Journal ArticleDOI
Earthquake triggering by static, dynamic, and postseismic stress transfer
TL;DR: In this paper, the authors used static Coulomb stress changes associated with earthquake slip to explain aftershock distributions, earthquake sequences, and the quiescence of broad, normally active regions following large earthquakes.
Journal ArticleDOI
Delayed triggering of the 1999 Hector Mine earthquake by viscoelastic stress transfer
Andrew M. Freed,Jian Lin +1 more
TL;DR: A three-dimensional viscoelastic model that simulates stress transfer from the ductile lower crust and upper mantle to the brittle upper crust in the 7 years following the Landers earthquake suggests that lower-crustal or upper-mantle flow can lead to postseismic stress increases of up to 1–2 bar at the location of the Hector Mine hypocentre during this time period.
Journal ArticleDOI
Evidence of power-law flow in the Mojave desert mantle
Andrew M. Freed,Roland Bürgmann +1 more
TL;DR: A power-law model of viscous flow in the mantle with n = 3.5 successfully explains the spatial and temporal evolution of transient surface deformation following the 1992 Landers and 1999 Hector Mine earthquakes in southern California and supports the contention that, at least beneath the Mojave desert, the upper mantle is weaker than the lower crust.
Journal ArticleDOI
Transpressional rupture of an unmapped fault during the 2010 Haiti earthquake

TL;DR: The Enriquillo-Plantain Garden strike-slip fault accommodates the relative motion between the North American and Caribbean plates and was thought to have ruptured during the 2010 Haiti earthquake as mentioned in this paper.

TL;DR: The results point to an interior structure that differs from those of the other terrestrial planets: the density of the planet's solid outer shell suggests the existence of a deep reservoir of high-density material, possibly an Fe-S layer.
