Investigating potential icequakes at Llaima volcano, Chile
Volcanica, 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

Nature 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]
arXiv, 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.

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

Matrix Approach of Seismic Imaging: Application to the Erebus Volcano, Antarctica [PDF]
Journal of Geophysical Research: Solid Earth, 123 (2018), 2019 Multiple scattering of seismic waves is often seen as a nightmare for conventional migration techniques that generally rely on a ballistic or a single scattering assumption. In heterogeneous areas such as volcanoes, the multiple scattering contribution limits the imaging-depth to one scattering mean free path, the mean distance between two successive ...

Data acquisition for volcano monitoring [PDF]
Eos, Transactions American Geophysical Union, 2006 In the past decade, systems and techniques for volcano monitoring activities have improved rapidly. The scientific community focused on the development of new methods and techniques, while the electronic systems for experimental activity and monitoring networks were developed mainly by commercial companies.However, these commercial systems often do not

Deformation Study of Papandayan Volcano using GPS Survey Method and Its Correlation with Seismic Data Observation [PDF]
ITB Journal of Engineering Science, 2006 Papandayan volcano located in the southern part of Garut regency, around 70 km away from Bandung city, West Java. Many methods carried out to monitoring the activities of volcano, both continuously or periodically, one of the monitoring method is ...

Frontiers in Earth Science, 2021 A key issue on active volcanoes is to investigate the position and characteristics of the magma reservoirs over time. The aim is to better understand the crustal magma transfer, therefore also to define the volcanic hazard and plan the mitigation ...

Monitoring temporal opacity fluctuations of large structures with muon tomography : a calibration experiment using a water tower tank [PDF]
Scientific Reports 6, Article Number: 23054 (2016), 2015 Usage of secondary cosmic muons to image the geological structures density distribution significantly developed during the past ten years. Recent applications demonstrate the method interest to monitor magma ascent and volcanic gas movements inside volcanoes. Muon radiography could be used to monitor density variations in aquifers and the critical zone
