Brittle and ductile friction and the physics of tectonic tremor
Eric G. Daub, David R. Shelly, Robert A. Guyer, P.A. Johnson
2011, Geophysical Research Letters (38) 1-4
Observations of nonvolcanic tremor provide a unique window into the mechanisms of deformation and failure in the lower crust. At increasing depths, rock deformation gradually transitions from brittle, where earthquakes occur, to ductile, with tremor occurring in the transitional region. The physics of deformation in the transition region remain poorly...

2011, Continental Shelf Research (31) 789-805
The majority of water and sediment discharge from the small, mountainous watersheds of the US West Coast occurs during and immediately following winter storms. The physical conditions (waves, currents, and winds) within and acting upon the proximal coastal ocean during these winter storms strongly influence dispersal patterns. We examined this...
Economic resilience lessons from the ShakeOut earthquake scenario
A. Wein, A. Rose
2011, Earthquake Spectra (27) 559-573
Following a damaging earthquake, “business interruption” (BI)—reduced production of goods and services—begins and continues long after the ground shaking stops. Economic resilience reduces BI losses by making the best use of the resources available at a given point in time (static resilience) or by speeding recovery through repair and reconstruction...
