Kohala

Kohala is the smallest volcano of the island and last erupted 60,000 years ago. Because of the long interval since the last eruption, geologists think that Kohala is probably extinct. Kohala is in the erosional stage.

The northeast side of the volcano is deeply dissected, producing scenic valleys, like the famous Waipio Valley. This aerial view shows the steep walls and flat floor of the valley. The landslide at the base if the sea cliff probably occurred during the magnitude 7.9 earthquake in 1868. Photography courtesy of Jack Lockwood, U.S. Geological Survey.
