Hawaii Volcanoes National Park contains Mauna Loa and Kilauea, two of the world’s most active, understood and accessible volcanoes where ongoing geological processes are easily observed. This property serves as an excellent example of island building through volcanic processes. Through the process of shield-building volcanism, the park's landscape is one of relatively constant, dynamic change. It represents the most recent activity in the continuing process of the geologic origin and change of the Hawaiian Archipelago, and is also home of the greatest volcanic mass on earth: Mauna Loa, measuring 13,678 feet from the ocean floor.
