Those Chaitén webcams: a reminder 16 February 2010

We’re overdue for a Chaitén update here at The Volcanism Blog. I hope to be able to publish a Chaitén post tomorrow or on Thursday (a busy couple of days lie ahead for me, hence the vagueness of this schedule).

In the meantime, here’s a reminder of where to find webcam images of Chaitén. There are now two cameras, our old friend the DGAC (Chilean Civil Aviation Directorate) camera at Chaitén airfield, and the new OVDAS (Observatorio Volcanológico de los Andes del Sur) camera overlooking the caldera. The latter was installed very recently and lots of people seem to be unaware of it (although a post about it was published here earlier this month, thanks to tip-offs from our friends Guillermo and Boris Behncke). The new camera gives a very good close-up view of the Chaitén caldera.

Links to the Chaitén webcams:

OVDAS camera at Chaitén caldera

OVDAS now has several webcams offering views of notable Chilean volcanoes. They can be accessed via the front page of the shocking OVDAS website, or, conveniently, from this earlier Volcanism Blog post.

New OVDAS webcam for Chaitén 4 February 2010

Webcams have been proliferating of late at the Observatorio Volcanológico de los Andes del Sur (OVDAS) in Chile: nine are now linked from the main page of the OVDAS website. The latest addition is a new webcam for Chaitén, giving a view of the caldera, with an image that updates every 10 seconds or so. At the moment it’s the early hours of the morning in southern Chile and the camera shows only darkness, so I can’t say anything about what the image is like or even if it is actually working or not. Anyway, here’s the link:

The two most recent Chaitén bulletins from SERNAGEOMIN to be made publicly available (via the SEGEMAR website and at Werner Luis’s Chaitén site) are no. 111 covering 14 November to 1 December 2009 (PDF) and no. 112 covering 1-15 December 2009 (PDF). Translations as follows.

CHAITÉN VOLCANO
TECHNICAL BULLETIN NO. 111
14 NOVEMBER TO 1 DECEMBER 2009
OVDAS-SERNAGEOMIN

1. Visual monitoring

The area of Chaitén volcano has remained covered by cloud for most of this period, because of the poor weather conditions. Nevertheless, OVDAS personnel based in the area were able to observe an increase in fumarolic activity on 18 November characterized by a column of some 3,000 m altitude, principally composed of water vapour (Fig. 1). This activity was related to rumbling sounds and a slight increase in seismicity recorded on that day.

Moreover, on 22 November the DGAC camera recorded a vigorous emission of steam, gases and ash with an altitude not surpassing 1000 m above the dome complex (Fig. 2).
