Photograph by J.D. Griggs on October 23, 1986

Pu`u `O`o as it looked after the last high fountaining episode in 1986. The conduit, marked by a small spatter cone and gas plume, is about 15 m across.

Photograph by T. Mattox on August 30, 1990

The Pu`u `O`o conduit began to collapse in mid-1987. By the time of this photograph in 1990, the crater was roughly 300 m long by 200 m wide. Lava was intermittently visible at the bottom of the crater during this time. Here lava rises on the uprift side of the crater (right), streams across the crater floor, and pours down a hole at the other end.
