Migration of Multimodal Deep Crustal Earthquake Swarm Beneath the Abu Volcano Group, Japan

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquakes in the lower crust, where high pressures and temperatures favor ductile deformation, are rare but occasionally occur beneath active volcanic centers, providing insights into deep magmatic processes. We analyze a deep crustal earthquake swarm (February–August 2025) of over 5,000 events beneath the Abu Volcano Group, Japan.

On the Correct Use of Statistical Tests: Reply to "Lies, damned lies and statistics (in Geology)"

, 2011
In a Forum published in EOS Transactions AGU (2009) entitled "Lies, damned lies and statistics (in Geology)", Vermeesch (2009) claims that "statistical significant is not the same as geological significant", in other words, statistical tests may be ...

“Hearing” Wind Speed: Ground Wind Measurement Using Deep Learning From Surveillance Audio

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract This study presents a novel method for measuring ground wind speed (WS) using audio data collected from surveillance cameras. The continuous wavelet transform is employed to model wind sounds and capture the dynamic variations over time. A deep‐learning model integrating attention‐enhanced Convolutional Neural Network and Bidirectional Gated ...

Geometry of the magma chamber beneath Damavand volcano (N Iran) from a joint study of gravity and magnetic data [PDF]

International Journal of Mining and Geo-Engineering
Imaging the intra-sediment magma chamber in the Damavand region, northern Iran, is beyond the resolution of the local seismic observations. Gravity anomalies can precisely image the lateral extension of magma reservoir.

A New Surface Rupture of the 1556 Huaxian M ∼ 8.5 Earthquake Revealed by Rock Surface Luminescence Dating of a Bedrock Fault Scarp and Colluvial Wedges

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Bedrock fault scarps and their associated colluvial wedges provide key evidence for reconstructing paleoearthquakes. We apply rock surface luminescence dating to a bedrock scarp on the Huashan fault in central China, using OSL‐depth profiles (DPs) from multiple heights. Results reveal two coseismic displacements of 6.8 and >1.0 m.

Hydrogravimetry Enables Quantification of Alpine Groundwater Dynamics

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Groundwater plays a critical role in the functioning of alpine hydrological systems, and its importance is expected to increase under climate change. However, quantification of groundwater processes in these systems remains highly uncertain. Terrestrial time‐lapse gravimetry (TLG) is a geophysical and geodetic technique whose measured variable

Identification of Earthquake Precursors Origin and AI Framework for Automatic Classification for One of These Precursors

IEEE Access
Many precursory signal patterns arise before the initial P-wave arrival. The origin of these patterns can be traced to either instrumental or natural ground effects.

Properties and Applications of Love Surface Waves in Seismology and Biosensors

, 2018
Shear horizontal (SH) surface waves of the Love type are elastic surface waves propagat- ing in layered waveguides, in which surface layer is “slower” than the substrate.

Coulomb Pre‐Stress Changes Modulate Coseismic Rupture Kinematics of the 2025 Mw7.7 Myanmar Earthquake Revealed by Space Geodesy

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract We estimate the fault geometry and coseismic slip of the 2025 Myanmar earthquake using multi‐source satellite observations, revealing a nine‐segment rupture structure that transitions from eastward‐dipping in the north to westward‐dipping in the south, with peak slip of ∼6 m and negligible shallow slip deficit.
