UPDATE 8:00 PM (Eastern): It looks like Bariloche is being heaviest hit by the ash from the eruption - looks like a lot of ash on the ground in the resort town. You can see more of the ash fall images here as well. The Chilean government is evacuating over 3,500 people from the region near the volcano and also closed a border crossing between Chile and Argentina. Some incandescence was spotted at the summit of the volcano as well. Eruptions reader Miguel posted this great animated GIF showing the ash plume from Puyehue-Cordón Caulle spreading to the east. Eruptions reader Raving posted a great clipped version of the NASA Aqua satellite image the eruption (see below), showing the tan plume towering over the lower white clouds.
