Slow Earthquakes Coincident with Episodic Tremors and Slow Slip Events

Science, 2007
We report on the very-low-frequency earthquakes occurring in the transition zone of the subducting plate interface along the Nankai subduction zone in southwest Japan. Seismic waves generated by very-low-frequency earthquakes with seismic moment magnitudes of 3.1 to 3.5 predominantly show a long period of about 20 seconds.

A Flying Start, Then a Slow Slip

Science, 2005
The human tragedy caused by the Sumatra-Andaman earthquake (moment magnitude 9.3) on 26 December 2004 and its companion Nias earthquake (moment magnitude 8.7) on 28 March 2005 is difficult to comprehend. These earthquakes, the largest in 40 years, have also left seismologists searching for the words and tools to describe the enormity of the geological ...

Slow Slip in Depth

Science, 2010
Geology The largest earthquakes occur at subduction zones, which accommodate the convergence of two tectonic plates. Thanks to dense GPS and seismic networks along these zones, we have a more detailed, and now complicated, view of how this convergence occurs: Many subduction zones exhibit a phenomenon termed “slow slip.” Gomberg et al.

Effects of material property variations on slip estimates for subduction interface slow‐slip events

Geophysical Research Letters, 2015
We investigate the influence of elastic heterogeneity on geodetic inversions of slow-slip events by inverting for slip distributions of four events along the Hikurangi Margin, New Zealand.

Slip-plane and slip-cylinder theorems for slow viscous flow

Acta Mechanica, 1977
Theorems for the slow two-dimensional flow of viscous fluids about slip-planes and slip-cylinders are proven. Examples of the use of the theorems are given.

Reassessing the 2006 Guerrero slow‐slip event, Mexico: Implications for large earthquakes in the Guerrero Gap

Journal of Geophysical Research: Solid Earth, 2015
In Guerrero, Mexico, slow-slip events have been observed in a seismic gap, where no earthquakes have occurred since 1911. A rupture of the entire gap today could result in a Mw 8.2–8.4 earthquake.

Slow Crack Propagation and Slip Correlations

Pure and Applied Geophysics, 2003
The propagation of an interfacial crack through a weak plane of a transparent Plexiglas block is studied experimentally. The toughness is controlled artificially by a sand blasting procedure, and fluctuates locally in space like uncorrelated random noise. The block is fractured in mode I at low speed (10’ - 10-4m/s).

Slow slip: A new kind of earthquake

Physics Today, 2012
Sandwiched between the shallow region of sudden, infrequent earthquakes and the deeper home to continuous viscous motion lies an intermediate realm of intermittent sliding and rumbling. Discovered in recent years, it still harbors many secrets.

Slow Earthquakes, Preseismic Velocity Changes, and the Origin of Slow Frictional Stick-Slip

Science, 2013
Slow Stick-Slip While the character of slow earthquakes has been approximated for some time, precise slip histories and the underlying mechanisms have remained elusive. Kaproth and Marone (p. 1229 ; published online 15 August) have made laboratory observations of repetitive, slow ...
