El Misti volcano from satellite on 5 March (image: Sentinel 2)
Monday, Mar 16, 2020
IGP reported that the warning system at the volcano detected the decrease of a lahar (volcanic mud flow) of a low to moderate volume that traveled downslope in SE direction due to the streams that run through this sector. ... [details]
The report of IGP showing the signals of the seismic swarm at EL Misti volcano in Peru
Friday, Jan 17, 2014
The volcano experienced an earthquake swarm during 14-15 January, IGP reported in its latest bulletin. An increase of approx. 25% in seismic activity overall with respect to last year's average was calculated, but IGP stresses that this activity is still low and does not suggest new activity in a near future. ...

El Misti volcan éruptions

stratovolcan 5822 m / 19,101 ft
Peru, -16.29°S / -71.41°W
Liste des éruptions: 1985(?), 1870(?), 1869(?), 1831(?), 1830(?), 1826(?), 1787, 1784, 1677, 1599(?), 1542(?), 1454 ± 16, 1350 ± 50, 760 AD ± 100, 90 AD ± 300, 80 BC ± 75, 310 BC ± 100, 2230 BC ± 200, 3510 BC ± 150, 4020 BC ± 200, 5390 BC ± 75, 7190 BC ± 150


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)

1971 gas emissions
Elevated gas and steam emissions occurred from the crater of El Misti volcano in 1971.

1949: new fumaroles
New fumarolic activity resumed in El Misti's crater in 1949.

310 BC (sub)plinian eruption
The last major eruption of El Misti was about 2000-2300 years ago. It deposited a significant pumice layer which is 30 cm thick at 13 km distance from the volcano and extends 25 km SW. A similar event today would be a major hazard for the city of Arequipa.
