Tectonics and Sliver Motion in Costa Rica: Strain Partitioning Constrained by GNSS Velocities Data

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract The tectonic deformation of Costa Rica is controlled by the subduction of the Cocos Plate beneath the Caribbean Plate and the Panama microplate along the Middle America Trench, with oblique convergence in northern Costa Rica to 2024 from 154 permanent stations distributed across Costa Rica to derive for the first time spatially continuous ...

Volcanic Subsidence Triggered by Megathrust Earthquakes

Journal 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

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

E3S 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).

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

Geochemistry, 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 ...

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

Geophysical 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.

Implications for megathrust earthquakes and tsunamis from seismic gaps south of Java Indonesia

, 2020
: Relocation of earthquakes recorded by the agency for meteorology, climatology and geophysics (BMKG) in Indonesia and inversions of global positioning system (GPS) data reveal clear seismic gaps to the south of the island of Java.

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

Geochemistry, 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

Geophysical 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 ...

Megathrust Earthquakes in Oblique Subduction Zones Part 1: The Sagmi Trough [PDF]

, 2012
Since the 2011 Tohoku-oki megathrust earthquake, Japan, it has been recognized that there is a variety of megathrust earthquakes occurring in the world not just only the Chilean type megathrust earthquake.

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

Geophysical 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
