Spatial extent and eruptive potential of hydrothermal system at Numanotaira Crater, Adatara Volcano, Japan, inferred from shallow resistivity structure and diffuse soil gas flux measurement

Earth, Planets and Space
The Numanotaira Crater (NC) of the Adatara Volcano is located in northern Fukushima Prefecture, northeastern Japan, and has repeatedly undergone phreatic eruptions and volcanic lahars.

Ground deformations associated with an overpressurized hydrothermal systems at Azuma volcano (Japan) revealed by InSAR data

Earth, Planets and Space
Inflations at active volcanoes are indicators of overpressure in the subsurface, which is known to be a phenomenon that precedes eruptions. Volcanic overpressure is induced by the injection of magmatic fluids, accumulated magma, or heat supply from ...

Time Varying Crustal Anisotropy at Whakaari/White Island Volcano

Geophysical Research Letters
Whakaari/White Island has been the most active New Zealand volcano in the 21st century, producing small phreatic and phreatomagmatic eruptions, which are hard to predict.

Phreatomagmatic eruption during the buildup of a Triassic carbonate platform (Oman Exotics): eruptive style, associated deformations, and implications on CO2 release by volcanism [PDF]

, 2006
Oman exotics represent remnants of a Triassic carbonate platform (Misfah Formation). Within these carbonates, and coeval with the sedimentation, several basaltic magmatic events occurred mainly as intrusions, also as lava flows and projections.

MAARS OF SOUTH-CENTRAL OREGON By [PDF]

If we could go back in time some 5 to 10 million years to the Pliocene Epoch and recreate the landscape of south-central Oregon, here are some of the things we would probably see: From a plain originally of slight relief, faulting has already ...
