与地震预测研究领域中。噪声成像是利用两个台站之间记录到的长时间连续背景噪音进行互相关计算可以提取出台站间的经验格林函数,然后利用层析成像的方法得到不同时段地球内部的速度结构,根据速度结构分析强震枪后的波动速度,从而以此来对地震进行预测研究。本文将对噪声成像在地震预测研究中的应用现状进行分析,并探讨其未来的发展方向。
In recent years, with the continuous development of science and technology in our country, the development of noise imaging method principle has become more and more mature, which has become the focus of many scholars and widely used in the field of earthquake prediction research. Noise imaging is the use of long-term continuous background noise recorded between two stations for cross-correlation calculation can be extracted from the station Greenland function, and then use tomography method to get different time intervals within the Earth’s velocity structure, according to the speed The structure analysis of the wave velocity after the strong earthquake gun, in order to predict the earthquake. This article will analyze the application status of noise imaging in earthquake prediction research and discuss its future development direction.
