a Application of the methodology to judge the warning regions based on the observed real-time seismic intensity to M7.3 event. The warning regions, colored as red, orange, and green, respectively, denote the regions where the ground motion exceeds the first criterion value, the regions where the ground motion exceeds the second criterion value, and the regions adjacent to the red regions. b Comparison of the numbers of the warning regions, regions where seismic intensity of 3.5 or greater is estimated based on JMA EEW information and regions where real-time seismic intensity of 3.5 or larger is observed
