CHILE-VOLCANO-VILLARRICA

A Chilean national flag is seen with the Villarrica volcano in the background, near Villarrica in southern Chile, showing no visible signs of activity just a couple of hours after it erupted on March 3, 2015. The Villarrica erupted early Tuesday, spewing fiery plumes of lava into the night sky and forcing the evacuation of some 3,600 people in nearby towns. In its first major eruption in 15 years, the Villarrica volcano, prompted authorities to declare a red alert, the National Emergency Office said. But within about seven hours the eruption calmed, and there were no longer any visible signs of activity.
