Fig. 1From: Source parameters and site amplifications estimated by generalized inversion technique: focusing on the 2018 Hokkaido Iburi-Tobu earthquakea Location map of the observation sites with the focal mechanism solution estimated by F-net, and plotting epicenter of aftershocks indicated by circle symbols. b Waveforms are all velocity of EW component. We corrected the arrival time according to JMA travel time table. c Pseudo-velocity response spectra (pSv) are shown in the figureBack to article page
