Maximum warning times for imminent volcanic eruptions [PDF]

, 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 ...

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 ...

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.

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 ...

Synthesis of 3-D coronal-solar wind energetic particle acceleration modules [PDF]

, 2014
1. Introduction Acute space radiation hazards pose one of the most serious risks to future human and robotic exploration. Large solar energetic particle (SEP) events are dangerous to astronauts and equipment.

Statistical study of magnetic non-potential measures in confined and eruptive flares [PDF]

, 2018
Using the HMI/SDO vector magnetic field observations, we studied the relation of degree of magnetic non-potentiality with the observed flare/CME in active regions.

Forecasting volcano eruption activity

, 2022
Volcanic activity monitoring typically are based on gas emissions, seismic activity, thermal anomalies, deformation and surface change. These events can be extracted by globally tracked observation data that span the electromagnetic spectrum. Orbital earth observation is generated by sensors focusing on different wavelength.

Testing predictors of eruptivity using parametric flux emergence simulations [PDF]

, 2017
Solar flares and coronal mass ejections (CMEs) are among the most energetic events in the solar system, impacting the near-Earth environment. Flare productivity is empirically known to be correlated with the size and complexity of active regions. Several
