In order to propose an empirical method for estimating Japan Meteorological Agency instrumental seismic intensity from ground motion parameters, the strong motion records during recent major earthquakes, e.g., the 2000 Tottori-ken Seibu earthquake and the 2004 Niigata-ken Chuetsu earthquake, are compiled. Using the strong motion data including relatively large number of records with high intensity level, the relationships between instrumental seismic intensity and three ground motion parameters, i.e., peak ground acceleration (PGA), peak ground velocity (PGV) and the product of PGA and PGV, are examined. Results indicate that an empirical method for estimating the instrumental seismic intensity from the parameters would predict the seismic intensity with reasonable accuracy in high intensity range.
