Based on seismicity detected during 6-13 March, OVDAS-SERNAGEOMIN reported that the eruption from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, continued at a low level. Plumes observed most days in web camera and satellite images rose 0.3-1.2 km above the crater and drifted 30-50 km NNE, E, and SW. Incandescence from the crater was observed during 5-8 and 10-13 March. The Alert Level remained at Red. ...more [read all]

The eruption from the Cordón Caulle rift zone, part of the Puyehue-Cordón Caulle volcanic complex, continued at a low level. During 28-29 February plumes observed with a web camera and satellite images rose 1 km above the crater and drifted 40 km NNE. During 2-3 March plumes rose 0.7-3 km above the crater and drifted SE. ...more [read all]

The eruption from the Cordón Caulle rift zone continued at a low level. A lava flow reached the valley of the Nilahue River, and 2 lava flows advanced to the N margin of the W crater. ...more [read all]

The eruption continues at a low level. During 14-16 and 20-21 February plumes observed with a web camera rose 1 km above the crater; clouds prevented views during 17-19 February. Satellite images showed ash plumes drifting 12-180 km NE, ENE, SE, and ESE during 14-15 and 18-21 February. Clouds prevented views from satellite during 16-17 February. Crater incandescence was observed during 14-15 February. The Alert Level remained at Red. ...more [read all]

Nearly 2 months after its start, the explosive and effusive eruption from Chile’s Puyehue-Cordón Caulle Volcanic Complex is still continuing, but on a much lower level than during the first month of the eruption. In recent days, the eruption column has been reaching up to 2 km and producing ash plumes drifting east into Argentinia where the ash is causing problems to infrastructure, as well as disruption to air traffic. ...more [read all]

The eruption of Puyehue Cordon-Caulle has decreased in intensity, although near continuous ash emissions are still going on. In its latest bulletin on Friday, SERNAGEOMIN reports the height of the ash column did not exceed 3 km, and the plume is drifting at flight level 200 (20,000 ft / ca. 6 km) altitude into Argentina, where the ash fall has become a major problem in several towns and villages near the border, in particular in and around Bariloche. Electricity and water supply have become damaged, impacting the tourist industry severely. As well, faramin, especially of sheep, is suffering heavy losses. [read all]

The eruption at Puyehue-Cordón Caulle continues to be big. In its latest bulletin, SERNAGEOMIN reports that a dense pulsating column of ash is erupted and reaches up to 9 km altitude, corresponding to strongly fluctuating levels of tremor. At night, the lower 1.5-2 km of the column show incandescence. The eruption column produces a visible plume of 250 km length to the SE where heavy ashfall occurs. Further apart, in Argentinia and across the globe in Australia and New Zealand, the ash plume which is now circling around the southern hemisphere continues to cause serious disruption of air traffic.

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: ...more [read all]

The eruption at Puyehue volcano shows no signs of exhaustion. While the plume had decreased significantly after the initial eruptions, the eruption has increased again in the past days and the volcano is now producing a near-constant ash column which reaching 4 to up to 10 km altitude and drifting east (VAAC Buenos Aires). ...more [read all]

The eruption at Puyahue volcano has weakened a lot in the past days. As of today, 10 June, the volcano continues to erupt, but the ash cloud reaches "only" 15,000 ft (ca. 5 km) altitude, compared to >10 km in the previous days. (VAAC Buenos Aires) [read all]

The eruption at Puyehus volcano has decreased, but the volcano continues to emit an impressive ash plume, but there is still a lot of ash in the atmosphere above a large swath of Argentina, causing a hazard for flight operations. ...more [read all]

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. [read all]

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. ...more [read all]

A significant eruption is taking place at Puyehue-Cordón Caulle volcano in central Chile. The eruption started on 4 June with a large explosion that sent an ash plume to 10 km altitude (FL350, 35,000 feet a.s.l.) which was moving towards SE into Argentina. More than 3500 people have been evacuated. ...more [read all]
