Journal ArticleDOI
Dilatant strengthening as a mechanism for slow slip events
TL;DR: In this paper, slow slip events in subduction zones were modeled with 2-dimensional elasticity, rate-state friction, and a dilatancy law where porosity evolves toward steady state ss over distance dc and ss = 0 + ln(v/v0); v is slip speed.
Journal ArticleDOI
Space-time correlation of slip and tremor during the 2009 Cascadia slow slip event
TL;DR: In this paper, the authors invert GPS data from the August 2009 Episodic Tremor and Slip (ETS) event in central Cascadia for the space-time evolution of fault slip-rate.
Journal ArticleDOI
Slow-slip evolves into megathrust earthquakes in 2D numerical simulations
Paul Segall,Andrew M. Bradley +1 more
TL;DR: In this article, slow slip events (SSE) in many subduction zones incrementally stress the adjacent locked megathrust, suggesting that they could potentially either trigger or evolve into damaging earthquakes.
Journal ArticleDOI
The Role of Thermal Pressurization and Dilatancy in Controlling the Rate of Fault Slip
Paul Segall,Andrew M. Bradley +1 more
TL;DR: In this article, the authors explore the hypothesis that whether slip is slow or fast depends on the competition between dilatancy, which decreases fault zone pore pressure p, and thermal pressurization, which increases p.
Journal ArticleDOI
Albany: using component-based design to develop a flexible, generic multiphysics analysis code
Andrew G. Salinger,Roscoe A. Bartlett,Andrew M. Bradley,Qiushi Chen,Irina Demeshko,Xujiao Gao,Glen A. Hansen,Alejandro Mota,Richard P. Muller,Erik Nielsen,Jakob T. Ostien,Roger P. Pawlowski,Mauro Perego,Eric T. Phipps,WaiChing Sun,Irina Kalashnikova Tezaur +15 more
TL;DR: The overall design of Albany is presented, and the details of the integration of many of the components involved are discussed, to show the reader the wide variety of solution components that are available and what is possible when they are combined within a simulation capability.
