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 ...

Controls on Magma Output From Stromboli's Plumbing System

Journal of Geophysical Research: Solid Earth
Abstract Quantifying magma output over variable timescales is essential for understanding persistently active volcanoes. We analyze magma output at Stromboli (during 2000–2025) using satellite thermal data integrated with a comprehensive database of volcanic activity.

High Temporal Resolution Record of Flare‐Up Magmatism Reveals Tectonic and Local Controls on Crustal Thickening in the Cretaceous Continental Arc of the North Cascades

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Magmatic output in continental arcs is often variable, with short‐lived flare‐ups separated by prolonged lulls. Flare‐ups commonly coincide with increased crustal thickness, which has been interpreted as both a cause and a consequence of elevated magmatism.

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 ...

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

The cascading origin of the 2018 Kīlauea eruption and implications for future forecasting

Nature Communications, 2020
The 2018 summit and flank eruption of Kīlauea Volcano was one of the largest volcanic events in Hawaiʻi in 200 years. Data suggest that a backup in the magma plumbing system at the long-lived Puʻu ʻŌʻō eruption site caused widespread pressurization in ...
