Temporal distribution of the aftershocks

(1) We did macro seismic survey to the site location

(2) We apply hypocenter relocation and moment tensor inversion by using regional permanent broadband seismic data of BMKG

(3) We perform template matching detection to search for missing foreshocks and aftershocks
