People watch from Puerto Varas, southern Chile, a high column of ash and lava spewing from the Calbuco volcano, on April 22, 2015. Chile's Calbuco volcano erupted on Wednesday, spewing a giant funnel of ash high into the sky near the southern port city of Puerto Montt and triggering a red alert. Authorities ordered an evacuation for a 10-kilometer (six-mile) radius around the volcano, which is the second in southern Chile to have a substantial eruption since March 3, when the Villarrica volcano emitted a brief but fiery burst of ash and lava.
