- BROADBAND SOURCE MODEL OF THE 2022 OFF FUKUSHIMA PREFECTURE EARTHQUAKE BY BACK-PROJECTION AND EMPIRICAL GREEN’S FUNCTION METHODS
抄録
<p>The author has estimated a broadband source model of the 2022 off Fukushima prefecture earthquake (MJ 7.4) by the back-projection and the empirical Green’s function methods using S-net, K-NET and KiK-net records. Five strong motion generation areas (SMGAs) do not overlap the aftershock area. Two SMGAs are located at shallow area in oceanic crust and the other three SMGAs are located at deep area in oceanic mantle. The two SMGAs at shallow area contribute largely to strong motions at land. The short period spectral level is larger than the previous equations for intraslab earthquakes.</p>
