KVP: a multiscale kurtosis approach for seismic phase picking

Geophysical Journal International
SUMMARY Automatic event detection and phase picking are critical for processing the large volumes of data produced by modern seismological instrumentation. Accurate picking is especially challenging in Distributed Acoustic Sensing (DAS) recordings, where data quality can significantly vary along segments of the fibre due to localized ...

Insights From Two Decades of Seismicity at Columbia Glacier

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions, bathymetry, glacier thickness, surface velocity, and environmental records, we show how ...

Crustal structure beneath the Trondelag Platform and adjacent areas of the Mid-Norwegian margin, as derived from wide-angle seismic and potential field data [PDF]

, 2010
The outer mid-Norwegian margin is characterized by strong breakup magmatism and has been extensively surveyed. The crustal structure of the inner continental shelf, however, is less studied, and its relation to the onshore geology, Caledonian structuring,

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Guidelines for seismic sedimentologic study in non-marine postrift basins

Petroleum Exploration and Development, 2012
This study summarizes the research experiences of non-marine seismic sedimentology in recent years in China and uses Qijia area, Songliao Basin, as a template to establish general guidelines for seismic sedimentology.

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...

Making Phase-Picking Neural Networks More Consistent and Interpretable

The Seismic Record
Improving the interpretability of phase-picking neural networks remains an important task to facilitate their deployment to routine, real-time seismic monitoring. The popular phase-picking neural networks published in the literature lack interpretability

An algorithm for automated phase picking and localization of seismic events. [PDF]

, 2014
Durante gli ultimi anni, la diffusione della sismometria digitale ha reso disponibile una grande quantità di dati utili alla localizzazione di eventi sismici di diversa natura. L’analisi di queste informazioni richiede tuttavia una enorme mole di lavoro,

Monitoring Zoo Elephant Rumble Activity Using Combined Seismic and Acoustic Data

Ecology and Evolution, Volume 16, Issue 3, March 2026.
At the Opel‐Zoo in Germany, we studied elephant rumble activity by recording low‐frequency signals with seismic and infrasound sensors. We detected over 1350 rumbles within 4 weeks that show temporal patterns, demonstrating the benefits of combining both sensing methods.

Detectable seismic consequences of the interaction of a primordial black hole with Earth

, 2012
Galaxies observed today are likely to have evolved from density perturbations in the early universe. Perturbations that exceeded some critical threshold are conjectured to have undergone gravitational collapse to form primordial black holes (PBHs) at a ...
