Laboratory studies on electrical effects during volcanic eruptions
Experimental volcanology explosive volcanism magma fragmentation contact electricity electrical effects
2015/10/8
This laboratory study reports on electrical phenomena during the explosive eruption of a basaltoid silicate melt. Contact electricity is produced in the phase of thermo-hydraulic fracturing of magma d...
Robust satellite techniques for monitoring volcanic eruptions
satellite remote sensing AVHRR robust techniques volcanic aerosols detection
2015/9/28
Through this paper the robust approach to monitoring volcanic aerosols by satellite is applied to an extended set of events affecting Stromboli and Etna volcanoes to assess its performance in automate...
The largest magnitudes of earthquakes associated with some historical volcanic eruptions and their volcanological significance
Earthquake magnitudes distance of perceptibility 1815 eruption of Tambora 1883 eruption of Krakatau magmatotectonic earthquakes
2015/9/28
We know several reports of earthquake swarms associated with volcanic eruptions in the 19th century or older periods when seismographs were not yet available. Even if we have no seismographs, the larg...
Numerical simulation of explosive volcanic eruptions from the conduit flow to global atmospheric scales
numerical modeling explosive volcanic eruptions conduit flow multiphase flow simulation stratospheric sulfate aerosol
2015/9/10
Volcanic eruptions are unsteady multiphase phenomena, which encompass many inter-related processes across the
whole range of scales from molecular and microscopic to macroscopic, synoptic and global....
Constraining the dynamics of volcanic eruptions by characterization of pumice textures
Phlegraean Fields Plinian eruptions vesicle textures magma ascent dynamics
2015/9/10
We have characterized the textures of pumice clasts from Phlegraean Fields to gain insights into the conduit
flow-dynamics of alkaline explosive eruptions. Vesicularities, vesicle number densities, a...
The limits of predictability of volcanic eruptions from accelerating rates of earthquakes
Time-series analysis Volcano seismology Statistical seismology
2014/5/19
Volcanic eruptions are commonly preceded by increased rates of earthquakes. Previous studies argue that in some instances these sequences follow the inverse Omori law (IOL) and that this model could b...
Forecasting volcanic eruptions and other material failure phenomena: An evaluation of the failure forecast method
Forecasting volcanic eruptions other material failure phenomena failure forecast method
2014/5/19
Power‐law accelerations in the mean rate of strain,earthquakes and other precursors have been widely reported prior to material failure phenomena, including volcanic eruptions, landslides and laborato...
