选取2010—2020年呼和浩特基准地震台记录的195个6.0级以上极远震事件波形,分析震相特征。按照震中距由小到大的顺序,挑选出9个典型极远震事件作为研究对象,依据AK135走时表,分析波形记录特征,以期提高地震台站的震相分析水平及资料产出质量。
In order to analyze the characteristics of teleseismic phase recording, 195 extreme teleseismic events with magnitude larger than 6.0 recorded by Hohhot from 2010 to 2020 were chosen to study. Due to the limited space, we select 9 types of extreme teleseismic events as the research object. Considering the AK135 travel time tables, we analyze the characteristics of waveforms recorded by Hohhot stations, and aim to improve the analysis level of phase and the quality of data outputs.
