Halide Ions in River Waters in the Kusatsu-Shirane Volcano Area, Gunma.

NIPPON KAGAKU KAISHI, 1997
群馬県草津白根山地域河川水中のハロゲン化物イオソをイオソクロマトグラフ法により測定した.草津白根山の火山活動の影響を強く受けていると考えられる河川水では,一般にハロゲン化物イオソ濃度が高く,同地域のハロゲン元素が大部分草津白根山の火山活動に起因していることがわかった.イオン濃度問の相関をとると,塩化物イオンと臭化物イオンとの間の相関が高く,当地では両イオンがよく似た挙動を示すことがわかった.河川の流下に伴うハロゲン化物イオンの挙動を調べたところ,流下のみによりハロゲン化物イオン濃度比が大きく変動することはないことが示された.主要河川についてのハロゲン化物イオン含有量と流量とから,河川水により草津白根山地域から地域外へ一年間に運ばれるハロゲン化物イオン量を推定したところ,フッ化物イオンが1.4 ...

Sulfur dioxide and particles in quiescent volcanic plumes from Poás, Arenal, and Colima Volcanos, Costa Rica and Mexico [PDF]

, 1984
Measurements of SO2 emission rates and concentrations and of particle distribution, size, shape, and composition were made in quiescent volcanic plumes emitted into the troposphere from Poás and Arenal volcanos, Costa Rica, and Colima volcano, Mexico ...

Sulfur Degassing From Volcanoes: Source Conditions, Surveillance, Plume Chemistry and Earth System Impacts [PDF]

, 2011
International audienceDespite its relatively minor abundance in magmas (compared with H2O and CO2), sulfur degassing from volcanoes is of tremendous significance. It can exert substantial influence on magmatic evolution (potentially capable of triggering

Changes in crater lake chemistry after the 2021 eruption at Aso Volcano, Japan: insights from UAV-based hot water sampling

Journal of Asian Earth Sciences: X
Several volcanoes in Japan have summit craters filled with water, including Zao, Kusatsu-Shirane, Kirishima, and Aso volcanoes. Aso Volcano, located in central Kyushu, is an active caldera volcano with a crater lake whose water volume varies from nearly ...

A controlled-source physical model for long period seismic events [PDF]

Long-period seismic events (LPs) are observed within active volcanoes, hydrothermal systems and hydraulic fracturing. The prevailing model for LP seismic events suggests that they result from pressure disturbances in fluid-filled cracks that generate ...

Microbial life in volcanic lakes [PDF]

, 2015
Lakes in the craters of active volcanoes and their related streams are often characterised by conditions considered extreme for life, such as high temperatures, low pH and very high concentrations of dissolved metals and minerals.

Two electrical conductors beneath Kusatsu-Shirane volcano, Japan, imaged by audiomagnetotellurics, and their implications for the hydrothermal system

, 2006
Kusatsu-Shirane volcano, Japan, is known for its active phreatic eruptions. We have investigated its hydrothermal system by conducting audio-magnetotelluric soundings at 22 stations along a profile that extends across the volcano.

The crater lake of Ilamatepec (Santa Ana) volcano, El Salvador: insights into lake gas composition and implications for monitoring [PDF]

, 2019
We here present the first chemical characterization of the volcanic gas plume issuing from the Santa Ana crater lake, a hyper-acidic crater lake (pH of − 0.2 to 2.5) in north-western El Salvador.
