Predicted shaking intensity varies with velocity model choice during the 2022 Luding earthquake

Caption

Simulated seismic intensity patterns for the 5 September 2022 Mw 6.6 Luding earthquake in southwest China, calculated from peak ground velocity in the 0.02–0.5 Hz frequency range. Although the same earthquake source is used, different crustal velocity models produce markedly different shaking intensities and spatial patterns, illustrating the influence of model choice on post-earthquake ground motion assessment. Colored triangles indicate observed ground motion recorded by fixed seismic stations and strong-motion instruments.
