Inferring earthquake physics and chemistry using an integrated field and laboratory approach

A Niemeijer, G Di Toro, WA Griffith, A Bistacchi… - Journal of Structural …, 2012 - Elsevier
Earthquakes are the result of a combination of (1) physico-chemical processes operating in
fault zones, which allow ruptures to nucleate and rock friction to decrease with increasing …

Conditions under which velocity-weakening friction allows a self-healing versus a cracklike mode of rupture

G Zheng, JR Rice - Bulletin of the Seismological Society …, 1998 - pubs.geoscienceworld.org
Slip rupture processes on velocity-weakening faults have been found in simulations to occur
by two basic modes, the expanding crack and self-healing modes. In the expanding crack …

Modeling dynamic rupture in a 3D earthquake fault model

R Madariaga, K Olsen… - Bulletin of the …, 1998 - pubs.geoscienceworld.org
We propose a fourth-order staggered-grid finite-difference method to study dynamic faulting
in three dimensions. The method uses an implementation of the boundary conditions on the …

E Tinti, E Fukuyama, A Piatanesi… - Bulletin of the …, 2005 - pubs.geoscienceworld.org
We propose a new source-time function, to be used in kinematic modeling of ground-motion
time histories, which is consistent with dynamic propagation of earthquake ruptures and …

Integrated seismic source model of the 2015 Gorkha, Nepal, earthquake
