Dozens of towns dusted with ash from Ecuador's Tungurahua volcano
Volcano monitors say about a dozen farming villages have been dusted with ash due to bursts from Ecuador's Tungurahua volcano.
The Geophysics Institute says clouds of gas and ash have risen as high as 2,500 meters (8200 feet) above the crater, producing "a strong fall of dark gray ash" over some settlements.
Thursday's report comes a day after authorities imposed new precautionary measures around the volcano, which has been increasingly restive.
The 5,023-meter (16,480-foot) volcano is located about 140 kilometers (85 miles) south of the capital, Quito, and close to the tourist city of Banos.
