poured from the gap for a considerable time afterwards. The area of extreme damage extended over a radius of about 12 km, while people near Higaturu, 14 km from the volcano, were killed by the blast or burned to death. The pyroclastic flows and subsequent eruptions of dust and ash which filled streams and tanks, caused the death of some 3,000 people, and considerable damage. More than 5,000 people were made homeless.One figure for total number of deaths is 3,466 people, see . Rescue parties which arrived on the scene were hampered by suffocating

was threatened with destruction by other eruptions during the several days following. Further tremors and explosions occurred during February. As late as 5 March a major eruption occurred which threw large pieces of the volcanic dome as far as three kilometers and caused a flow of pumice and rocks for a distance of 14 km, the whole time being so hot as to set fire to every tree in its path. The pyroclastic flow created from this eruption destroyed about 200 square kilometers of land.
