Stress redistribution and slow earthquakes
Tectonophysics, 1982Abstract Earthquakes are usually assumed to result when the gradual stress buildup in a region eventually exceeds some initial local strength. There are observations which suggest that a number of mechanisms must have a significant role in stress redistribution in active earthquake regions.

Slow earthquakes and great earthquakes along the Nankai trough
Earth and Planetary Science Letters, 2002Abstract We have reexamined reports indicating that slow deformation occurred before the great Japan earthquakes of 1944 (Tonankai) and 1946 (Nankaido) and find that the observations are well founded. Although no quantitative models have previously been proposed to explain all of the relevant data we show that they are satisfied by a simple model for

Earthquakes: slow down for safety
Nature, 1996In December 1992, part of the San Andreas fault ruptured. No damage was caused, because instead of lasting for a few seconds, this earthquake sequence took a week. So why are other earthquakes fast?

Teleseismic Search for Slow Precursors to Large Earthquakes
Science, 1994Some large earthquakes display low-frequency seismic anomalies that are best explained by episodes of slow, smooth deformation immediately before their high-frequency origin times. Analysis of the low-frequency spectra of 107 shallow-focus earthquakes revealed 20 events that had slow precursors (95 percent confidence level); 19 were slow earthquakes ...

Slip weakening as a mechanism for slow earthquakes
Nature Geoscience, 2013Slow earthquakes form part of a spectrum of fault behaviour between steady creep and fast rupture during a normal earthquake. Laboratory simulations of slow slip in rock samples taken from the Nankai subduction zone, Japan, reveal similar characteristics to fast earthquakes, implying that some slow slip events could be prematurely arrested earthquakes.

Slow slip: A new kind of earthquake
Physics Today, 2012Sandwiched 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.
