WebApr 13, 2024 · A crucial prerequisite for an accurate estimation of the ETAS parameters is the completeness of the seismic catalog. Unfortunately, due to the strong temporal correlation between earthquakes, there is a significant lack of events, particularly in the immediate aftermath of high-magnitude mainshocks [ 39, 40, 41, 42, 43 ]. WebFeb 1, 2011 · Seismic waves are waves of low-frequency acoustic energy that travel through the earth's layers, which may be generated by extreme geological or man-made …

Seismologists use seismographs to record the amount of time it takes …
Web1 day ago · Seismic-wave response contains the soil and rock elastic features. Previous studies have shown the bearing pores and fluid flowing within of typical near-surface soil and rock have a significant effect on seismic-wave image ( Park et al., 2000; Lin and Miller, 2004; Shin et al., 2013; Gao et al., 2013; Guo et al., 2024 ).
