It moved ash further than had been predicted. Both Clark Air Base and Subic Bay Naval Station were heavily damaged by ash from this eruption, the second largest terrestrial eruption of the twentieth century. The last eruptions registered are in 1985, 2012, and 2014 for the Colombian volcano and in 1992, 1992, and 1993 for the Philippine one [8][9]. Those functions are the backbone of CDCs mission.
