About the Mechanism of Volcanic Eruptions [PDF]
arXiv, 2012 A new approach to the volcanic eruption theory is proposed. It is based on a simple physical mechanism of the imbalance in the system "magma-crust-fluid". This mechanism helps to explain from unified positions the different types of volcanic eruptions. A criterion of imbalance and magma eruption is derived.

On the origin of Mount Etna eruptive cycles and Stromboli volcano paroxysms: implications for an alternative mechanism of volcanic eruption [PDF]
arXiv, 2014 New mechanism of imbalance between magma column and fluid volume, accumulated in the magmatic system, is considered as a driving force of the volcanic eruption. Conditions of eruption based on this mechanism are used to explain main features of the volcanic activity (eruptive cycles and paroxysms) of the volcanoes Etna and Stromboli (Italy).

Using impact exsolution to link the Chicxulub collision and Deccan volcanism [PDF]
arXiv, 2017 Observations suggest that impactors and volcanism are connected, but the mechanism that links these events is unknown. This research proposes the impact exsolution hypothesis to explain how planetary scale collisions trigger volcanism. This hypothesis says that when large objects such as asteroids or comets hit planets, they generate seismic waves that

Transient Sulfate Aerosols as a Signature of Exoplanet Volcanism [PDF]
, 2015 Geological activity is thought to be important for the origin of life and for maintaining planetary habitability. We show that transient sulfate aerosols could be a signature of exoplanet volcanism, and therefore a geologically active world. A detection of transient aerosols, if linked to volcanism, could thus aid in habitability evaluations of the ...

Annals of Geophysics, 1996 The correlation between geomagnetic field reversals and volcanism is investigated, according to the speculated consequence on volcanoes of the transient electric currents in the geodynamo, through Joule's heating, before and after every reversal event ...

FORMATION CONDITIONS OF AGATES [PDF]
Минералогия, 2017 Agates are formed at various temperatures, which covers a wide range from those of basaltic and andesitic melts (above 1100 °С) to several tens of centigrade, but at rather low pressures. Their formation in liquid mafic magmas is indicated by correlation

Humanities, 2017 Despite the alleged mastery of humans over nature, contemporary societies are acutely vulnerable to natural hazards. In interaction with vulnerable communities, these transform into catastrophes.

Morphology of the Reykjanes ridge junction with the rift zones of Iceland
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о ЗемлеThe joint zone between subaquatic Reykjanes Ridge and Icelandic rift zones known as Reykjanes Rift Zone is a unique transform zone formed in conditions of interaction between the mantle plume and the mid-oceanic ridge.
