Adapting to changes in volcanic behaviour: Formal and informal interactions for enhanced risk management at Tungurahua Volcano, Ecuador [PDF]

, 2017
This paper provides an example of how communities can adapt to extreme forms of environmental change and uncertainty over the longer term. We analyse the interactions between scientists, communities and risk managers and examine the interpretation and ...

Mapping the susceptibility of rain-triggered lahars at Vulcano island (Italy) combining field characterization, geotechnical analysis, and numerical modelling [PDF]

Natural Hazards and Earth System Sciences, 2019
The characterization of triggering dynamics and remobilized volumes is crucial to the assessment of associated lahar hazards. We propose an innovative treatment of the cascading effect between tephra fallout and lahar hazards based on probabilistic ...

Magma Storage Below Sabancaya Volcano (Southern Peru) Imaged by Broadband Magnetotellurics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Sabancaya volcano is one of the most active volcanoes in the Central Andes. Its ongoing eruptive process is accompanied by large‐scale deformation, with activation of the Huambo‐Cabanaconde fault system, marked by intense seismicity over an area of about 50 × 30 km2 ${\mathrm{k}\mathrm{m}}^{2}$.

The ash-fall hazard from a Plinian eruption at Colima Volcano, Mexico

Annals of Geophysics, 2010
The historical eruptive activity at Colima Volcano has been characterized by Strombolian and Merapi type eruptions and Vulcanian explosions associated with dome growth, which have ended in a Plinian eruption about every 100 years.

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

Characterizing thermal transitions of the 2018 Shinmoe-dake eruption in Japan using Himawari-8 high-frequency infrared imagery and seismic data

Earth, Planets and Space
Discrete explosive eruptions, including vulcanian eruptions, occur at various stages during the effusion of viscous lava. However, the differences in occurrence time and mechanisms are not yet well understood or categorized.

Self‐Potential Signal Associated With Hydrothermal System Disrupted by Extreme Raining Events; The Case Study of Formica Leo, Piton de la Fournaise, La Réunion Island

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The scoria cones called Formica Leo located at the base of the Piton de la Fournaise terminal cone have been chosen for its significant positive Self‐Potential (SP) anomalies associated with hydrothermal uprising fluids to monitor SP signal and study its dynamics in relation with huge and extreme rainfall events.

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.
