Bayesian Source Characterization of Oceanic Transform Fault Earthquakes Using Relative Teleseismic Rayleigh Wave Spectra

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Oceanic transform faults frequently generate moderate‐sized earthquakes in quasi‐periodic cycles, offering attractive cases for studying earthquake physics. However, characterizing these remote events remains challenging due to the scarcity of local seismic data.

Megathrust Earthquake Legacy Linked to Changes in Widespread Potential for Methane and Iron Cycling in Glaciated Wetlands

open access: yesAGU Advances
Freshwater wetlands are major sources of global methane emissions through biogenic methanogenesis, a process increasingly influenced by climate change. High latitude wetlands are subject to uniquely altered biogeochemical inputs due to disproportionate ...

Analysis of knowledge improvement among Padang City disaster volunteers through pediatric basic life support education [PDF]

open access: yesE3S Web of Conferences
Padang City is one of the areas with a high risk of earthquakes and tsunamis due to the Mentawai megathrust activity. Children are a vulnerable group requiring special attention during disasters, particularly regarding basic life support (BLS).

Interseismic Coupling Along the Java‐Timor Subduction‐Collision Zone at East Indonesia

open access: yesGeophysical Research Letters
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.

Bidirectional Loading of the Subduction Interface: Evidence From the Kinematics of Slow Slip Events

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Subduction zones host some of Earth's most damaging natural hazards, including megathrust earthquakes and earthquake‐induced tsunamis. A major control on the initiation and rupture characteristics of subduction megathrust earthquakes is how the coupled ...

Volcanic Subsidence Triggered by Megathrust Earthquakes

open access: yesJournal of Disaster Research, 2014
Studies using spaceborne interferometric synthetic aperture radar (InSAR) analysis showed that two megathrust earthquakes – the 2011Mw9.0 Tohoku-oki earthquake in Japan and the 2010Mw8.8Maule earthquake in Chile – triggered unprecedented subsidence in multiple volcanoes. There are strong similarities in the characteristics of the surface deformation in

Seismotectonics and Crustal Structure in the Southern Dominican Republic Offshore Margin: Implications on the Tsunami Potential

open access: yesGeochemistry, Geophysics, Geosystems
Many coastal areas of the southern Dominican Republic experience considerable population pressure accompanied by important economic activity. The southern offshore margin is characterized by significant seismicity and active geological processes. Because

Unusually large tsunamis frequent a currently creeping part of the Aleutian megathrust

open access: yesGeophysical Research Letters, 2016
Current models used to assess earthquake and tsunami hazards are inadequate where creep dominates a subduction megathrust. Here we report geological evidence for large tsunamis, occurring on average every 300–340 years, near the source areas of the 1946 ...

Azimuthal Seismic Anisotropy in the Upper Crust of the Japanese Islands Induced by the 2011 Tohoku‐Oki Megathrust Earthquake

open access: yesGeophysical Research Letters, 2018
We investigated VP/VS changes in the upper crust of the Japanese islands after the 2011 MW9.0 Tohoku‐Oki megathrust earthquake. Abrupt VP/VS changes with azimuth‐dependent variations were observed after the megathrust earthquake. The VP/VS changes ranged
