Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

North Sea Storm Surges Amplified by Oscillations Triggered by Preceding Storms

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Storm surges are often treated as independent extremes, yet extratropical cyclones and associated coastal water‐level extremes frequently occur in clustered sequences. Although clustering can increase flood hazard by shortening recovery time, it remains unclear whether preceding storms amplify subsequent surges.

Listening to Tsunami Waves Induced by Glacier Calving

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

The 2021 South Sandwich Islands tsunami: from the Antarctic to the far Northeast corner of the Pacific Ocean

Geoscience Letters
The major earthquake sequence that struck near the South Sandwich Islands in the Antarctic sector of the Atlantic Ocean on August 12, 2021, began with a magnitude M w 7.5 rupture at 18:33 UTC, followed by a more intense M w 8.1–8.3 mainshock three ...

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Global Improvement of Tropical Cyclone Representation Enhances Hindcasts of Extreme Sea Levels Over 68 Years

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract The underrepresentation of tropical cyclones (TCs) in state‐of‐the‐art atmospheric reanalyses such as ERA5 is well known, yet their impact on global hindcasts of extreme sea levels remains largely unaddressed. We show that weak TC signals in ERA5 cause severe underestimation, and in some cases near omission, of TC‐induced storm surges.

Detection of Earthquake Infragravity and Tsunami Waves With Underwater Distributed Acoustic Sensing

Geophysical Research Letters
Underwater Distributed Acoustic Sensing (DAS) utilizes optical fiber as a continuous sensor array. It enables high‐resolution data collection over long distances and holds promise to enhance tsunami early warning capabilities.

DID A SUBMARINE SLIDE TRIGGER THE 1918 PUERTO RICO TSUNAMI? [PDF]

Science of Tsunami Hazards, 2008
The 1918 tsunami that inundated northwest Puerto Rico with up to 6 m waves has been attributed to seafloor faulting associated with the 1918 Mona Canyon earthquake.

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

Simulation of the trans-oceanic tsunami propagation due to the 1883 Krakatau volcanic eruption [PDF]

Natural Hazards and Earth System Sciences, 2003
The 1883 Krakatau volcanic eruption has generated a destructive tsunami higher than 40 m on the Indonesian coast where more than 36 000 lives were lost.
