Periodic slow slip triggers megathrust zone earthquakes in northeastern Japan [PDF]
A silent and periodic earthquake trigger Large earthquakes that hit places such as Japan seem to be preceded by subtle and silent deformation. Uchida et al. show that these “slow-slip events” are quasi-periodic in the megathrust zone in Japan.

Stress transfer and strain rate variations during the seismic cycle [PDF]
The balance of forces implies stress transfers during the seismic cycle between the elastobrittle upper crust and the viscoelastic lower crust. This could induce observable time variations of crustal straining in the interseismic period.

Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated a trans‐Pacific tsunami. The hypocenter was nearly at the same location as the 1952 great earthquake (Mw 8.8–9.0). Determining whether the 2025 rupture reached the trench and how it relates to the 1952 event is crucial for understanding slip behavior along the Kamchatka subduction zone. We

Slip rate deficit and earthquake potential on shallow megathrusts
Most destructive tsunamis are caused by seismic slip on the shallow part of offshore megathrusts. The likelihood of this behaviour is partly determined by the interseismic slip rate deficit, which is often assumed to be low based on frictional studies of shallow fault material.

Interseismic Coupling Along the Java‐Timor Subduction‐Collision Zone at East Indonesia
The Java‐Timor subduction‐collision zone is one of the most tectonically complicated structures along the strike of the Indonesia‐Australia convergence. This complexity makes it difficult to interpret observations of interseismic deformation.

Ground Shaking and Seismic Source Spectra for Large Earthquakes around the Megathrust Fault Offshore of Northeastern Honshu, Japan [PDF]
Large earthquake ruptures on or near the plate boundary megathrust fault offshore of northeastern Honshu, Japan, produce variable levels of regional high‐frequency ground shaking.

Abstract The July 2025 Kamchatka earthquake (Mw 8.8) generated Pacific‐wide tsunamis. Inversion of 40 DART bottom pressure records revealed a large (∼9 m) slip at 200–400 km southwest of the epicenter. This model reproduces the local geodetic data, and is similar to other finite fault models based on teleseismic and geodetic data. Inversion of the tide

Large fault slip peaking at trench in the 2011 Tohoku-oki earthquake
The 2011 Tohoku-oki earthquake slip occurred on the shallowest part of the megathrust, but the nature of the shallow slip has been poorly constrained. Here, the authors model bathymetry differences before and after the earthquake to determine that the ...

Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.

Tsunami evacuation plans for future megathrust earthquakes in Padang, Indonesia, considering stochastic earthquake scenarios [PDF]
Abstract. This study develops tsunami evacuation plans in Padang, Indonesia, using a stochastic tsunami simulation method. The stochastic results are based on multiple earthquake scenarios for different magnitudes (Mw 8.5, 8.75, and 9.0) that reflect asperity characteristics of the 1797 historical event in the same region.
