Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.

Large (∼80 km) Shield Volcanoes on the Moon Possibly Fed by Shallow Magma Reservoirs

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Large shield volcanoes are among the most prominent volcanic structures on terrestrial bodies. The Moon, while volcanically very active in the past and hosting various volcanic features, seems to lack such large shield volcanoes. Here, we report the identification of two lunar volcanic domes (Prinz‐Harbinger and Theophilus) with diameters ...

Understanding silicic volcanism: Constraints from elasticity and failure of vesicular magma [PDF]

, 2005
Volcanic eruptions are one of the most spectacular and dangerous natural phenomena. Volcanic activity can either be effusive, dominated by quiescent emission of lava or explosive, dominated by the eruption of pyroclastic material.

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients.

Long Unrest (2007–2025) at Laguna del Maule: Linking Strain Field and Seismicity From GNSS and Seismic Data

Geophysical Research Letters
The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics.

Magma Fizz: Tremor During the Kīlauea Summit Reservoir Decompression

Journal of Volcanology and Geothermal Research
Typical eruptions at Kīlauea volcano involve the evacuation of magma from the summit and/or south caldera reservoirs towards the East or Southwest rift zones. The reservoir drainage provokes the summit deflation, and on extreme occasions, such as in 2018, the summit caldera collapse.

Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

AGU Advances
Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions.
