A Smoking Vent

Pu'u 'O'o fountain, approximately 450 m high, produces clouds of black cinder that are carried downwind (southwest) of the vent. Low fountains play from fissure at base of cone. View is from northeast, at Pu'u Halulu. Pu'u 'O'o gained 12 m in height during episode 25. By the end of October 1984, Pu'u 'O'o's height was 155 m above the pre-1983 surface (photo by C.C.
