A volcano in Colombia has erupted, forcing authorities to evacuate thousands of people.

No injuries are reported from the Galaras volcano in southwestern Colombia, not far from the border with Ecuador.

The volcano started erupting Thursday night and spewed ash over a large area. Witnesses say the eruption lit up the night sky for several hours.

Colombian officials evacuated 8,000 people from nearby villages and the city of Pasto.

The Galaras volcano last erupted in 1993, killing nine people.

The 4,000 meter high volcano is located in Colombia's Narino region.
