Physics-Based Ground-Motion Simulations of the 2023 Mw 6.0 Jishishan Earthquake: Reproducing the Observed Macroseismic Intensity Using Broadband Hybrid Source Models
The 2023 Mw 6.0 Jishishan earthquake in China caused severe damage and fatalities. Waveform analyses indicate that using a 1 Hz cutoff frequency underestimates broadband ground motions by about 70% for peak ground velocity (PGV) and up to 90% for peak ground acceleration. Physics-based simulations up to 3.5 Hz using...
