Tsunami Efficiency Due to Very Slow Earthquakes

Seismological Research Letters, 2020
Abstract Often, tsunami “sources” have been treated as a quasistatic problem. Initial studies have demonstrated that, for earthquake rupture velocities in the span of 1.5–3  km/s, the kinematic and static part of the tsunami can be treated separately. However, very slow earthquake rupture velocities in the span of 0.1–1  km/s have not

Stress redistribution and slow earthquakes

Tectonophysics, 1982
Abstract 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 Nonvolcanic Tremor

Annual Review of Earth and Planetary Sciences, 2011
Nonvolcanic tremor is observed in close association with geodetically observed slow-slip events in subduction zones. Accumulating evidence points to these events as members of a family of slow earthquakes that occur as shear slip on the downdip extensions of fault zones in a regime that is transitional between a frictionally locked region above and a ...

Teleseismic Search for Slow Precursors to Large Earthquakes

Science, 1994
Some 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 ...

Earthquakes: slow down for safety

Nature, 1996
In 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?

Slip weakening as a mechanism for slow earthquakes

Nature Geoscience, 2013
Slow 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, 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.
