Connecting slow earthquakes to huge earthquakes
Science, 2016Slow earthquakes are characterized by a wide spectrum of fault slip behaviors and seismic radiation patterns that differ from those of traditional earthquakes. However, slow earthquakes and huge megathrust earthquakes can have common slip mechanisms and are located in neighboring regions of the seismogenic zone.

Physics of the Earth and Planetary Interiors, 1979
Anomalous earthquakes such as creep events, tsunami earthquakes and silent earthquakes have been reported in the recent literature. In this paper we discuss an anomalous “slow earthquake” that occurred on June 6, 1960 in southern Chile. Although the surface-wave magnitude of this event is only 6.9, it excited anomalously large long-period multiple ...

Slow earthquakes triggered by typhoons
Nature, 2009The first reports on a slow earthquake were for an event in the Izu peninsula, Japan, on an intraplate, seismically active fault. Since then, many slow earthquakes have been detected. It has been suggested that the slow events may trigger ordinary earthquakes (in a context supported by numerical modelling), but their broader significance in terms of ...

A scaling law for slow earthquakes
Nature, 2007Recently, a series of unusual earthquake phenomena have been discovered, including deep episodic tremor, low-frequency earthquakes, very-low-frequency earthquakes, slow slip events and silent earthquakes. Each of these has been demonstrated to arise from shear slip, just as do regular earthquakes, but with longer characteristic durations and radiating ...

Slow Earthquakes Coincident with Episodic Tremors and Slow Slip Events
Science, 2007We 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.

Slow earthquakes and stress redistribution
Nature, 1978Strainmeters with high sensitivity over long periods have enabled the detection and identification of slow earthquakes: seismic events which produce records similar to those from normal earthquakes except that the time scale for the rupture process is considerably longer.

Tsunami Efficiency Due to Very Slow Earthquakes
Seismological Research Letters, 2020Abstract 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

Slow Earthquakes and Nonvolcanic Tremor
Annual Review of Earth and Planetary Sciences, 2011Nonvolcanic 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 ...

Science, 1998
SEISMOLOGYTheoretical and lab studies have suggested that faults should give off warning signs as they edge toward rupture, but no one has yet found what they are. Now, researchers using a seemingly roundabout method--testing for the effects of tides on quake timing--offer the strongest evidence yet that some faults do start to slip, rapidly ...
