Tube coalescence in the Jingfudong lava tube and implications for lava flow hazard of Tengchong volcanism

International Journal of Speleology, 2016
Tube-fed structure occurs as a general phenomenon in Tengchong basic lavas, such as lava tubes, lava plugs and tube-related collapse depressions. We deduced the development of Laoguipo lava flows, which is the longest lava tube (Jingfudong lava tube ...

Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013-14 [PDF]

, 2019
Eruptions of Sinabung volcano, Indonesia have been ongoing since 2013. Since that time, the character of eruptions has changed, from phreatic to phreatomagmatic to magmatic explosive eruptions, and from production of a lava dome that collapsed to a ...

Volcanic Hot-Spot Detection Using SENTINEL-2: A Comparison with MODIS−MIROVA Thermal Data Series [PDF]

, 2020
In the satellite thermal remote sensing, the new generation of sensors with high-spatial resolution SWIR data open the door to an improved constraining of thermal phenomena related to volcanic processes, with strong implications for monitoring ...

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

Deep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Impact vesiculation – a new trigger for volcanic bubble growth and degassing [PDF]

, 2007
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 experiments to simulate volcanic bomb impact, by ...

Morphology and dynamics of inflated subaqueous basaltic lava flows [PDF]

, 2014
International audienceDuring eruptions onto low slopes, basaltic Pahoehoe lava can form thin lobes that progressively coalesce and inflate to many times their original thickness, due to a steady injection of magma beneath brittle and viscoelastic layers ...

Effect of the vintage year on strontium isotopic ratio (87Sr/86Sr) of wines: a Portuguese case study

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Currently, there is a growing need for wine authenticity tools to face the global wine market and deal with adulteration cases. Stable isotope analyses, recognized by the Organization of Vine and Wine as a tool for detecting authenticity fraud, form the basis of the European Wine Databank, which faces limitations concerning the ...
