Spectral precursors of paroxysmal phases of Stromboli

Annals of Geophysics, 1996
In this work we investigate the characteristics of the seismicity at Stromboli volcano during more than two years, i.e. from 11 May 1992 to 21 August 1994.

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

Deep Seismic Tremors in the 2025 Santorini Seismo‐Volcanic Crisis Highlight Magmatic Feeding From a Mid‐Crustal Reservoir

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

Detailed Shallow Shear Velocity Structure in the Nankai Trough From Ambient Noise Differential Adjoint Tomography: Implications for Earthquake Generation Mechanisms

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Seismic and aseismic slip has been reported in the Nankai Trough. In this study we apply ambient noise differential adjoint tomography to obtain a high‐resolution S‐wave velocity (Vs) model in the Nankai Trough. The Vs in the very shallow imbricate thrust zone is higher than that on both the seaward and landward sides.

Tremor signals reveal the structure and dynamics of the Oldoinyo Lengai magmatic plumbing system

Communications Earth & Environment
Earth’s only active carbonatite volcano Oldoinyo Lengai, Tanzania, is a peculiar endmember of volcanism in a young rift segment. Targeted by many petrological studies due to its effusive, cold carbonatite eruptions, its subsurface structure has only been

Abrupt Suppression of Tectonic Tremors Outside the Stress Shadow of Mendocino Earthquakes

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Tectonic tremor is a long‐duration noise‐like seismic signal associated with slow fault motion at major plate boundaries. Due to their remarkable sensitivity to stress perturbations, tremors serve as invaluable probes of the mechanical state and stress conditions deep within fault zones.

Lava Lake Spattering Drives Seismic Tremor During the Geldingadalir 2021 Eruption, Iceland

Geochemistry, Geophysics, Geosystems
Volcanic eruptions generate a continuous ground motion that is commonly referred to as tremor. Although tremor is used worldwide for real‐time monitoring of volcanoes, the mechanisms involved are generally poorly understood.

Giuseppe Imbò and his contribution to volcano seismology

Annals of Geophysics, 1999
Together with Fusakichi Omori and Kenzo Sassa, Giuseppe Imbò is one of the founders of volcano seismology. Imbò's novel idea in volcanic tremor analysis was the introduction of what he called "numeri indici dell'intensità eruttiva" (numerical indices of ...

Model for triggering of non-volcanic tremor by earthquakes

, 2012
There is evidence of tremor triggering by seismic waves emanating from distant large earthquakes. The frequency content of both triggered and ambient tremor are largely identical, suggesting that this property does not depend directly on the nature of the source.

Seismic Exploration for Magmatic Brine Lenses: An Example From Soufrière Hills Volcano, Montserrat

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The majority of metallic ore deposits are related to processes associated with ancient or modern volcanic systems. Beyond geothermal energy production, volcanoes also represent a potential resource of critical metals, including those required for carbon‐neutral technologies. Geothermal metals occur in subsurface fluid reservoirs fed by surface
