Despite being classified as a “minor” (menor, in Spanish) eruption, Chile’s Puyehue Cordón-Caulle Volcano continues to pump out large amounts of ash. This natural-color satellite image shows the pale plume blowing to the northeast of the active vent. According to SERNAGEOMIN, the Chilean National Service of Geology and Mining, ash rose to a height of 5 kilometers (3 miles), and blew as far as 300 km (190 miles) from the volcano. Wide-area satellite images show the full length of the plume, and ash covering the Argentinian plains to the east of Puyehue Cordón-Caulle.
