Observing and Modeling the Spectrum of a Slow Slip Event [PDF]

Journal of Geophysical Research: Solid Earth, 2018
AbstractWe estimate and model the normalized moment rate power spectrum of large slow slip events in Cascadia. We estimate the spectrum using data from GPS‐derived slip inversions, borehole strain records, and beamforming‐based tremor amplitudes. The normalized power spectrum initially decreases with frequency but then may flatten at periods of 1 to 10

Seismic Swarms Unveil the Mechanisms Driving Shallow Slow Slip Dynamics in the Copiapó Ridge, Northern Chile [PDF]

Geophysical Research Letters
Like earthquakes, slow slip events release elastic energy stored on faults. Yet, the mechanisms behind slow slip instability and its relationship with seismicity are debated. Here, we use a seismo‐geodetic deployment to document a shallow slow slip event

The Ocean's Impact on Slow Slip Events

Geophysical Research Letters, 2020
We test the hypothesis that ocean seafloor pressures impart stresses that alter the initiation or termination of transient slow slip events (SSEs) on shallow submarine and near‐coastal faults, using simulated seafloor pressures and a new catalog of SSEs ...

Recurrent slow slip event likely hastened by the 2011 Tohoku earthquake. [PDF]

Proc Natl Acad Sci U S A, 2012
Slow slip events (SSEs) are another mode of fault deformation than the fast faulting of regular earthquakes. Such transient episodes have been observed at plate boundaries in a number of subduction zones around the globe. The SSEs near the Boso Peninsula, central Japan, are among the most documented SSEs, with the longest repeating history, of almost ...

Long-term slow slip event detected beneath the Shima Peninsula, central Japan, from GNSS data

Earth, Planets and Space, 2019
Long-term slow slip events (SSEs), the largest events among slow earthquakes, occur repeatedly along the Nankai Trough, southwest Japan. Their locations, near the locked zones of the plate interface responsible for great megathrust earthquakes in the ...

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.

Characteristic Slow‐Slip Events on the Superstition Hills Fault, Southern California

Geophysical Research Letters
The Superstition Hills Fault (SHF) exhibits a rich spectrum of slip modes, including M 6+ earthquakes, afterslip, quasi‐steady creep, and both triggered and spontaneous slow slip events (SSEs). Following 13 years of quiescence, creepmeters recorded 25 mm

A 15 year slow‐slip event on the Sunda megathrust offshore Sumatra

Geophysical Research Letters, 2015
In the Banyak Islands of Sumatra, coral microatoll records reveal a 15 year‐long reversal of interseismic vertical displacement from subsidence to uplift between 1966 and 1981.

Time-dependent modeling of slow-slip events along the Nankai Trough subduction zone, Japan, within the 2018–2023 period

Earth, Planets and Space
According to a 2013 report by the Earthquake Research Committee of Japan, it was estimated that the probability of the occurrence of the next Nankai earthquake within the next three decades is 70–80%.

Unraveling Scaling Properties of Slow‐Slip Events [PDF]

Geophysical Research Letters, 2020
AbstractA major debate in geophysics is whether earthquakes and slow‐slip events (SSEs) arise from similar failure mechanisms. Recent observations from different subduction zones suggest that SSEs follow the same moment‐duration scaling as earthquakes, unlike qualitatively different scaling proposed by earlier studies.
