Episodic Tremor and Slip on the Cascadia Subduction Zone: The Chatter of Silent Slip

  title={Episodic Tremor and Slip on the Cascadia Subduction Zone: The Chatter of Silent Slip},
  author={Garry Rogers and Herb Dragert},
  pages={1942 - 1943}
We found that repeated slow slip events observed on the deeper interface of the northern Cascadia subduction zone, which were at first thought to be silent, have unique nonearthquake seismic signatures. Tremorlike seismic signals were found to correlate temporally and spatially with slip events identified from crustal motion data spanning the past 6 years. During the period between slips, tremor activity is minor or nonexistent. We call this associated tremor and slip phenomenon episodic tremor… Expand

Episodic slow slip events accompanied by non‐volcanic tremors in southwest Japan subduction zone
[1] Episodic slow slip events have been recognized by means of tilt changes in the western Shikoku area, southwest Japan. The crustal tilt deformation was observed repeatedly with a recurrenceExpand
Slip rate and tremor genesis in Cascadia
At many plate boundaries, conditions in the transition zone between seismogenic and stable slip produce slow earthquakes. In the Cascadia subduction zone, these events are consistently observed asExpand
Geodetic and seismic signatures of episodic tremor and slip in the northern Cascadia subduction zone
Slip events with an average duration of about 10 days and effective total slip displacements of severalc entimetres have been detected on the deeper (25 to 45 km) part of the northern CascadiaExpand
Non-volcanic tremor and low-frequency earthquake swarms
It is demonstrated that tremor beneath Shikoku, Japan, can be explained as a swarm of small, low-frequency earthquakes, each of which occurs as shear faulting on the subduction-zone plate interface. Expand
Seismic evidence for megathrust fault-valve behavior during episodic tremor and slip
Using repeated seismic scattering observations in the Cascadia subduction zone, a change in the seismic velocity associated with the LVL after ETS events is observed, which is interpreted as a response to fluctuations in pore-fluid pressure. Expand
Space-time correlation of slip and tremor during the 2009 Cascadia slow slip event
[1] Episodic Tremor and Slip (ETS), involving transient deformations accompanied by emergent, low-frequency tremor occurs in subduction zones around the world. ETS events increase the shear stress onExpand
Episodic tremors and deep slow-slip events in Central California
Abstract Observations of episodic tremor and slip (ETS) events have given insight into the seismic hazards along subduction zones by demonstrating that strain release was possible from slow-slipExpand
Microseismicity but no tremor accompanying slow slip in the Hikurangi subduction zone, New Zealand
Abstract Geodetically-detected episodes of slow slip appear in several subduction zones to be accompanied by bursts of low-frequency coherent noise known as seismic tremor, but whether a singleExpand
Tidal Modulation of Nonvolcanic Tremor
It is argued that tremor occurs on very weak faults because the lithostatic stresses are 105 times larger than those associated with the tides, and therefore much more effectively than they do the genesis of normal earthquakes. Expand
Cascadia subduction tremor muted by crustal faults
Deep, episodic slow slip on the Cascadia subduction megathrust of western North America is accompanied by low-frequency tremor in a zone of high fluid pressure between 30 and 40 km depth. TremorExpand


A Silent Slip Event on the Deeper Cascadia Subduction Interface
Continuous Global Positioning System sites in southwestern British Columbia, Canada, and northwestern Washington state, USA, have been moving landward as a result of the locked state of the CascadiaExpand
Nonvolcanic Deep Tremor Associated with Subduction in Southwest Japan
Deep long-period tremors were recognized and located in a nonvolcanic region in southwest Japan, indicating that the tremors may have been caused by fluid generated by dehydration processes from the slab. Expand
Low-frequency continuous tremor around the Moho discontinuity away from volcanoes in the southwest Japan
[1] Recent enhancement of seismic networks in the Japan Islands revealed occurrence of low-frequency continuous tremors of a beltlike distribution in the southwest Japan, where the subductingExpand
Periodic Slow Earthquakes from the Cascadia Subduction Zone
Because subduction zones generate the largest earthquakes, deep transient creep events can release large amounts of strain energy without detectable seismic shaking, and they are thus known as slow or silent earthquakes. Expand
Elevation changes and the Great 1960 Chilean Earthquake: Support for aseismic slip
We reanalyse the near-field vertical displacement data for the great Chilean earthquake of 1960 to provide constraints on the down-dip slip distribution. A recent study of free oscillation dataExpand
Fluid Processes in Subduction Zones
The location and conse-quences of fluid production in subduction zones can be constrained by consideration of phase diagrams for relevant bulk compositions in conjunction with fluid and rock pressure-temperature-time paths predicted by numerical heat-transfer models. Expand
