Aftershock sequence of the 2017 M w 6.5 Jiuzhaigou, China earthquake monitored by an AsA network and its implication to fault structures and strength

We deployed a seismic network near the source region of the 2017 Mw 6.5 Jiuzhaigou earthquake to monitor aftershock activity and to investigate the local fault structure. An aftershock deployment of Array of small Arrays (AsA) and a Geometric Mean Envelop (GME) algorithm are adopted to enhance detection performance. We also adopt a set of association, relocation and matched-filter techn...
