Long-Term Monitoring with Fiber Optics Distributed Temperature Sensing at Campi Flegrei: The Campi Flegrei Deep Drilling Project

Sensors, 2019
Monitoring volcanic phenomena is a key question, for both volcanological research and for civil protection purposes. This is particularly true in densely populated volcanic areas, like the Campi Flegrei caldera, which includes part of the large city of ...

Structure and Present State of the Astroni Volcano in the Campi Flegrei Caldera in Italy Based on Multidisciplinary Investigations

Geochemistry, Geophysics, Geosystems, 2022
Despite its known reconstructed volcanic history, the structural setting and present state of the Astroni Volcano of the Campi Flegrei caldera in Italy are still poorly defined.

Seismicity From Modern Magmatic Activity Beneath Taupō Volcano, Aotearoa New Zealand

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Taupō is an active caldera volcano lying beneath Lake Taupō in the central North Island, Aotearoa New Zealand. It last erupted ∼ ${\sim} $1,800 years ago, and today has background seismicity interspersed with unrest episodes, most recently in 2019 and 2022–2023.

Coupled Paleomagnetism and 40Ar/39Ar Dating of Latera Ignimbrites (Vulsini Volcanic District, Italy) Unravel Processes Associated to Piston‐Collapse Calderas

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract Correlation of ignimbrite units at polygenic calderas is mandatory for the reconstruction of caldera‐forming events and proper identification of their eruption dynamics. However, ignimbrites erupted at different times from the same caldera can display similarities in composition and lithology that can hamper proper correlation of outcrops ...

Caldera resurgence and the case-history of Campi Flegrei

Annals of Geophysics
Large calderas formed by explosive eruption are often characterized by a structural uplift of the caldera floor that has been named resurgent dome or block. The analysis of recent unrest at several calderas suggests that the resurgent dome is likely formed by the intrusion of magma at shallow depth below the light caldera infill.

3D Model of the Shallow Crustal Density Distribution of the Krafla Volcanic System in Iceland

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Krafla volcano, located in Iceland's North Volcanic Zone, has been extensively studied using static gravity surveys since 1975. This study integrates measurements acquired between 2022 and 2023 with legacy data to produce a new gravity map of the area. We produce gravity gradient maps to delineate shallow subsurface density features and invert

Twenty Years of Thermal Infrared Observations (2004–2024) at Campi Flegrei Caldera (Italy) by the Permanent Surveillance Ground Network of INGV-Osservatorio Vesuviano

Remote Sensing
Thermal infrared (TIR) time series images acquired by ground, proximal TIR stations provide valuable data to study evolution of surface temperature fields of diffuse degassing volcanic areas.

The Campi Flegrei Blind Test: Evaluating the Imaging Capability of Local Earthquake Tomography in a Volcanic Area

International Journal of Geophysics, 2012
During the 1982–1984 bradyseismic crises in the Campi Flegrei area (Italy), the University of Wisconsin deployed a network of seismological stations to record local earthquakes.

Characteristics of Deep Long‐Period Earthquakes at Alaska Volcanoes From 2005 to 2017

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Deep long‐period earthquakes (DLPs) are often detected near volcanoes from the crust down to the upper mantle. Exhibiting coincidence with volcanic eruptions, DLPs are recognized as potential precursors to volcanic activities yet their detection remains challenging.

Scattering and Absorption Imaging of the Hengill High‐Temperature Geothermal Area, Southwest Iceland

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract We applied 3D scattering and absorption imaging to the Hengill volcanic area (southwest Iceland), where high‐enthalpy geothermal reservoirs are presently harnessed. These techniques have shown the potential for detecting magmatic intrusions and fluid reservoirs in volcanic regions.
