Chile's Calbuco volcano erupted on Wednesday, spewing a giant funnel of ash high into the sky over a sparsely populated, mountainous area, triggering a red alert. Authorities ordered an evacuation for a 10-kilometer (six-mile) radius around the volcano. Calbuco is the second volcano 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.
