Fig. 2From: Improvement in the accuracy of expected seismic intensities for earthquake early warning in Japan using empirically estimated site amplification factorsRelationship between fault distance and PGVobs/PGV700exp for inland crustal earthquakes of (a) seismic intensity ≥0.5 and (b) seismic intensity ≥2.5. Mw is used for M. Circles and bars show the average of log(PGVobs/PGV700exp) and its standard deviation in each distance segment, respectively.Back to article page
