Lab earthquakes show how grains at fault boundaries lead to major quakes: Faults once thought to be 'creeping' yet stable may be at risk for big ruptures - Science Daily

In a 'seismological wind tunnel,' engineers demonstrate the impact of rock gouge -- ground-up rock along a fault boundary -- on earthquake propogation.

By simulating earthquakes in a lab, Caltech engineers have provided strong experimental support for a form of earthquake propagation now thought responsible for the magnitude-9.0 earthquake that deva… [+4987 chars]
