From: Strong motions observed by K-NET and KiK-net during the 2016 Kumamoto earthquake sequence
Search results of the location and magnitude of the induced earthquake which give the smallest residual between the observed PGA of corresponding phase and the empirical relation by Morikawa and Fujiwara (2013). In the left panels, the values marked with red circles are the estimated distance from K-NET OIT009 station to the epicenter of the induced earthquake and the estimated moment magnitude. Right panel shows the attenuation of the observed PGA to the distance from the estimated hypocenter and the empirical relation for estimated moment magnitude denoted by the red line. Thin lines denote the range of the standard deviation of the empirical relation
