Background
The uninhabited island of Kahoolawe, SW of the island of Maui, consists of a broad, low basaltic shield volcano formed by Pleistocene eruptions along a rift zone that extends SW from a buried, 5-km-wide caldera at the eastern side of the island. The eastern rim of the caldera lies beneath the waters of Kanapou Bay. Two less prominent rift zones trend to the east and north. Much of the island is truncated by steep sea cliffs that expose the thin lava flows making up the volcano. Stearns (1946) and Macdonald and Abbott (1970) considered cinder cones within the caldera on the west side of Kanapou Bay to be of Holocene age, but this age was considered probably too young by Langenheim and Clague (1987), who mapped the cones as Pleistocene or Holocene. Sano et al. (2006) obtained K-Ar dates on the youngest flows of 900,000 to 980,000 years Before Present.---
