Variability of the Deep‐Water Inputs From the Adriatic and Aegean Seas Over the Period of Sapropel S1 Deposition Based on Foraminiferal Nd Isotopes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Deep‐water of the eastern Mediterranean basins mainly forms in the Adriatic Sea and episodically in the Aegean Sea. However, past and future variability under changing temperature and freshwater inputs remains unclear. We reconstruct seawater εNd from Northern Ionian Sea cores to trace intermediate‐ and deep‐water provenance during the ...

Airborne Photon‐Counting LiDAR for Shallow‐Water Bathymetry With Robust Noise Removal and Depth Retrieval

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Airborne photon‐counting LiDAR has emerged as a promising tool for shallow‐water bathymetry, offering high spatial resolution and penetration depth for coastal and nearshore applications. This study presents an integrated workflow for processing airborne photon‐counting LiDAR data to estimate shallow‐water bathymetry.

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.

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

Comparative Analysis of Seismicity Across Three Depth‐Dependent Slip Regimes in the Japan Trench Subduction Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.
