Spectacular eruption of Villarrica volcano in southern Chile sends thousands fleeing

One of South America’s most active volcanoes has erupted in southern Chile, spewing heavy smoke into the air as lava surged down its slopes, prompting authorities to evacuate thousands of people.
The Villarrica volcano erupted around 3 am Tuesday local time, according to the National Emergency Office, which issued a red alert and ordered evacuations. Local media showed images of the volcano bursting at the top, glowing in the dark amid heavy smoke and rivers of lava.
Authorities worried that mudslides caused by melting snow could endanger nearby communities, but no injuries were reported.
