Generation of the 2022 Earthquake Swarm at Intersection of Four Geological Units at the Seismic Experimental Site, China

The abnormal variations of GPS horizontal velocity field and cross-fault baselines, seismic activity, and fluids geochemistry were found to present strong cascade and pre-, post-, and co-seismic consistency during three adjacent and successive earthquakes with a magnitude of over 6.0 that occurred at the seismic experimental site in southwest China.

在西南中国地震实验场发生的连续三次、相邻且震级超过6.0的地震过程中，GPS水平速度场的异常变化、跨断层基线、地震活动以及流体地球化学特征被发现呈现出显著的级联效应以及震前、震后以及共震的一致性。
