The Pleistocene Lanai shield volcano was constructed along three rift zones, the most prominent of which is the NW rift zone. The large submarine Clark debris avalanche extended 150 km S (Moore et al. 1989). A caldera is located at the southern end of the island. Lava and spatter cones were formed along the rift zones. A single Potassium-Argon date of 1.28 +/- 0.4 million years ago has been obtained on Lanai basalts.
