Investigating potential icequakes at Llaima volcano, Chile

open access: yesVolcanica, 2020
Glacially- and magmatically-derived seismic events have been noted to heavily overlap in characteristics, thus there exists the potential for false-alarms or missed warnings at ice-covered volcanoes. Here we present the first study to specifically target

DATA PROCESSING CONCEPTS FOR THE INTEGRATION OF SAR INTO OPERATIONAL VOLCANO MONITORING SYSTEMS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Remote Sensing plays a critical role in operational volcano monitoring due to the often remote locations of volcanic systems and the large spatial extent of potential eruption pre-cursor signals.

Volcano remote sensing with ground-based spectroscopy [PDF]

open access: yes, 2005
The chemical compositions and emission rates of volcanic gases carry important information about underground magmatic and hydrothermal conditions, with application in eruption forecasting.

Subglacial volcano monitoring with fibre-optic sensing: Grímsvötn, Iceland

open access: yesVolcanica, 2023
We present a distributed acoustic sensing (DAS) experiment at Grímsvötn, Iceland. This is intended to investigate volcano-microseismicity at Grímsvötn specifically, and to assess the suitability of DAS as a subglacial volcano monitoring tool in general ...

Unveiling the deep plumbing system of a volcano by a reflection matrix analysis of seismic noise [PDF]

open access: yesarXiv, 2023
In geophysics, volcanoes are particularly difficult to image because of the multi-scale heterogeneities of fluids and rocks that compose them and their complex non-linear dynamics. By exploiting seismic noise recorded by a sparse array of geophones, we are able to reveal the magmatic and hydrothermal plumbing system of La Soufri\`ere volcano in ...

Three years of muography at Mount Etna: results and perspectives [PDF]

open access: yes, 2021
The Summit Craters system represents the point of maximum expression of the persistent tectonic activity at Mount Etna Volcano. The Muography of Etna Volcano (MEV) Project began in 2016 as a pilot project for the successive installation of a permanent muographic observatory.

Responding to eruptive transitions during the 2020–2021 eruption of La Soufrière volcano, St. Vincent

open access: yesNature Communications, 2022
The 2020 – 2021 eruption of La Soufrière volcano transitioned from an effusive to explosive eruption style. Here the authors show that input from multiple monitoring datasets and an evolving conceptual model were key to anticipating and responding to the

Improving the Thermal Infrared Monitoring of Volcanoes: A Deep Learning Approach for Intermittent Image Series [PDF]

open access: yesarXiv, 2021
Active volcanoes are globally distributed and pose societal risks at multiple geographic scales, ranging from local hazards to regional/international disruptions. Many volcanoes do not have continuous ground monitoring networks; meaning that satellite observations provide the only record of volcanic behavior and unrest.
