Recurrent Scattering Network Detects Metastable Behavior in Polyphonic Seismo-Volcanic Signals for Volcano Eruption Forecasting

IEEE Transactions on Geoscience and Remote Sensing, 2022
We introduce an end-to-end (E2E) deep neural network architecture designed to perform seismo-volcanic monitoring focused on detecting change. Due to the complexity of volcanic processes, this requires a polyphonic detection, segmentation, and ...

Method selection in short-term eruption forecasting

Journal of Volcanology and Geothermal Research, 2021
Abstract For accurate and timely information on the evolving state of our volcanoes we need reliable short-term forecasts. These forecasts directly impact crisis management from evacuations, exclusion zones, and when it is safe to return. Eruption forecasting should not be viewed as an academic exercise or a theoretical discussion in a back room, nor

An initial assessment of short-term eruption forecasting options in New Zealand

New Zealand Journal of Geology and Geophysics, 2022
There are currently no quantitative short-term eruption forecasts based on peer-reviewed and validated models that are operational for New Zealand’s volcanoes. Specific forecasts produced for work-risk assessments are not generally publicised.

Volcano deformation and eruption forecasting [PDF]

open access: possibleGeological Society, London, Special Publications, 2013
Abstract Recent advances in Global Positioning System (GPS), tilt and Interferometric Synthetic Aperture Radar (InSAR) have greatly increased the availability of volcano deformation data. These measurements, combined with appropriate source models, can be used to estimate magma chamber depth, and to provide information on chamber shape and ...

Forecast of volcanic eruptions by chemical methods [PDF]

open access: possibleBulletin Volcanologique, 1975
From the magmatic emanations differentiation point of view it is possible to calculate some ratios such as F/CO2, Cl/CO2, SO2/CO2, SO2/H2S, H2S/CO2 and CO2/N2 in the tumarolic gases for the forecasting of volcanic activity. In order to predict the cruptions of a volcano it is needed to select several fumaroles or hot springs having different regimes of

Unrest and Eruption Forecasting

2021
The shallow accumulation and/or transfer of magma commonly result in anomalous geodetic, geophysical or geochemical activity of the volcano, named unrest, which is detectable through a monitoring system. At closed conduit volcanoes, every eruption is preceded by unrest.
