摘要
随着科技进步和工业发展,浙江省数字地震台网记录到越来越多的非天然地震事件,2015年至2021年记录到2 400余个非天然地震事件。为便于工作人员快速分析、研判地震事件性质,及时开展应急救援工作,对非天然地震事件的区域特点及识别方法的总结尤为重要。本文概述天然地震与非天然地震的波形特性,对浙江台州临海、舟山岱山、温州文成和湖州长兴4个典型区域的非天然地震波形进行震相分析、统计计算和频谱分析,并与同区域的地震波形相比较,获得浙江省非天然地震的规律与特征,归纳出浙江省不同区域的非天然地震波形特征和识别方法。
With the advancement of technology and industrial development,the Zhejiang Province Digital Seismic Network has recorded an increasing number of non-seismic events,with over 2,400 non-seismic events recorded from 2015 to 2021.It is important to summarize the characteristics and identification methods of non-seismic events to facilitate rapid analysis and judgment by earthquake workers and timely emergency response.This paper summarizes the waveform characteristics of natural and non-seismic events,analyzes and calculates the non-seismic waveforms of four typical regions in Zhejiang Province,namely Linhai in Taizhou,Daishan in Zhoushan,Wen Cheng in Wenzhou,and Changxing in Huzhou,through phase analysis,statistical calculation,and spectral analysis.The characteristics and rules of non-seismic events in Zhejiang Province are compared with seismic waveforms in the same region,and the characteristics and identification methods of non-seismic waveforms in different regions of Zhejiang Province are summarized.
