Lineament analysis as a seismic precursor: The El Mayor Cucapah earthquake of April 4, 2010 (MW7.2), Baja California, Mexico

open access: yesGeodesy and Geodynamics, 2023
An earthquake called the MW7.2 “El Mayor Cucapah” earthquake on April 4, 2010 has been analyzed for seismic precursor. The changes in the lineament system concerning its pattern and time intervals were analyzed during the earthquake preparation period ...

Earthquake Forecast via Neutrino Tomography

open access: yes, 2011
We discuss the possibility of forecasting earthquakes by means of (anti)neutrino tomography. Antineutrinos emitted from reactors are used as a probe. As the antineutrinos traverse through a region prone to earthquakes, observable variations in the matter

地震检测与震相自动拾取研究

open access: yesDizhen xuebao, 2018
针对微震事件易受噪声干扰等特点,本文将STA/LTA方法和基于方差的AIC方法(var-AIC)相结合,在震相到时初步拾取的基础上,使用台站的德洛内(Delaunay)三角剖分及台站间最大走时差约束来减少噪声干扰的影响. 利用到时进行地震定位之后,根据台站预测到时,在设定的时间窗内对地震震相进行更精细的分析. 特别是针对微震事件信噪比低的特点,设计了基于偏振分析的拾取函数,根据窗内STA/LTA方法和var-AIC方法的拾取结果自动选择合适的值作为震相到时.
