Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters
We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while

Performance of Slab Geometry Constraints on Rapid Geodetic Slip Models, Tsunami Amplitude, and Inundation Estimates in Cascadia

Seismica
Tsunamigenic megathrust earthquakes along the Cascadia subduction zone present a major hazard concern. We can better prepare to model the earthquake source in a rapid manner by imbuing fault geometry constraints based on prior knowledge and by ...

How the Transition Region Along the Cascadia Megathrust Influences Coseismic Behavior: Insights From 2‐D Dynamic Rupture Simulations

Geophysical Research Letters, 2019
There is a strong need to model potential rupture behaviors for the next Cascadia megathrust earthquake. However, there exists significant uncertainty regarding the extent of downdip rupture and rupture speed.

Dual megathrust slip behaviors of the 2014 Iquique earthquake sequence [PDF]

, 2015
The transition between seismic rupture and aseismic creep is of central interest to better understand the mechanics of subduction processes. A Mw 8.2 earthquake occurred on April 1st, 2014 in the Iquique seismic gap of northern Chile.

The 2010 Chile Earthquake: a five-year reflection

, 2015
At 3:34AM local time, on February 27th, 2010, a moment magnitude Mw 8.8 megathrust earthquake struck offshore the coast of Chile. The earthquake ruptured a 540 by 200 km mature seismic gap of the underlying subduction pacific plate interlocking mechanism.

Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes

AGU Advances
Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within ...

Interpreting GPS observations of the megathrust earthquake cycle: insights from numerical models [PDF]

, 2023
During a megathrust earthquake cycle, the plates accumulate strain in the interseismic stage due to locking of a portion of the megathrust that separates them. This strain is released during the earthquake and following rapid postseismic relaxation.

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

Geophysical Research Letters
Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating ...

Back to full interseismic plate locking decades after the giant 1960 Chile earthquake

Nature Communications, 2018
Great megathrust earthquakes arise from the sudden release of strain accumulated during centuries of interseismic plate convergence. Here, the authors reconstruct interseismic strain accumulation since the 1960 Chile earthquake, finding a transient ...
