Project Abstract
 N/A
Intellectual Merit in this project we develop friction constitutive equations for the seismic/aseismic transition (brittle-ductile). in this representation the transition depth depends on temperature and slip speed. this is what the lab data and theory require but numerical models of faulting always assume this transition depth is fixed. there are implications of this for magnitude area relations, surface slip vs fault length relations, for deep coseismic slip during great earthquakes and for all models of the 'transition zone' where non-volcanic tremor and slip occur
