Time‐Reversal Full Wavefield Inversion: From Waveform Misfit to Wavefield Focus

Geophysical Prospecting, Volume 74, Issue 7, September 2026.
ABSTRACT We introduce time‐reversal full wavefield inversion (TRFWI), a velocity‐model‐building method that replaces waveform‐misfit minimization with a physically motivated wavefield‐focusing criterion. The recorded data are reversed in time and backpropagated through a trial velocity model; the inversion objective is the degree to which the wavefield

Effective Educational Programs for Disaster Preparedness and Management: A Rapid Evidence Assessment

International Nursing Review, Volume 73, Issue 3, September 2026.
ABSTRACT Aim To evaluate the effectiveness of educational programs on disaster preparedness and management for emergency nurses and nursing students, focusing on teaching methods that enhance readiness and competence. Background The increasing frequency and severity of disasters require healthcare systems to be adequately prepared. Nurses, often on the

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

High Melt Fraction Induced by the Dehydration Melting Near the 410‐km Discontinuity

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The water‐rich mantle transition zone, coupled with the low water storage capacity of the upper mantle, suggests that dehydration melting occurs just above the mantle transition zone near the 410‐km discontinuity. However, the melt fraction produced by the dehydration melting process remains poorly constrained.
