    Pyroclastic Flow

    Pyroclastic flow is high density of hot dry rock fragments and glass that move away from a vent that erupted them. May result in molten or solid rock fragments or even both.


    Effects of Pyroclastic Flow

    Pyroclastic flow will destroy almost everything in it's path. Fragment sizes range from ash to the size of a boulder rolling down the a mountain at speeds up to 80 km per hour(49mph). The extreme temperatures of the rocks inside of Pyroclastic flow usually are between 200°C to 700°C (392°F to 1292°F).
