A laboratory volcano (5): application to Kilauea
decrease in gas flux during fire
fountains is confirmed
for the period after the fire
fountain episodes (effusive activity)
SO2 is a magmatic gas which forms at large depth, which may be
indicative of the relative
evolution of gas volume and gas flux
The critical gas flux in reservoir, determined from fire fountain
height, is approximatively
50 kg/s at Kilauea volcano
SO2 is easily
measured at the
vent (mass
spectometer:
Cospec, FTIR…)
