Fig. 3From: Improvement in the accuracy of expected seismic intensities for earthquake early warning in Japan using empirically estimated site amplification factorsRelationship between Mw and PGVobs/PGV700exp for inland crustal earthquakes of seismic intensity ≥2.5. Mw is used for M. The solid circles indicate the average of log(PGVobs/PGV700exp) at each Mw.Back to article page
