OAVV-SEGEMAR volcano cams

The Observatorio Argentino de Vigilancia Volcánica is part of SEGEMAR, the national geological and mining survey, and it is the body responsible for watching Argentina's volcanoes. It covers ten of them: Copahue, Domuyo, Lanín, Laguna del Maule, Planchón-Peteroa, Tromen, Tupungatito, Maipo, San José and, a long way south, Deception Island in Antarctica.

Almost all of those sit on the border with Chile, which is the defining fact of the observatory's work. The volcanoes themselves are usually watched from both sides, and an eruption on the Chilean crest sends its ash east over Neuquén and Mendoza — so Argentina monitors mountains whose summits are not in Argentina at all.

Its cameras publish a new image every few minutes, with the station name and the time stamped into the picture, and the observatory also publishes alert levels and regular reports. The stations are named in three letters, which is what the camera names on this site refer to: AGS and AER at Copahue, EMA at Domuyo, AAL at Lanín, LAG at Laguna del Maule.

Not every camera is running at once — the sites are remote and some have been out of service for months at a time — so the ones shown here are those that were checked and working.
