Today, 30 miles south of Quito, Cotopaxi—a volcano that first erupted in 1534, but has been quiet since the early 1940s until a few recent months of unrest—spewed plumes of ash and vapor. Though the blasts spread gray powder across the area, scientists in Ecuador do not believe a major eruption is imminent.
