DOI: 10.1002/2017jb015077
Abstract: The 2016 M_w 6.2 Tottori earthquake occurred on 21 October 2016 and produced thousands of aftershocks. Here we analyze high-resolution-relocated seismicity together with source properties of the mainshock to better understand the rupture process and… read more here.
