1997 fumarole temperature measurements
In December 1997 scientists measured fumarole tempratures of 220 deg C in the crater of El Misti volcano.April 1984 gas emissions
In early April 1984, gas and steam emissions increased at the crater of El Misti, creating a plume of 1 km height. Scientists who tried to collect samples on 29 April were prevented by doing so due to the high levels of irritating gasses (SO2 ?).1985: new fumaroles
On 7 and 8 August 1985 geologists observed vigorous new fumaroles on the N side inside El Misti's crater. Highly pressurized gasses escaped with lots of noise from 6 new vents and red (liquid?) and yellow (solid) sulphur deposits were observed in and around the vents.(USGS/GVP monthly reports)
