Outer rise seismicity related to the Maule, Chile 2010 mega-thrust earthquake and hydration of the incoming oceanic lithosphere [PDF]
, 2012 Most of the recent published geodetic models of the 2010 Maule, Chile mega-thrust earthquake (Mw=8.8) show a pronounced slip maximum of 15-20 m offshore Iloca (similar to 35 degrees S), indicating that co-seismic slip was largest north of the epicenter ...

Shallow Creep in the Leaky Stress Shadow of Locked Zones of Subduction Megathrust
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract In some subduction zones such as Nankai, creeping of the shallow part of the megathrust in the stress shadow of deeper locked zones is detected by seafloor geodetic measurements and/or reflected by slow earthquakes (SEQs). Here we explain that shallow creep occurs in the stress shadow for two reasons: (a) prolonged afterslip and (b) a leaky ...

Fast, accurate solutions for curvilinear earthquake faults and anelastic strain [PDF]
, 2018 Imaging the anelastic deformation within the crust and lithosphere using surface geophysical data remains a significant challenge in part due to the wide range of physical processes operating at different depths and to various levels of localization that

Hydraulic Control of the Foreshocks and Mainshock of the 2017 Valparaíso, Chile, Earthquake
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Slow‐slip events (SSE) are a key mode of aseismic deformation and can enhance fault permeability through fracturing, enabling fluid migration from the overpressured oceanic crust to the plate interface. Whether the resulting poroelastic stress changes promote seismicity and larger megathrust events, however, remains unclear.

Active tectonics and earthquake potential of the Myanmar region [PDF]
, 2014 This paper describes geomorphologic evidence for the principal neotectonic features of Myanmar and its immediate surroundings. We combine this evidence with published structural, geodetic, and seismic data to present an overview of the active tectonic ...

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...

GLOBAL TREND OF MEGATHRUST RESEARCH IN THE LAST TEN YEARS [PDF]
Science of Tsunami Hazards, 2022 Megathrusts have been the subject of more research recently. Therefore efforts are needed to understand the patterns, novelties, research trends, and potential future research areas connected to megathrusts.

Rupture and variable coupling behavior of the Mentawai segment of the Sunda megathrust during the supercycle culmination of 1797 to 1833 [PDF]
, 2014 We refer to periods of subduction strain accumulation beneath the Mentawai Islands, Sumatra, as “supercycles,” because each culminates in a series of partial ruptures of the megathrust in its final decades. The finale of the previous supercycle comprised

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Recent megathrust earthquakes preceded by slow slip events highlight static stress transfer as a key triggering mechanism. However, there are limited insights into the interplay between static stress transfer and elevated fluid pressure before earthquake triggering.

Tsunami hazard analysis of future megathrust Sumatra earthquakes in Padang, Indonesia using stochastic tsunami simulation [PDF]
, 2016 This study assesses the tsunami hazard potential in Padang, Indonesia probabilistically using a novel stochastic tsunami simulation method. The stochastic tsunami simulation is conducted by generating multiple earthquake source models for a given ...
