Lecture on Pyroclastic Flow

Prime purpose of this lecture is to present on Pyroclastic Flow. Pyroclastic Flow is a dense, destructive mass of very hot ash, lava fragments, and gases ejected explosively from a volcano and typically flowing at great speed. A famous historic example of an explosive eruption that produced devastating pyroclastic flows was the 79AD eruption of Mt Vesuvius in Italy that buried the ancient Roman city of Pompei. For example, eruption of Vesuvius in 79 AD destroyed the city of Pompeii.
