An eruption began in Turrialba on September 30 at around 10 pm and continued on October 1, with the emission of a plume of ash of variable shape between 300 and 500 meters above the active crater (depending on the source). These ashes dispersed to the northeast of the volcano.

Activity Summary of Sabancaya between September 24 and 30, 2018 - Doc .IG Peru

In the last week of September, Sabancaya's eruptive activity remained at a moderate level, with an average of 21 explosions per day; they were accompanied by ash plumes at a maximum height of 3,700 meters above the crater and a dispersion towards the south, within a radius of 50 km. Hybrid earthquakes, related to the rise of the magma, remain low in number and energy.

Sulfur dioxide flows remain high, with a maximum of 3,250 tonnes per day on 29 September.

Six thermal anomalies, between 3 and 20 MW, were recorded by Mirova.

Surface deformations do not show significant variations

Bilan in images "before & after" of the damage caused by the last eruption of Kilauea in the East rift zone, and especially in the urbanized areas of Leilani Estates, Lanipula gardens, Kapoho beach lots and Vacationland.

All parameters remain low under continued HVO monitoring.
