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.
