CHILE-VOLCANO-VILLARRICA

Police control the access to the Villarrica volcano, in Pucon, some 800 km south of Santiago, showing no visible signs of activity on March 5, 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. Chile keeps the red alert two days after the Villarrica volcano erupted but reduced the risk area from 10 to 5 km.
