Ground motion hazard from supershear rupture

WebFeb 17, 2024 · The resulting ground motion typically exhibits a two-sided, long-period, large-amplitude velocity pulse in the fault-normal direction. Backward directivity occurs when the fault rupture propagates ... WebMar 14, 2024 · Then, we jointly invert for the rupture process of the mainshock using the coseismic Interferometric Synthetic Aperture Radar (InSAR) Line-Of-Sight (LOS) displacement data, teleseismic and regional broadband seismic data, and strong-motion data. Finally, we discuss multiple evidence for validating supershear rupture during the …

Some issues on forecast of strong ground motion field

WebAug 8, 2003 · The recorded ground motion displays a strong directivity effect ( Fig. 3 ), because most of the radiated energy is focused along azimuths close to the direction of rupture propagation. This observed azimuthal pattern is explained by the rupture velocity values that we have previously inferred. WebGround motion from two‐dimensional steady state dynamic ruptures is examined for both subshear and supershear rupture velocities. Synthetic seismograms demonstrate that coherent high‐frequency information about the source process rapidly attenuates with distance from the fault for subshear ruptures. Such records provide almost no resolution … bomb cosmetics uk christmas https://tammymenton.com
