No one saw this coming. The volcano had been quiet for the last 42 years before erupting twice in the span of a few hours, all with just 15 minutes of warning beforehand. Some 4,000 residents in the nearby town of Puerto Montt and surrounding areas were evacuated. Fortunately, no one was hurt.
Nothing breaks up the day like an unexpected volcanic eruption. On April 22, Calbuco in southern Chile erupted in dramatic fashion - sending a massive plume of ash more than 12 miles into the air.
One of the largest historical eruptions in southern Chile took place from Calbuco in 1893-1894.
