Bromo activity over the last decade: consistent passive degassing and source magma evolution

open access: yesGeoscience Letters, 2022
Bromo is among the very active volcanoes in Indonesia and is known for its recurrent and long-lasting eruptive manifestations. Past volcanic gas studies have revealed Bromo as one of the principal sources of volcanic degassing in Indonesia.

The Mechanism for the Energy Buildup Driving Solar Eruptive Events [PDF]

open access: yesThe Astrophysical Journal Letters, 2017
Abstract The underlying origin of solar eruptive events (SEEs), ranging from giant coronal mass ejections to small coronal-hole jets, is that the lowest-lying magnetic flux in the Sun’s corona undergoes continual buildup of stress and free energy.

Event trees for eruption forecasting at Campi Flegrei caldera

open access: yes, 2021
Available studies for Event Trees at the Campi Flegrei caldera are based on the application of the Bayesian Event Tree model for eruption forecasting (BET_EF) and volcanic hazard (BET_VH). In this document we review such studies, which contain full implementation of the probabilistic eruption forecasting and volcanic hazard at Campi Flegrei ...

Eruptive event generator based on the Gibson‐Low magnetic configuration [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2017
AbstractCoronal 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 the phenomenon.

CALIBRATION OF SIBERIAN RADIOHELIOGRAPH IMAGES

open access: yesSolar-Terrestrial Physics, 2019
We discuss the method for automatic calibration of solar radio images derived from the first stage of the multiwave Siberian Radioheliograph (SRH-48). SRH is a 48-element T-shaped radiointerferometer in the 4–8 GHz frequency range. Since the end of 2017,

Transient changes in bacterioplankton communities induced by the submarine volcanic eruption of El Hierro (Canary Islands). [PDF]

open access: yesPLoS ONE, 2015
The submarine volcanic eruption occurring near El Hierro (Canary Islands) in October 2011 provided a unique opportunity to determine the effects of such events on the microbial populations of the surrounding waters.

Stochastic modelling of explosive eruptive events at Galeras Volcano, Colombia

open access: yes, 2021
A statistical analysis of explosive eruptive events can give important clues on the behaviour of a volcano for both the time- and size-domains, producing crucial information for hazards assessment.

Are Microlensing Events Contaminated by Dwarf Nova Eruptions? [PDF]

open access: yesThe Astrophysical Journal, 1996
We present a simple test that can distinguish between the light curves of candidate microlensing events and those of some dwarf nova eruptions that have a similar morphology. We find that the distribution of the amplitudes versus durations of ordinary dwarf nova eruptions is significantly different from that exhibited by the main body of 53 ...

Clustering of eruptive events from high-precision strain signals recorded during the 2020–2022 lava fountains at the Etna volcano (Italy) [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2023
Lava fountains at the Etna volcano are spectacular eruptive events characterized by powerful jets that expel hot mixtures of solid particles and volcanic gases, easily reaching stratospheric heights.
