Authorities in the southern Colombian department of Nariño are on high
alert after the Galeras volcano became active and blew smoke one and a
half mile up in the sky.
The Galeras is one of the volcanoes of the so called “Pacific Ring of Fire”, has a height of 4,275 meters and is one of Colombia’s fifteen active volcanoes.
The volcano erupted a dozen times since 1989. The last time was in January when surrounding towns and villages had to be evacuated.
