Blowholes in Hawaii
In this publication are listed 15 locations with blowholes in Hawaii Islands – not only the famous Halona and Nakalele blowholes but also many that are lesser-known, such as the amazing Moku Aeae blowhole. The geology of Hawaii is suitable for these geological formations because there are lots of suitable materials – these volcanic islands have much recent lava flows that have reached the sea.
