Pyroclastic flows from Unzen were generated by gravitational collapse of the growing lava dome, near the city of Shimabara, Nagasaki (1991). Most of the flows traveled from 1 to 3 km, but some flows reached more than 4 km, burning houses and killing people in the evacuated zone of Kita-kamikoba on the eastern foot of the volcano.The velocities of the flows ranged from 15 to 25 m/s on the gentle middle flank.
