Indication of hydrothermal deposits and ore area on caldera floor and shallow sub-seafloor of the Bayonnaise knoll, based on high-resolution acoustic investigation
hydrothermal deposits high-resolution acoustic observation AUV sub-seafloor SBP
2017/4/10
The Bayonnaise knoll, an active submarine volcano belonging to an actively rifted part of the Izu-Bonin volcanic arc,
exhibits hydrothermal ore deposits on its caldera floor in a region known as the ...
The mechanics of Campi Flegrei unrests as related to plastic behaviour of the caldera borders
Campi Flegrei unrest machanism caldera structure discontinuities plastic effects
2015/10/8
We present here a model which explains the mechanism of generation of unrest episodes at Campi Flegrei caldera from a mechanical point of view. The mechanism involves the effects of plastic zones at t...
A probability tomography approach to the analysis of potential field data in the Campi Flegrei caldera (Italy)
applied geophysics potential fields probability tomography Campi flregrei caldera
2015/9/28
The results of the application of the 3D probability tomography imaging approach to the study of the Campi Flegrei (CF) caldera are presented and discussed. The tomography approach has been applied to...

2015/9/28
The results of an analysis of Dipolar Geoelectrical (DG), Magnetotelluric (MT) and Self-Potential (SP) data
collected over the emerged portion of the Campi Flegrei (CF) caldera (South Italy) are pres...
Gravity changes due to overpressure sources in 3D heterogeneous media: application to Campi Flegrei caldera, Italy
Campi Flegrei Deformation gravity finite element method heterogeneous medium
2015/9/1
Employing 3D finite element method, we develop an algorithm to calculate gravity changes
due to pressurized sources of any shape in elastic and inelastic heterogeneous media. We
consider different s...

Krakatau caldera deposits: revisited and verification by geophysical means
Krakatau caldera Parasitic cones Caldera deposit Drillings at calderas S-wave attenuation Vp/Vs ratio
2015/8/18
One of the differences between volcanic craters and calderas is that the latter bottoms are flatways filled with caldera deposit with lower density in comparison to country rocks. The 1883 Krakatau er...
Calcium-sulfate rich water in landslide area of Tateyama Caldera, northern central Japan
water geochemistry Tateyama caldera Ca–SO4 type water landslide sulfur isotopes
2017/4/11
Chemistry of surface waters from the Tateyama caldera known as a site of frequent landslides in northern central Japan
was investigated to obtain the relationship between their geochemical characteri...
Inflation of Aira Caldera (Japan) detected over Kokubu urban area using SAR interferometry ERS data
Inflation Aira Caldera Kokubu urban area SAR interferometry ERS data
2009/10/22
Nine ERS-1 and ERS-2 descending orbit data acquired over the Aira Caldera between June 1995 and November 1998 were used to create 31 differential interferograms. Although the interferograms exhibit a ...
Stratigraphy of the Volcanic Products Around Nemrut Caldera: Implications for Reconstruction of the Caldera Formation
Nemrut caldera ignimbrite pyroclastics East Anatolia volcanism
2009/7/7
The volcanological development of the Nemrut stratovolcano, located near the southwestern tip of Lake Van in eastern Turkey, is subdivided into three stages: pre-caldera, post-caldera and late stages....

2010/9/28
Nine ERS-1 and ERS-2 descending orbit data acquired over Aira Caldera between June 1995 and November 1998 were used to create 36 differential interferograms. Although the interferograms exhibit a rela...
Chemiographic Analysis of Trioctahedral Smectite-to-Chlorite Conversion Series from the Ohyu Caldera, Japan
Chlorite/smectite mixed layer Corrensite Ohyu caldera Smectite-to-chlorite conversion
2012/1/4
The chemical compositions of chlorite-smectite mixed-layered minerals (C/S) from the Ohyu caldera (Inoue, 1985) are analyzed using M+-4Si-3R2+ diagrams. The assumed original saponite has the following...
