A new fissure, and a single vent offset 30 m to the southeast, broke through the tephra-covered south flank of Pu`u `O`o on
the evening of October 2, 1992. The new vents marked the beginning of episode 52. Fountains
quickly built a line of spatter cones along the 65-m-long fissure. The new
fissure was active for two weeks.
Top: Aerial view of the new offset vent (prominent lava
fountain) and fissure (fuming area behind vent) on
the south flank of Pu`u `O`o (whose slope is on right). The offset vent was the most
active, with lava fountains 5-8 m high.
Bottom: View is toward the south from the tephra-covered slope of
Pu`u `O`o. Lava erupted from the episode-52 fissure built several spatter
cones and flowed south about 3 km to the brink of Pulama pali.
