The Mayon Volcano in the Philippines began to rumble again on Saturday, spewing a cloud of ash and debris into the sky. The eruption caused heavy ash fall, blanketing parts of Albay Province and darkening the sky in several areas.

The 2,462-meter volcano is one of the Philippines' top tourism draws because of its near-perfect cone shape. But it's also the most active of the country's 24 restive volcanoes.
