Abstract

This study applies empirical magnitude-source parameter relationships to the Mw 5.9 Lushan earthquake on June 1, 2022. By employing a hybrid source model combining a deterministic asperity model and the stochastic K2 model, 30 sets of source rupture models were generated using a truncated normal distribution method to randomly sample global and local source parameters consistent with empirical constraints. Acceleration response spectra for these 30 source models were simulated at 20 stations via the stochastic finite-fault method. The source model exhibiting the smallest residual between its response spectra and the average response spectrum was selected as the optimal source characterization for the Lushan earthquake.
