The Costa Rican authorities suspended operations at the country's main airport Monday after the nearby Turrialba volcano erupted, sending a thick ash cloud into the sky. Turrialba erupted twice Monday, first at dawn and again just before noon. The second eruption sent an ash cloud 4,000 meters (13,000 feet) into the air. / AFP PHOTO / Ezequiel Becerra
