Spokeswoman Mercedes Taipe of Ecuador’s Geophysics Institute says a column of vapor and ash up to 2.5 miles (4 kilometers) high has characterized the moderate-to-strong eruption.
She said Tuesday that a half-dozen villages are being showered in ash. She had no immediate estimate on economic damage to local farming.
The 16,48-foot (5,023-meter) volcano 84 miles (135 kilometers) southeast of Quito has been active since 1999. In July and August of 2006 eruptions of Tungurahua killed at least four people, left two missing and forced the evacuation of thousands.
