A small pyroclastic flow descends the Bonga valley on the E flank of Mayon in March 1993. Collapse of a lava flow front traveling down the valley produced many small pyroclastic flows during the 1993 eruption. A large pyroclastic flow on 2 February, the first day of the eruption, traveled 6 km down this same valley and killed 75 people.
