Fig. 9From: Improvement in the accuracy of expected seismic intensities for earthquake early warning in Japan using empirically estimated site amplification factorsRelationship between distance from seismic intensity stations to the Japan and Kuril trench axes and PGVobs/PGV700exp for earthquakes deeper than 30 km in northeastern Japan (a) before and (b) after application of correction term H for abnormal seismic intensity distribution to PGV700exp. Mw is used for M. Solid triangles indicate the location of the volcanic front.Back to article page
