Geoscientists develop new approach to understanding massive volcanic eruptions(图)
Geoscientists approach massive volcanic eruptions
2021/1/18
A team of geoscientists has developed a new way to reconstruct the sizes of volcanic eruptions that occurred thousands of years ago, creating a first-of-its kind tool that can aid in understanding pas...
Geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition zone -- a layer rich in water, crystals and melted rock -- can percolate to the surface...
Crystals once deep inside a volcano offer new view of magma,eruption timing
Crystals deep inside a volcano eruption timing

Volcanologists are gaining a better understanding of what's going on inside the magma reservoir that lies below New Zealand's Mount Tarawera volcano. They're finding a colder, more solid place than th...
Volcanologists are gaining a new understanding of what’s going on inside the magma reservoir that lies below an active volcano, and they’re finding a colder, more solid place than previously thought, ...

The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades – and a new study has found that these sites also may exper...
2017年海底火山查普曼会议(Chapman Conference on Submarine Volcanism:New Approaches and Research Frontiers)
2017年 海底火山查普曼 会议
2017/1/20
Submarine volcanism remains underexplored and underexamined – ¾ of Earth lies beneath water, and a substantial majority of Earth’s volcanic eruptions take place in this subaqueous realm.This conf...
Holidaymakers concerned about fresh volcanic eruptions causing flight-disrupting ash clouds might be reassured by a study setting out the first reliable estimates of their frequency.While the Universi...
New ‘geospeedometer’ confirms super-eruptions have a short fuse(图)
geospeedometer super-eruptions short fuse
2015/11/12
Repeatedly throughout Earth’s history, giant pools of magma greater than 100 cubic miles in volume have formed a few miles below the surface.They are the sources of super-eruptions – gigantic volcanic...
New magnetotelluric soundings in the Mt. Somma-Vesuvius volcanic complex: preliminary results
Magnetotellurics volcanology crustal explorations Mt. Somma-Vesuvius
2015/9/28
During 1997 ten magnetotelluric (MT) soundings were recorded in single-site mode above the Mt. Somma-Vesuvius volcanic area. A first campaign of MT measurements was carried out, during spring, by the ...

PLUME-MoM 1.0: A new integral model of volcanic plumes based on the method of moments
PLUME-MoM moments
2015/8/11
In this paper a new integral mathematical model
for volcanic plumes, named PLUME-MoM, is presented.
The model describes the steady-state dynamics of a plume
in a 3-D coordinate system, accounting f...
New Insights into the Emplacement Dynamics of Volcanic Island Landslides
Volcanic Island Landslides Emplacement Dynamics
2015/7/17
Volcanic islands form the highest topographic structures on Earth and are the sites of some of the planet's largest landslides. These landslides can rapidly mobilize hundreds of cubic kilometers of ro...
Petit-spot volcanism: A new type of volcanic zone discovered near a trench
petit-spot volcano Pacific Plate volatiles basalt
2017/4/12
One extremely young volcano (0.05–1 Ma) and other young volcanoes (1.8, 4.2, 6.0, and 8.5 Ma) composed of strongly
alkaline magma were recently discovered on the abyssal plain of the Early Cretaceous...
Impact vesiculation–a new trigger for volcanic bubble growth and degassing
Impact vesiculation volcanic bubble growth and degassing
2009/10/22
We highlight a potentially important trigger for bubble growth and degassing in volcanic bombs. We have successfully triggered bubble growth in previously unvesiculated samples of silicate melt during...
Geotectonic Setting and Origin of the Youngest Kula Volcanics (Western Anatolia), with a New Emplacement Model
western Anatolia extensional tectonics Kula volcanics geochemistry
2009/7/7
The Quaternary Kula volcanics are Na-dominant in character while all the older volcanic rocks of western Anatolia are generally definitive K-dominant rocks. As a unique example in western Anatolia, th...
