Fume rises from spatter cones

Fume rises from spatter cones and pits on the floor of Pu`u `O`o crater. The most active of these is the East Pond Vent, the crucible-shaped cone at the left end of the crater. The East Pond Vent is surrounded by a rumpled skirt of pahoehoe, which poured from the vent in February 2005. The crater is 400 m (1,300 feet) long. View is to the south.
