Chile's Calbuco volcano erupts

SANTIAGO, April 22 (Reuters) - Volcano Calbuco in southern Chile erupted for the first time in more than five decades on Wednesday, sending a thick plume of ash and smoke nearly 20 kilometers into the sky.

Calbuco had another spectacular outburst early today, lightning crackling through a dark sky lit orange-red by the explosion. As the ash cloud spread, "people went into a state of panic," said Miguel Silva Diaz, 28, an engineer who lives about 14 miles from the volcano.
