.Puyehue położony jest 870 km na południe od stolicy Santiago w kompleksie Caulle Cordon położonym w Andach. Jego ostatnia większa erupcja w roku 1960, poprzedzała trzęsienie ziemi o magnitudzie 9.5 w skali Richtera

The eruption continues at Puyehue-Cordón Caulle: the overall picture appears to be of a stable situation of continuing activity with a slight tendency to decline; within this overall picture there is slight variability in the intensity of the eruption. SERNAGEOMIN’s bulletins (accessible as PDFs here) generally report slight reductions in seismic activity from day to day, although the bulletin for 9 June (PDF, or online) reported a slight increase compared with the previous day. The most recent bulletin (10 June 2011: PDF, or online) reports a slight decline in seismic activity and a continuation of tremor associated with the process of degasification, also consistent with previous days. The eruption column is not currently visible because of poor weather conditions, but the bulletin gives its altitude as approximately 3.7 km, with the plume directed towards the SE, with prediction of continuing ashfall ‘towards the ESE’. Using satellite data, the bulletin also gives a location for the seat of the eruption: ‘New satellite images from the TerraSAR X satellite allow centre of emission of the eruption to be located more precisely. The location has been determined to be in the Los Baños area, at the headwaters of the río Nilahue, at co-ordinates 40.525º S, 72.142º W’. This puts the activity on the south flank of Puyehue-Cordón Caulle, about 7.5 km from the summit.
The bulletin warns that ‘given the stability of the eruptive activity’ there is the likelihood of ‘continuing occurrence of waves of pyroclastic flows along the course of the Nilahue river, the waters of which may reach temperatures similar to those reported yesterday [45°]‘, and that ‘the heavy rain occurring in the region, along with the great accumulation of pyroclastic material (ash, pumice, flows) in the headwaters of the watercourses which originate in the volcanic complex, favour the probability of the occurrence of secondary lahars generated by the blocking of the stream beds’. The accumulation of ash across a wide area to the SE of the volcano is expected to cause continuing problems of floods and lahars for as long as the eruption continues. The bulletin ends by stressing that despite the eruption’s tendency towards stability there remains the possibility of an upswing in activity, and thus that the alert level of Red 6 – Moderate Eruption is being maintained.
