Structural barriers control the spatial extent of slow earthquake slip [PDF]

Nature Communications
Recent seismological and geodetic observations have revealed shallow slow earthquakes on subduction megathrusts, offering an opportunity to explore the factors controlling megathrust slip.

Electromagnetic imaging reveals insufficient fluids to explain shallow megathrust creep at the Shumagin Gap [PDF]

Nature Communications
The Shumagin Gap, a creeping segment of the Alaska subduction zone characterized by tsunamigenic structures, experienced a deep rupture during the July 2020 M7.8 earthquake.

Offshore Landward Motion Shortly After a Subduction Earthquake Implies Rapid Relocking of the Shallow Megathrust

Geophysical Research Letters, 2023
Geodetic observations after large subduction earthquakes reflect multiple postseismic processes, including megathrust relocking. The timing of relocking and the observational constraints on it are unclear.

Limited Shallow Slip for the 2020 Simeonof Earthquake, Alaska, Constrained by GNSS‐Acoustic

Geophysical Research Letters, 2023
The 22 July 2020 Mw7.8 Simeonof earthquake was a deep megathrust event that ruptured along the Shumagin segment of the Alaska‐Aleutian subduction zone. This earthquake occurred ∼250 km from a seafloor geodetic GNSS‐Acoustic site IVB1, where we observed a

Probabilistic Tsunami Hazard Analysis for Vancouver Island Coast Using Stochastic Rupture Models for the Cascadia Subduction Earthquakes

GeoHazards, 2023
Tsunami hazard analysis is an essential step for designing buildings and infrastructure and for safeguarding people and assets in coastal areas. Coastal communities on Vancouver Island are under threat from the Cascadia megathrust earthquakes and ...

Learning from a Disastrous Megathrust Earthquake

Eos, 2021
Ten years of interdisciplinary studies since the disastrous Tohoku-oki earthquake have improved our knowledge of earthquake-cycle processes and hazard, but prediction of such events remains elusive.

Seismo‐Turbidites in Aysén Fjord (Southern Chile) Reveal a Complex Pattern of Rupture Modes Along the 1960 Megathrust Earthquake Segment [PDF]

, 2020
Grainsize analysis and end-member modeling of a long sediment core from Aysen Fjord (southern Chile) allows to identify over 25 seismo-turbidites in the last 9,000 years.

Recent Relative Sea‐Level Changes Recorded by Coral Microatolls in Southern Ryukyus Islands, Japan: Implication for the Seismic Cycle of the Megathrust

Geochemistry, Geophysics, Geosystems, 2023
The seismic hazard related to megathrust earthquakes in the Ryukyus (southern Japan) is poorly constrained as no large earthquake has been reported there.
