Monitoring of fumarole discharge and CO2 soil degassing in the Azores: contribution to volcanic surveillance and public health risk assessment
volcanology geochemistry soil degassing monitoring risk
2015/9/10
Fluid geochemistry monitoring in the Azores involves the regular sampling and analysis of gas discharges from
fumaroles and measurements of CO2 diffuse soil gas emissions. Main degassing areas under ...
Vulcamera: a program for measuring volcanic SO2 using UV cameras
Ultraviolet camera volcanic sulfur dioxide image acquisition
2015/8/27
We report here on Vulcamera, a stand-alone program for the determination of volcanic SO2 fluxes using ultraviolet cameras. The code enables field image acquisition and all the required post-processin...
Recent advances in ground-based ultraviolet remote sensing of volcanic SO2 fluxes
Volcanology Volcanic Gases Volcano monitoring Volcanic effects upon atmosphere Atmospheric instruments and techniques
2015/8/27
Measurements of volcanic SO2 emission rates have been the mainstay of remote-sensing volcanic gas geochemistry for almost four decades, and they have contributed significantly to our understanding of ...
Chemical and isotopic composition of fumarolic gases at Iwate volcano, Japan, during and after seismic activity in 1998: implications for the modification of ascending volcanic gases
Volcanoes volcanic earthquakes expectations and volcanic gases seismic activity the concentration of hydrochloric acid
2015/8/27
In 1998, there were many volcanic earthquakes recorded at Iwate volcano, Japan. Although an eruption was anticipated, it never occurred. Fumarolic gases were sampled at the volcano on six occasions du...
Geochemical monitoring of volcanic lakes. A generalized box model for active crater lakes
Geochemical monitoring Active crater lakes Box model Mass budget Isotope and chemical budget
2015/8/27
In the past, variations in the chemical contents (SO42−, Cl−, cations) of crater lake water have not systematically demonstrated any relationships with eruptive activity. Intensive paramet...
Hydrochemistry and isotopic characteristics of non-volcanic hot springs around the Miocene Kofu granitic complex surrounding the Kofu Basin in the South Fossa Magna region, central Honshu, Japan

Mineral-Chemical Constraints on the Miocene Calc-alkaline and Shoshonitic Volcanic Rocks of Western Turkey: Disequilibrium Phenocryst Assemblages as Indicators of Magma Storage and Mixing Conditions
western Anatolia magma evolution magma mixing compositional zoning disequilibrium parameters crustal magma chambers
2009/7/7
Early to Middle Miocene (22 to 15 Ma) volcanic activity across western Turkey produced a series of lavas and pyroclastic deposits with calc-alkaline and shoshonitic affinities. The erupted magmas show...
Isotopic fractionation of SO2 and H2S gases during the absorption by KOH solution, with the application to volcanic gas monitoring at Miyakejima Island, Japan
volcanic gas Miyakejima isotopic fractionation diffusion sulfur
2017/8/10
The chemical trap method has been used for monitoring of volcanic activity. In this method, a strong alkaline water solution was exposed in ambient air. Acidic gases, such as SO2, H2S, HCl and HF are ...
