WebApr 23, 2024 · As demonstrated in Fig. 8, the scatter in seismic-to-acoustic coupling varies between 34 and 77 per cent for seismic stations across ASL. Because this greatly exceeds variability in propagation speeds of the acoustic signal (≈7 per cent, Fig. 3d ), we infer that additional factors are responsible for the relatively large scatter in S/A.
WebMay 31, 2024 · We find three regions with high seismic potential, raising concerns for future occurrence of large tsunamigenic earthquakes. The first region is located westward of the rupture area of the 1995 ( M w 8.0) Antofagasta earthquake, the second region extends for 200 km between the cities of Taltal and Copiapo and the third region extends for 100 km ... WebOct 26, 2024 · Similarly, seismic coupling is larger for smooth saw-cut faults compared to rough faults. The laboratory observations point towards a long-lasting and continuous preparation process leading to failure and large seismic events.
