Analysis of Hypocenter Relocation by Using Double Difference Method in a Deep Underground Mining

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract Hypocenter relocation is one of the keys to success in the analysis of seismicity induction in underground mines. Overburden thickness, topography, geological complexity, and mining activities can result in newly induced seismicity that can endanger the safety of underground mine workers.

2019年6月17日四川长宁地震重定位及震源机制研究

open access: yesDizhen xuebao, 2020
采用双差重定位和W震相波形反演方法分析 “地震编目系统” 和中国地震台网中心提供的地震观测报告及区域地震波形数据,对2019年四川长宁地震序列进行了重定位,反演获取了M>4.5地震的震源机制解。地震序列重定位结果显示,长宁地震序列沿NW优势方向呈条带状分布,集中分布于5—10 km深度范围,且发震断层面呈高倾角。震源机制反演结果表明,2019年6月17日四川长宁MS6.0主震的两个可能发震断层面参数分别为:节面Ⅰ走向12°,倾角50°,滑动角139°;节面Ⅱ走向131°,倾角59°,滑动角48 ...

2022年芦山MS6.1地震:发生在隐伏反冲断层上的一次中强地震

open access: yesDizhen xuebao, 2023
继2008年汶川MS8.0地震和2013年芦山MS7.0地震后,2022年6月1日在龙门山断裂带南段又发生了一次MS6.1强震,距离2013年芦山MS7.0地震震中位置仅10 km。为研究此次地震的发震断层及两次芦山地震的关系,对震后60天的余震序列进行重定位,获得了933个高精度定位结果,EW,NS和UD方向上的定位误差分别为0.15 km,0.13 km和0.23 km。余震序列在水平分布上沿北东—南西向略长,在深度上主要分布在12—20 km,10 km以浅余震很少 ...

Earthquake Relocation Studies near Local Scale Sources using Double-Difference Technique

open access: yesRSF Conference Series: Engineering and Technology, 2021
Determination of the location of the hypocenter is very necessary to monitor the potential for seismic hazard. Positioning and seismic energy can help safety workers determine which areas can be mined or temporarily halted. Earthquakes in underground mines are caused by seismic induction due to mining activities such as blasting processes ...
