Sabancaya - ash emissions on 16.03.2018 / 8:47 - webcam IGP

Sabancaya was the site of continuous ash emissions on March 16, 2018, from 8:43 local.

The plume rose to 2,500 meters above the crater, and dispersed over a maximum of 30 km to the northwest.

The ashfall affected five areas, Huambo, Cabanaconde, Pinchollo, Maca and Tapay. IG Peru recalls measures to protect the respiratory tract, eyes and water reserves.

On 16 March, a control flyby of Popocatépetl was carried out with the assistance of the Federal Police.

The internal crater retains its dimensions: diameter 320 meters and depth about 100 meters.

A dome, No. 78, nestles there, with a diameter of 50 meters and 30 meters thick. The walls of the inner crater retain traces of the earlier domes.

Gas emissions mark the new dome, growing and likely to be the seat of future explosions.

Alert level remains at Amarillo fase 2.

A small explosion was noticed by seismic and infrasonic surveillance systems on March 15 at 6:19 UTC in Cleveland. It was not preceded by local earthquakes.

No clouds of ash were observed by the satellites.

A future explosive activity is possible without warning signs, and the level of the volcanic alert remains Advisory and the yellow aviation code.
