Ground motion intensity measures of the Ms 5.1 Tangshan, China Earthquake on July 12, 2020

On July 12, 2020, a Ms 5.1 moderate earthquake occurred on the north segment of the Tangshan fault in North China, which was the seismogenic fault of the 1976 Ms 7.8 Tangshan earthquake and numerous small-to-moderate earthquakes in recent decades in the Tangshan seismic zone. The Ms 5.1 event was well recorded by dense ground-motion observation stations, including the national strong-motion stations and seismic intensity stations. Totally, 242 three-component acceleration recordings were well processed and the ground motion intensity measures were calculated, including PGAs, PGVs, and 5%-damped PSAs.
