Similar explosive activity, with increasing tendency, had already been occurring during the previous days, in particular since Sunday. Very strong explosions also occurred yesterday afternoon at 16:28 local time, two around noon (also yesterday), as well as at 19:35 and 05:35 local time on Sunday (6 March). All of them produced pyroclastic flows into various directions towards the western (Romero and Achupashal) and northern sectors (Mandur).
Violent shock waves that rattled windows and doors and ground rumblings accompanied the explosions and most of the time, a steam and ash column was rising 3-4 km from the volcano. At night, explosions could be seen ejecting incandescent material to great height (many 100 meters) and distances over the volcano's cone, generating spectacular avalanches.
Considerable ash fall has been affecting various areas around the volcano. In particular, the western sectors have suffered most. A team of IGEPN scientists measured a load of 7700 g/m2 of ash had accumulated since the end of February in the areas of Manzano and Choglontus. The area is rich in corn fields which have been severely damaged by the ongoing eruption.

The activity of the volcano has increased during the past days. Near-continuous explosive eruptions at the summit crater have been creating ash plumes that rose up to 3 km and drifted into westerly directions. Up to 2 mm of fresh ash fall occurred in areas up to 10-20 km west of the volcano. Incandescent bombs were seen ejected during the explosions as well. ... [more]
