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

Geoscientific 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 ...

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

Frontiers 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.

Mathematical modeling of the spread of the coronavirus under strict social restrictions

Mathematical Methods in the Applied Sciences, EarlyView., 2021
We formulate a simple susceptible‐infectious‐recovery (SIR) model to describe the spread of the coronavirus under strict social restrictions. The transmission rate in this model is exponentially decreasing with time. We find a formula for basic reproduction function and estimate the maximum number of daily infected individuals.

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

Annals 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 ...

Forecasting mechanical failure and the 26 June 2018 eruption of Sierra Negra Volcano, Galápagos, Ecuador

Science Advances, 2022
Using recent advancements in high-performance computing data assimilation to combine satellite InSAR data with numerical models, the prolonged unrest of the Sierra Negra volcano in the Galápagos was tracked to provide a fortuitous, but successful ...

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

Frontiers 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.

Eruption forecast for Krafla Caldera

Eos, 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.
