USA Hawaii map Karte Oahu Island Koolau Range

Koolau Range is a mountain range in Honolulu County. The state capital Honolulu is located on the southeast coast of the island Oahu. 

The island is formed by two old eroded shield volcanoes, the Koolau and Waianae. The highest point of Oahu island is Mount Kaala (1’220 m) in the Waianae Range. The last eruption of Waianae is more than 2.5 million years ago.

Konahuanui (946 m) is the highest point of the Koolau. Koolau is about 37 miles long and makes up two thirds of the island of Oahu. Koolau mountain forms Oahu's windward coast and rises behind the leeward coast city of Honolulu. The volcano became dormant about 1.7 million years ago, but became active again hundreds of thousands of years later. 

There have been around 30 eruptions in the last 500,000 years, creating some of Oahu's famous landmarks, such as Koko Head, Hanauma Bay, Punchbowl Crater and Diamond Head. Geologists believe there is a remote possibility that Koolau will erupt again.
