Puyehue-Cordón Caulle volcano (Chile), eruption update: continuing ash emissions

NASA Earth Obseervatory image of Puyehue volcano on 31 July 2011. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image on July 31, 2011. A pale ash plume rises above erupting fissures, then fans out toward the north and east. The plume casts a shadow over the lava flow along the western (left) edge of the image. To the south of the plume, areas that have not been coated with lava sport instead a dendritic pattern of white snow and brown ash. (Source: http://earthobservatory.nasa.gov/IOTD/view.php?id=51541)

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.
The lava emission from the eruptive fissure seems to have ended.

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. [more]

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]

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). ...

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) [more]
