PERFORMANCE EVALUATION OF GROUND MOTION PREDICTION EQUATIONS FOR ABSOLUTE VELOCITY RESPONSE SPECTRA (1-10 S) IN JAPAN FOR AN EARTHQUAKE EARLY WARNING

Abstract

In our previous study¹⁾, we constructed ground motion prediction equations (GMPEs) for absolute velocity response spectra from the viewpoint of earthquake early warning of long-period ground motion intensities. In the present study, we evaluated the performance of the GMPEs for seven recent earthquakes having Mw ≥ 6.5 that occurred after the construction of the GMPEs. We found that the GMPEs generally performed well for the events. Finally, we explain a methodology for the revision of site factors in the GMPEs, and discuss some implications for future study.
