Slow earthquakes in ocean subduction zones shed light on tsunami risk
Slow earthquakes ocean subduction zones tsunami risk
2017/7/21
Understanding "slow-slip" earthquakes on the seafloor -- seismic events that occur over a period of days or weeks -- is giving researchers new insights into undersea earthquakes and the subsequent cre...
The Cascadia Initiative: A Sea Change In Seismological Studies of Subduction Zones

2015/7/17
Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore...

Effect of glacial-interglacial sea-level changes on the displacement and stress field in the forearc and along the plate interface of subduction zones
glacial-interglacial sea-level stress
2015/1/4
Combined seismological, space-geodetic and numerical studies have shown that the seismicity at subduction zones may be modulated by tides and glacier fluctuations on timescales of 1–100 a, becau...

An elastic plate model for interseismic deformation in subduction zones
An elastic plate model interseismic deformation in subduction zones
2014/4/9
Geodetic observations of interseismic surface deformation in the vicinity of subduction zones are frequently interpreted using simple kinematic elastic dislocation models (EDM). In this theoretical st...
Geodetic displacements and aftershocks following the 2001 Mw= 8.4 Peru earthquake: Implications for the mechanics of the earthquake cycle along subduction zones
Geodetic displacements aftershocks following 2001 Bmw= 8.4 Peru earthquake earthquake cycle along subduction zones
2014/4/15
We analyzed aftershocks and postseismic deformation recorded by the continuous GPS station AREQ following theMw= 8.4, 23 June 2001 Peru earthquake. This station moved by 50 cm trenchward, in a N235E ...
Large Trench-Parallel Gravity Variations Predict Seismogenic Behavior in Subduction Zones
Large Trench-Parallel Gravity Variations Predict Seismogenic Behavior in Subduction Zones
2014/4/9
We demonstrate that great earthquakes occur predominantly in regions with a strongly negative trench-parallel gravity anomaly (TPGA), whereas regions with strongly positive TPGA are relatively aseismi...
