Characteristics and mechanisms of near-surface atmospheric electric field negative anomalies preceding the 5 September, 2022, Ms6.8 Luding earthquake, China

, 2023
Abstract. A Ms6.8 strike-slip earthquake (EQ) occurred in Luding, Sichuan province, China, on 5 September, 2022, causing great losses to the surrounding Ganzi Prefecture and Ya’an City. In this research, the near-surface atmospheric electric field (AEF), recorded at four discretely distributed sites 15d before the Luding EQ, were analyzed and ...

利用S波分裂分析2022年泸定MS6.8地震震源区上地壳各向异性

Dizhen xuebao
利用四川省地震局布设的流动台站及区域固定台网记录的2022年泸定MS6.8地震序列波形数据，进行了近震S波分裂的计算分析，研究了各台站上地壳各向异性参数的空间分布和随时间的趋势性变化特征，以及S波分裂的关键参数—快S波偏振方向和慢S波时间延迟—的时空变化。结果显示，快波偏振方向和慢波时间延迟在空间上的分布呈现明显的分区特征，并且随时间的推移表现出一定的趋势性变化，这表明上地壳各向异性不仅受控于空间位置，还受到随时间变化的应力场的影响。鲜水河断裂带上的台站L5512 ...
