The eruption at Puyehue-Cordón Caulle is still going strong, producing a pulsating 4-8 km high column of ash and incandescent material visible at night at the base of the eruption column. The Volcanism Blog has posted a great summary of the latest two reports of SERNAGEOMIN from 11 and 12 June. The key points are:
- It is confirmed that the vent of the oingoing eruption is a new fissure at the head of Nilahue river and immediately north of the 1960 eruptive fissure.
- The height of the ash column varies considerably and changes in short time. During pulses of stronger activity, the plume reaches up to 8 km, ballistic blocks reach up to 1 km distance and small column collapses (generating pyroclastic flows ?) were observed at the base of the column.
- A new cone has been built at the vent, with a 300-400 m wide new crater.
- Significant amounts of ash have accumulated east of the volcano, and floating pumice is observed on Maihue, Huishue, Gris and Puyehue lakes. No fresh ash is found on the south-western part of Cordón Caulle and the western slopes.
- The fresh ash around the volcano poses a significant hazard of lahars during strong rains.

The intensity of the eruption continues at more or less the same level as yesterday. A sustained column of ash rises from the Caulle vent area to 10-12 km altitude, drifting NE. The ash affects many regional flights within Argentina as well between Argentina and Chile, many of which have been cancelled. Flights within Chile so far seem to be operating normally. ... Lees alle

The spectacular explosive eruption at Puyehue volcano continues, although its intensity seems to have decreased slightly. It is producing a sustained column of ash that reaches 10-12 km altitude and is currently drifting NE. Significant ash fall is occurring SE, E and NE of the volcano including the province of Río Negro, Argentina, with the popular resort town of Bariloche, where heavy ash fall is reported and causing problems to daily life and infrastructure. ...
