Wind-Blown Ash from Puyehue-Cordón Caulle
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
In late January 2013, ash again fell on communities downwind of Puyehue-Cordón Caulle. But rather than signaling the onset of a new eruption, the ash was the result of dry weather and high winds in the Andes Mountains, according to the website barilocheopina.com. Fine ash was picked up by the wind and carried over 150 kilometers (93 miles) from the volcano. Ash extends to Chile’s Pacific coast in this natural-color satellite image. The image was collected by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on January 20, 2013.
