Analysis and quasistatic FE modeling of long period impulsive events associated with explosions at Stromboli volcano (Italy)

Annals of Geophysics, 1999
Broadband seismic measurements performed in 1995 and 1996 in the summit region of Stromboli are analyzed. The experiment in 1995 used an array of four Guralp seismometers and one Wielandt-Streckeisen seismometer.

Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

High‐Resolution Body‐Wave Tomography of Kı̄lauea's Summit Magma Storage System From a Dense Passive and Active Source Experiment

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Imaging magma storage beneath active calderas requires resolving crustal structure at scales comparable to those of individual reservoirs. To identify potential reservoirs beneath Kı̄lauea, Hawai'i, we conducted a hybrid seismic experiment at its summit for 37 days in 2023 that combined more than 1,800 three‐component nodal seismometers with ...

BaSIC: A Bayesian Inversion Model for Basalt Source Investigation and Characterization

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We present BaSIC: Basalt Source Investigation and Characterization, an open‐source Python based Bayesian inversion method to constrain the source mineralogy of basalts. Using bulk rock geochemistry, the model takes the averages and standard deviations of six elemental ratios (Mn/Fe, Zn/Fe, Mn/Zn, Sc/Zn, Co/Fe, and Ga/Sc) for a given basalt ...

Magma Channeling and Crustal Structure of a STEP Fault From Integrated Geological and Geophysical Data: The Central Aeolian Volcanoes (Southern Tyrrhenian Sea)

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Arc volcanism is commonly interpreted as the surface expression of subduction‐related magmatism and its spatial organization is often controlled by lithospheric structures. In arc‐back‐arc systems, slab retreat may promote the transition from compression to extension and the development of Subduction‐Transform Edge Propagator (STEP) faults ...

Disruption of Long-Term Effusive-Explosive Activity at Santiaguito, Guatemala

Frontiers in Earth Science, 2019
Rapid transitions in eruptive activity during lava dome eruptions pose significant challenges for monitoring and hazard assessment. A comprehensive understanding of the dynamic evolution of active lava dome systems requires extensive sets of multi ...

Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal
