Magma and Volatile Pathways Beneath Sakurajima Volcano From Self‐Potential, Helium Isotopes, and Broadband Magnetotellurics

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

Interacting Effects of Sea‐Level Rise and Ocean Warming Reshape Thermal Environments on a Coral Reef

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Sea‐level rise (SLR) alters nearshore hydrodynamics, yet its influence on coral reef thermal regimes under climate‐driven ocean warming remains poorly quantified. Using a fully coupled hydrodynamic–wave model validated at Palmyra Atoll, we isolate how SLR modifies temperature variability during a projected 2050 marine heatwave.

Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
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

The Slip Distributions of the 1952 and 2025 Kamchatka Earthquakes From Tsunami Waveforms Recorded Around the Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
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

SWOT Satellite Observations of the Kakhovka Dam Break Flood Highlight Limitations of Outburst Flood Models

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 6 June 2023 failure of the Kakhovka Dam generated a catastrophic outburst flood, leading to loss of life and infrastructure damage. During the flood, daily measurements of water surface elevation were collected by the SWOT satellite, providing the first direct, high‐resolution 2D measurements of a large outburst flood.
