CHARACTERIZED SOURCE MODEL OF THE 2024 NOTO PENINSULA EARTHQUAKE USING EMPIRICAL GREEN’S FUNCTION METHOD

The characterized source model (0.2–10 Hz) composed of strong motion generation areas (SMGAs) of the 2024 MJ7.6 Noto Peninsula earthquake was estimated using the empirical Green’s function method introducing the simulated annealing method. All nine SMGAs were located deeper than 4 km from the surface. The SMGA with the largest short-period spectral level A was located on the northeastern fault with the opposite dip direction from the other faults. The A of total SMGAs was slightly larger than the previous scaling models and four Mw ≧ 7.4 crustal earthquakes outside Japan.
