Depth estimation of fumarolic gas source deduced by fume pressure measurement

Abstract: The origin of fumarolic gas is hydrothermal boiling in the active fumarolic area and magma degassing in the active volcano where high temperature gas is discharged. The determination of the fumarolic gas source is important for understanding the geothermal activity or the eruption process. However, it is difficult to determine the gas source by geophysical prospecting using seismic or geomagnetic techniques due to the resolution limitation of these techniques. New measurement tools are therefore necessary. The… Show more

“…Interestingly, a similar geometry was described at Kusatsu-Shirane volcano (Japan) by Mori, et al . 39 , who estimated the length of the fumarole conduit (25–40 m) using acoustic resonance.
