A volcano that destroyed an entire town in Colombia with the death of some 25,000 people spewed ash and gas this weekend on the 36th anniversary of that devastating eruption, AFP reported.
The Nevado del Ruiz volcano showed "noticeable" activity starting Saturday, the Colombian Geological Service said.
In late 1985, after decades lying dormant, this one began to rumble.
And on November 13 it erupted, emitting so much heat that it melted the snow that caps the mountain permanently.
