Pulse-like and crack-like dynamic shear ruptures on frictional interfaces: experimental evidence, numerical modeling, and implications
Earthquake physics Mechanics of faulting Pulse-like rupture Shear cracks Velocity-dependent friction Linear slip-weakening friction
2014/4/8
Destructive large earthquakes occur as dynamic frictional ruptures along pre-existing interfaces (or faults) in the Earth’s crust. One of the important issues in earthquake dynamics is the local durat...
Faults self-organized by repeated earthquakes in a quasi-static antiplane crack model
Faults self-organized by repeated earthquakes quasi-static antiplane crack model
2009/11/13
We study a 2D quasi-static discrete crack anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transferred to al...
Deformation due to a pressurized horizontal circular crack in an elastic half-space, with applications to volcano geodesy
displacement intrusion magma modelling sill theory
2014/4/9
We consider deformation due to sill-like magma intrusions using a model of a horizontal circular crack in a semi-infinite elastic solid. We present exact expressions for vertical and horizontal displa...
