Analysis of non-natural seismic events and seismic characteristics in Ulanhot area
摘要
Abstract
We select non-natural seismic events and seismic data recorded by the Ulanhot Earthquake Monitoring Center Station since 2022,and study the characteristics and identification methods of non-natural seismic events based on the earthquake occurrence time,P-wave initial motion direction,amplitude attenuation characteristics,AS/AP(amplitude ratio),and spectral characteristics.The results indicate that the non-natural seismic events have obvious occurrence time pattern,high identification rate of upward P-wave initial motion direction,fast amplitude attenuation,small AS/AP ratio,and obvious low-frequency characteristics.The results can serve as an effective criterion for identifying non-natural seismic events and natural earthquakes at seismic stations.关键词
