The Tungurahua volcano, 85 miles south of Quito, Ecuador erupts at about 5:50 a.m. Sunday, July 16, 2006. Thousands of villagers have fled their homes on the slopes of the volcano since it began erupting lava and toxic gases, authorities said Saturday. No injuries have been reported, but some 3,700 people have abandoned their homes in half a dozen hamlets since Friday, the Civil Defense said. In May, the volcano, began emitting its loudest and most frequent explosions since it rumbled back to life nearly seven years ago after being inactive for eight decades. (AP Photo/Cecilia Puebla)
