Sabancaya- recapitulative table of activity between March 25 and 31, 2019 - Doc. IG Peru / OVI / Ingemmet

During the last week of March, Sabancaya's eruptive activity remained at a moderate level, with an average of 43 explosions per day, accompanied by gas and ash plumes rising up to 1,500 meters above the crater, and a dispersion over 30 km. in an east and south-west sector.

Sulfur dioxide emissions remain high at 3,000 tonnes / day, measured on March 31st. A thermal anomaly of VRP 24 MW was recorded by Mirova.

Seismicity is dominated by LP earthquakes, associated with fluid movements, and hybrid earthquakes, that are few in number and low in energy, in connection with the rise of the magma.
