`A`a flow on Pulama pali, Kilauea Volcano, Hawai`i
Photographs by D.A. Swanson on February 24, 2000

`A`a flow on Pulama pali, Kilauea Volcano, Hawai`i Leading edge of the same `a`a flow; pieces of broken crust are tumbling from the front, exposing the molten interior.

This `a`a flow originated from a breakout of lava tube 200-300 m upslope on Pulama pali. The breakout initially formed a pahoehoe flow. As the pahoehoe sped down the steep slope of the pali, it transformed into `a`a. When the photographs were taken, the front of the `a`a was advancing at a rate of 1 m per minute or faster, burning and bulldozing its way through the bordering `ohi`a forest.
