Forecasting volcanic ash dispersal and coeval resuspension during the April-May 2015 Calbuco eruption
(Elsevier Science, 2016-07)
Atmospheric dispersion of volcanic ash from explosive eruptions or from subsequent fallout deposit resuspension causes a range of impacts and disruptions on human activities and ecosystems. The April-May 2015 Calbuco ...
Historical accounts provide insight on the geological evolution of the 20th century eruptions at Santorini volcano, Greece
(2023)
The 20th century eruptions of the Santorini volcano in Greece are the most recent activity of the volcano’s long lifespan. While the different eruptions taking place between 1925 and 1950 have traditionally been considered ...
Volcanotectonics: the tectonics and physics of volcanoes and their eruption mechanics
(2022)
The physical processes that operate within, and beneath, a volcano control the frequency, duration, location and size of volcanic eruptions. Volcanotectonics focuses on such processes, combining techniques, data, and ideas ...
Understanding and forecasting phreatic eruptions driven by magmatic degassing
(Springer Nature, 2018-05-18)
This paper examines phreatic eruptions which are driven by inputs of magma and magmatic gas. We synthesize data from several significant phreatic systems, including two in Costa Rica (Turrialba and Poás) which are currently ...
Time-scale wavelet patterns related to the 1998-1999 eruptions of the Colima volcano, and their possible implications for eruption forecasting
(2009)
The seismic activity from one of the most active (documented) periods of the Colima volcano, from October 1998 to July 1999, was analyzed using the wavelet transform, to study the evolution in time of energy content at ...
Magmatic overpressures, volatile exsolution and potential explosivity of fissure eruptions inferred via dike aspect ratios
(2020)
Buoyant magmas abundant in exsolved volatiles (bubbles) drive the rapid upward-propagation of feeder dikes from magma chambers. The consequence of a feeder dike reaching the surface can result in an explosive volcanic ...
Volcanic ash forecast using ensemble-based data assimilation: an ensemble transform Kalman filter coupled with the FALL3D-7.2 model (ETKF–FALL3D version 1.0)
(Geoscientific Model Development, 2020)
Volcanic lightning and plume behavior reveal evolving hazards during the April 2015 eruption of Calbuco volcano, Chile
(2016)
Soon after the onset of an eruption, model forecasts of ash dispersal are used to mitigate the hazards to aircraft, infrastructure, and communities downwind. However, it is a significant challenge to constrain the model ...
Insights on Hydrothermal‐Magmatic Interactions and Eruptive Processes at Poás Volcano (Costa Rica) From High‐Frequency Gas Monitoring and Drone Measurements
(AGU Publications, 2019-02-06)
Identification of unambiguous signals of volcanic unrest is crucial in hazard assessment. Processes leading to phreatic and phreatomagmatic eruptions remain poorly understood, inhibiting effective eruption forecasting. Our ...
