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...
Concurrent eruptions at Etna, Stromboli, and Vulcano: casualty or causality?
Etna Stromboli Vulcano eruption earthquake
2015/9/1
Anecdotes of concurrent eruptions at Etna, Stromboli, and Vulcano (Southern Italy) have persisted for more than 2000 years and volcanologists in recent and past times have hypothesized a causal link a...
Quantitative analysis of the 1981 and 2001 Etna flank eruptions: a contribution for future hazard evaluation and mitigation
flank eruptions future hazard evaluation and mitigation
2015/8/27
Lava flows produced during Etna flank eruptions represent severe hazards for the nearby inhabited areas, which can be protected by adopting prompt mitigation actions, such as the building of diversion...
Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions
South Sarigan Seamount Northern Mariana Islands:
2015/7/17
The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict the...
Hydrothermal Discharge During Submarine Eruptions:The Importance of Detection,Response,and New Technology
Hydrothermal Discharge Submarine Eruptions Detection Response New Technology
2015/7/14
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of h...
Volcanic eruptions are important events in Earth's cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary eject...
Inclusion of ash and SO2 emissions from volcanic eruptions in WRF-Chem: development and some applications
ash SO2 emissions volcanic eruptions WRF-Chem development some applications
2014/12/16
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 sed...
Reconstructing the East Asian monsoon response to major volcanic eruptions: A test of model skill with instrumental and paleoclimate data
Volcanic eruption climate change ancient climate records volcanoes the tropics precipitation
2014/10/22
Global and regional-scale climatic changes caused by volcanic eruptions are difficult to discern conclusively based on limited 20th century climate records. Analyses of paleoclimate records and global...
Intercomparison of Metop-A SO2 measure- ments during the 2010- 2011 Icelandic eruptions
Metop-A Sulphur Dioxide Volcano GOME-2 IASI Brewer
2015/8/18
The European Space Agency project Satellite Monitoring of Ash and Sulphur Dioxide for the mitigation of Avi- ation Hazards, was introduced after the eruption of the Icelandic volcano Eyjafjallajö...
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...
Climate Change Associated with Global Teleconnections, Volcanic Eruptions, and the Arctic’s Snow-Ice Albedo in Godthab, Greenland
Godthab (Greenland) Climate Modes Teleconnections
2013/2/27
To study the impact of climate change on Godthab(Greenland), temperature and precipitation gathered from the Global Historical Climatology Network (GHCN) were analyzed for patterns within 1866-2011. B...
