FILE - In this Dec. 23, 2009 file photo, a column of ash shoots up to the sky in a mild eruption of the cloud-covered Mayon volcano as viewed from Legazpi city in Albay province, 500 kilometers southeast of Manila, Philippines. The volcano spewed huge rocks and ash early Tuesday, May 7, 2013 after a 3-year calm, killing four climbers and trapping others near the crater, officials said. (AP Photo/Bullit Marquez, File) less
