Earthquake ruptures modulated by waves in damaged fault zones
Faults are usually surrounded by damaged zones of lower elastic moduli and seismic wave velocities than their host rocks. If the interface between the damaged rocks and host rocks is sharp enough, earthquakes happening inside the fault zone generate reflected waves and head waves, which can interact with earthquake ruptures and modulate rupture properties such as rupture speed, slip rate, and r...
متن کاملPulse-like ruptures induced by low-velocity fault zones
[1] Low-velocity fault zones (LVFZs) are found in most mature faults. They are usually 100–400 m wide and have 20%–60% wave velocity reductions relative to the country rock. To study the effect of LVFZs on earthquake rupture and the radiated wavefield, we conducted two-dimensional (2-D) simulations of dynamic rupture on faults that bisect a LVFZ, considering a range of velocity reductions and w...
متن کاملHemivertebrae, Are They Always Symptomatic?
Most hemivertebrae eventually lead to congenital scoliosis. We describe an infant with an asymptomatic hemivertebra that occurred as part of a VACTERL syndrome. The effects of hemivertebrae, incidence, detection, risks, treatment and prognosis of congenital scoliosis, are outlined. Competing Interests: None
متن کاملEffects of low-velocity fault zones on dynamic ruptures with nonelastic off-fault response
[1] Using a finite element method for elastoplastic dynamic analysis, we examine the effects of a low-velocity fault zone (LVFZ) surrounding a fault on a spontaneous dynamic earthquake rupture. A Mohr-Coulomb failure criterion is used to characterize nonelastic off-fault response to earthquake ruptures. We find that the presence of a LVFZ alters the distribution of off-fault plastic strain and ...
