Earthquake source characteristics from dynamic rupture with constrained stochastic fault stress
[1] One of the challenging tasks in predicting near-source ground motion for future earthquakes is to anticipate the spatiotemporal evolution of the rupture process. The final size of an event but also its temporal properties (propagation velocity, slip velocity) depend on the distribution of shear stress on the fault plane. Though these incipient stresses are not known for future earthquakes, ...

متن کاملCoherent probability from incoherent judgment.
People often have knowledge about the chances of events but are unable to express their knowledge in the form of coherent probabilities. This study proposed to correct incoherent judgment via an optimization procedure that seeks the (coherent) probability distribution nearest to a judge's estimates of chance. This method was applied to the chances of simple and complex meteorological events, as...
متن کاملModeling Dynamic Rupture in a 3D Earthquake Fault Model
We propose a fourth-order staggered-grid finite-difference method to study dynamic faulting in three dimensions. The method uses an implementation of the boundary conditions on the fault that allows the use of general friction models including slip weakening and rate dependence. Because the staggered-grid method defines stresses and particle velocities at different grid points, we preserve symm...
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...
