Aerial video captures volcano eruption in Colombia

STORY: The video captured smoke and ash spewing out of the crater, as well as an eruption that lit it up.

The Colombian Geological Service (SGC) has reported a significant increase in seismic activity associated with rock fracturing within the volcanic structure since March.

Nevado del Ruiz is one of the region's deadliest volcanos. In 1985 an eruption buried entire settlements and killed more than 25,000 people. It is Colombia's biggest natural disaster.
