Three volcano eruptions in southwest Colombia sent smoke and ash into the sky and prompted Colombian authorities to declare a red alert in the area.

Authorities believe a larger eruption is imminent from the 14,000 foot Galeras volcano.

It's located about 12 miles southwest of the town of Pasto.

The volcano began spewing ashes Sunday and authorities have declared much of the surrounding area off limits.

No evacuations have been ordered as yet.
