Volcanic Risk Mitigation that Could Have Been Derailed but Wasn’t: Pinatubo, Philippines 1991

open access: yesFrontiers in Earth Science, 2021
This is the story of a successful risk mitigation effort at Mount Pinatubo in 1991 that could easily have failed. The counterfactuals are the myriad of ways that the effort could have failed but didn’t.

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.

Forecasting eruptions from long-quiescent volcanoes [PDF]

open access: yesBulletin of Volcanology, 2022
AbstractForecasts of eruption are uncertain. The uncertainty is amplified when volcanoes reawaken after several generations in repose, because direct evidence of previous behaviour is rarely available. It fosters scepticism about warnings of volcanic activity and may compromise the success of emergency procedures.

Inclusion of ash and SO2 emissions from volcanic eruptions in WRF-Chem: development and some applications [PDF]

open access: yesGeoscientific Model Development, 2013
We describe a new functionality within the Weather Research and Forecasting (WRF) model with coupled Chemistry (WRF-Chem) that allows simulating emission, transport, dispersion, transformation and sedimentation of pollutants released during volcanic ...

Repeating Earthquakes During Multiple Phases of Unrest and Eruption at Mount Agung, Bali, Indonesia, 2017

open access: yesFrontiers in Earth Science, 2021
In 2017, Mount Agung produced a small (VEI 2) eruption that was preceded by an energetic volcano-tectonic (VT) swarm (>800 earthquakes per day up to M4.9) and two months of declining activity.

Keeping watch over Colombia’s slumbering volcanoes [PDF]

open access: yes, 2015
The Volcanological and Seismological Observatories of Manizales, Pasto and Popayan (Colombian Geological Survey) monitor and study the active volcanoes of Colombia using seismological, geodetic, geochemical and other techniques.

Maximum warning times for imminent volcanic eruptions [PDF]

open access: yes, 2005
Accelerations in seismicity are important precursors to eruptions at volcanoes reawakening after extended repose intervals. These have previously been quantified for subduction-zone settings in terms of the linkage of crustal faults by shearing ...

Application of BET_EF at Mount Etna: a retrospective analysis (years 2001-2005)

open access: yesAnnals of Geophysics, 2011
Advances in volcano monitoring and forecasting need a multidisciplinary collaborative framework. In light of this, a Bayesian Event Tree (BET) approach was performed by the application of the BET for Eruption Forecasting (BET_EF) code to analyze the ...

Eruption forecast for Krafla Caldera

open access: yesEos, Transactions American Geophysical Union, 1982
Since December 1975, Krafla, a volcano in northern Iceland, has been the site of repeated earthquakes, fissuring, and occasional eruptions (see cover figure). Intense monitoring of activity at Krafla has led to the recognition of a repetitive pattern of months‐long inflation in the caldera area, followed by sudden deflation.

Eruptive Event Generator Based on the Gibson-Low Magnetic Configuration [PDF]

open access: yes, 2017
Coronal Mass Ejections (CMEs), a kind of energetic solar eruptions, are an integral subject of space weather research. Numerical magnetohydrodynamic (MHD) modeling, which requires powerful computational resources, is one of the primary means of studying ...
