The SO2 camera: A simple, fast and cheap method for ground‐based imaging of SO2 in volcanic plumes
[1] SO2 flux is widely monitored on active volcanoes as it gives a window into the hidden, subsurface magma dynamics. We present here a new approach to SO2 flux monitoring using ultraviolet imagingExpand
Quantification of the gas mass emitted during single explosions on Stromboli with the SO2 imaging camera
We performed measurements using an SO2 imaging camera of the SO2 gas mass emitted during five discrete explosive events on Stromboli volcano on 3 October 2006. The SO2 gas mass released duringExpand
Image-based correction of the light dilution effect for SO2 camera measurements
Abstract Ultraviolet SO 2 cameras are increasingly used in volcanology because of their ability to remotely measure the 2D distribution of SO 2 in volcanic plumes, at a high frequency. However, lightExpand
Volcanic plume measurements using a UAV for the 2014 Mt. Ontake eruption
A phreatic eruption of Mt. Ontake, Japan, started abruptly on September 27, 2014, and caused the worst volcanic calamity in recent 70 years in Japan. We conducted volcanic plume surveys using anExpand
Infrared spectral radiometer: A new tool for remote measurement of SO2 of volcanic gas
We have determined SO2 concentration in fumarolic gas released from the summit crater of Asama volcano, Japan, using an infrared spectral radiometer installed in a site about 4 km away from theExpand
Relation between single very‐long‐period pulses and volcanic gas emissions at Mt. Asama, Japan
[1] Multiple volcanic observations conducted at Mt. Asama, Japan, provide evidence of a link between single very-long-period (VLP) seismic pulses and volcanic gas emissions. SO2 flux measurementsExpand
High SiF4/HF ratio detected in Satsuma-Iwojima volcano’s plume by remote FT-IR observation
Remote FT-IR measurements of volcanic plume of Mt. Iwodake, Satsuma-Iwojima volcano, Japan, were carried out in October 1996 to understand plume chemistry of the volcano, especially characteristicsExpand
Effect of UV scattering on SO2 emission rate measurements
We report the quantitative evaluation of the UV scattering effect on the SO 2 emission rate measurement by the compact UV spectrometer system. Plume spectra were obtained simultaneously at threeExpand
Diffuse CO2 efflux from Iwojima volcano, Izu-Ogasawara arc, Japan
Abstract Iwojima volcano, located on the southernmost part of the Izu-Ogasawara arc, is characterized by the extrusion of trachyte or trachy andesite lavas and pyroclastic rocks of Holocene andExpand
High ClO and ozone depletion observed in the plume of Sakurajima volcano, Japan
[1] Enhanced BrO and ClO in the boundary layer associated with ozone destruction have been observed over salt lakes, as well as in the polar boundary layer. Volcanic plumes are a major natural sourceExpand
