Two days of continuous emissions at the Puyehue-Cordón Caulle Volcanic Complex have created an ash plume the extends more than 1,000 nautical miles (1,900 kilometers): from Chile, over the coast of Argentina, and out into the Atlantic Ocean. Puyehue-Cordón Caulle began erupting on June 4, 2011, emitting ash to a maximum altitude of 45,000 feet (14,000 meters), according to the Buenos Aires Volcanic Ash Advisory Center (VAAC). The ash plume remained at or above 40,000 feet (12,000) for at least the next two days. This image combines visible and infrared imagery from the Geostationary Operational Environmental Satellite-East (GOES-East) with color imagery from the Moderate Resolution Imaging Spectroradiometer (MODIS). A complementary animation shows the evolution of the plume from 1:45 p.m. local time June 4, 2011, until 10:45 a.m. June 6, 2011.
