Hualālai and Mauna Loa Volcanoes, Hawaii USA19.6N 155.8W
The Island of Hawaii is built from five separate shield volcanoes that erupted somewhat sequentially, one overlapping the other. From oldest to youngest these are: Kohala, Mauna Kea, Hualālai, Mauna Loa and Kīlauea.
Two of these can be observed in this orthorectified image: Mauna Loa, the prominent volcano visible towards the center of the island, and Hualālai, near the top by the island’s coast.
Hualālai is a dormant shield volcano on the island of Hawaiʻi in the Hawaiian Islands. Its peak is 8,271 ft (2,521 m) above sea level. It lies roughly due west of the saddle between the much higher volcanoes Mauna Kea and Mauna Loa.
Much of the southern slope (above the town of Kailua-Kona) consists of lava flows covered by a layer of volcanic ash from 10 cm (a few inches) to a meter (3 ft) thick.
Hualālai is built from a well-defined rift zone that trends approximately N50°W across its summit and a less well-defined rift zone that trends northward from a point 3 mi east of the summit. Over 100 cinder and spatter cones are arranged along the rift zones. There is no summit caldera, just a collapse crater (about 0.3 mile across) at the top of a small lava shield.
