Vegetable growers in the highlands of Cartago and Turrialba are concerned that if the Turrialba volcano ash continue falling on their fields the losses would be significant, according to local media. The Turrialba volcano began erupting Monday afternoon, spewing thick black clouds of ash more than 8,200 feet (2,500 meters) into the sky. REUTERS/Juan Carlos Ulate
