The volcano has a few periods of up to 20+ years of silence - but Mayon volcano often has periods of frequent almost annual volcanic activities - from 2000 till todate 7 activity periods. Hence Mt. Mayon volcano certainly is a live volcano and had repeatedly disastrous eruptions with numerous casualties and destruction of larger areas due to lava flow, lahar, ashes, etc. with up to 17 km high eruption column. The most fatal eruption was on February 1, 1814 and buried the entire town of Cagsawa - see the photo album from the Cagsawa ruins for more details.
