Evidence of Seismic Slip on a Large Splay Fault in the Hikurangi Subduction Zone

Geochemistry, Geophysics, Geosystems, 2021
The Hikurangi subduction zone is capable of producing moderate to large earthquakes as well as regularly repeating slow slip events. However, it is unclear what structures host these different slip styles along the margin.

A large slow slip event on the central Hikurangi subduction interface beneath the Manawatu region, North Island, New Zealand

, 2006
We present continuous GPS observations of a surface deformation episode in the Manawatu region of the North Island, New Zealand, lasting 18 months from January 2004 to June 2005.

Variations in slow slip moment rate associated with rapid tremor reversals in Cascadia [PDF]

, 2016
During large slow slip events, tremor sometimes propagates in the reverse along-strike direction for a few hours, at speeds 10 to 40 times faster than the forward propagation.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation

An unexplained tsunami: Was there megathrust slip during the 2020 Mw7.6 Sand Point, Alaska, earthquake?

Seismica
On October 19, 2020, the Mw7.6 Sand Point earthquake struck south of the Shumagin Islands in Alaska. Moment tensors indicate the earthquake was primarily strike-slip, yet the event produced an enigmatic tsunami that was larger and more widespread than ...

Global subduction slow slip events and associated earthquakes

Science Advances
Three decades of geodetic monitoring have established slow slip events (SSEs) as a common mode of fault slip, sometimes linked with earthquake swarms and in a few cases escalating to major seismic events. However, the connection between SSEs and earthquake hazard has been difficult to quantify and contextualize beyond regional studies.

Slow slip events in the early part of the earthquake cycle

Journal of Geophysical Research: Solid Earth, 2017
AbstractIn February 2014 aMw = 7.0 slow slip event (SSE) took place beneath the Nicoya Peninsula, Costa Rica. This event occurred 17 months after the 5 September 2012,Mw = 7.6, earthquake and along the same subduction zone segment, during a period when significant postseismic deformation was ongoing.

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

, 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.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Do Slow Slip Events Trigger Large and Great Megathrust Earthquakes?

, 2018
Slow slip events have been suggested to trigger subduction earthquakes. However, examples to date have been poorly recorded, occurring offshore, where data are sparse. Better understanding of slow slip events and their influence on subsequent earthquakes
