Research on a Deep Learning‐Based Inversion Method for Surface Wave Dispersion Spectra
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract The near‐surface shear‐wave velocity structure is crucial for geological engineering and near‐surface exploration. Surface wave inversion is a key technique for obtaining the velocity structure, but traditional methods suffer from limitations such as heavy reliance on the initial model, high computational cost, and susceptibility to local ...

Geophysical Prospecting, Volume 74, Issue 8, October 2026.ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract We present new results from ambient noise tomography and azimuthal anisotropy analysis of the DOMERAPI data set to investigate crustal structure beneath the Merapi‐Merbabu‐Telomoyo region in central Java. The 3D shear‐wave velocity (Vs) model reveals a prominent high‐Vs anomaly extending from south of Merapi through Merbabu to Telomoyo ...

Chorus Wave‐Induced Ionospheric Variability
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Electron microbursts are short‐lived but intense electron precipitation and constitute a significant source of electron losses into the ionosphere and lower atmosphere. They are primarily produced by wave‐particle interaction with chorus waves in the magnetosphere.

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.

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Glacier bed topography is crucial for modeling ice mass loss. However, heavily crevassed regions are challenging to survey using conventional methods, leading to data gaps. We establish a passive seismic approach exploiting naturally occurring crevassing events recorded with a dense seismic array to image the ice–bed interface without spatial ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract This study investigates the roles of neutral winds, composition and atmospheric waves in storm‐time post‐midnight equatorial plasma bubble (EPB) development using the coupled SAMI3‐WACCMX model. Simulations reveal the formation of post‐midnight EPBs extending beyond 1,500 km in altitude and persisting into the post‐sunrise period.
