Calbuco's Eruption Spews Thick Plume of Ash

Calbuco’s April 22 eruption sent ash billowing 12 miles into the sky over Chile’s Llianquihue National Reserve. The ash cloud has blown into Argentina, darkening the skies and dropping a thick layer. This footage was shot from Puerto Montt as the volcano exploded. Credit: YouTube/Felipe Colihueque Brevis
