Photo Friday: Monitoring Chile’s Volcanoes

Currently, three volcanoes in Chile are restless, according to the Servicio Nacional de Geología y Minería. A “class yellow” status for these glacier-covered peaks means elevated seismic activity and higher potential for eruption.

The ice caps on these giants mean that an eruption could spur Jökulhlaups, glacial outburst floods that can be extremely dangerous, such as in the 2010 eruption of Iceland’s Eyjafjallajokull.

Will all three Chilean volcanoes erupt, or none? Which will erupt first? Monitor the situation from home by watching their webcams.
