Rupture Process of Subduction-Zone Earthquakes
This review is primarily concerned with the rupture process of large subduction-zone earthquakes determined by various seismological methods, and with its interpretation in terms of an asperity model. It is not possible to make a thorough and extensive review on the subject because of the limited length. Consequently, this review is inevitably biased toward the works in which I was directly inv...
متن کاملRadiated seismic energy and earthquake source duration variations from teleseismic source time functions for shallow subduction zone thrust earthquakes
[1] Earthquake source time functions deconvolved from teleseismic broadband P wave recordings are used to examine rupture variations for 417 underthrusting earthquakes located on the interplate interface in circum-Pacific subduction zones. Moment-scaled duration of significant moment release varies with depth, with longer-duration events occurring in the shallowest 20 km of the megathrusts. The...
متن کاملMultiple-fault rupture of the M7.1 Hector Mine, California, earthquake from fault zone trapped waves
[1] We studied the complex multiple-faulting pattern of the 40-km-long rupture zone of the 1999 M7.1 Hector Mine, California, earthquake with fault zone trapped waves generated by near-surface explosions and aftershocks, and recorded by linear seismic arrays deployed across the surface rupture. The explosion excited trapped waves, with relatively large amplitudes at 3–5 Hz and a long duration o...
متن کاملInvestigating surface fault Rupture Hazard Mitigation for shallow foundations by EPS wall using Numerical studies
Observing destroyed engineered structures and induced fatality due to faulting motivated engineers to consider possible solution for reducing damage to structures. Mitigations countermeasures should be applied when elusion is not possible. Finite element analyses verified through centrifuge model experiments is implemented in this study. Considering different fault dip Angel, critical position ...
متن کاملExperimental investigation of strong groundmotion due to thrust fault earthquakes
Thrust fault earthquakes are studied in a laboratory earthquake setup previously used to investigate analog strike-slip seismic events. Dynamic mode II ruptures are generated along preexisting faults in an analog material, Homalite H-100, and their interaction with the free surface is studied for both sub-Rayleigh and supershear rupture speeds. High-speed digital photography and laser velocimet...
