Haleakala Volcano, Maui Island, Hawaii

The unique image of 8000 x 4000 pixels has been manufactured by the fusion of four photographs taken from the Haleakala Volcano Customer Centre, elevation 9740 ft (2969 m) in Maui Island, Hawaii.

Early Hawaiians applied the name Haleakalā (“house of the sun”) to the common mountain. Haleakalā is also the name of a peak on the south western edge of Kaupō Hole. In Hawaiian folklore, the despair at the summit of Haleakalā was dwelling to the grandmother of the demigod Māui. According to the legend, Māui’s grandmother served him capture the sun and drive it to gradual its journey throughout the sky in order to lengthen the working day.

The tallest peak of Haleakalā, at 10,023 feet (3,055 m), is Puʻu ʻUlaʻula (Pink Hill). From the summit one particular seems to be down into a massive despair some 11.25 km (7 mi) throughout, 3.two km (two mi) wide, and just about 800 m (two,600 ft) deep. The surrounding walls are steep and the inside typically barren-hunting with a scattering of volcanic cones.

The most likely active volcano has generated a lot of eruptions in the last thirty,000 decades, together with in the last 500 decades. This volcanic exercise has been together two rift zones, the southwest and east. These two rift zones collectively form an arc that extends from La Perouse Bay on the southwest, via the Haleakalā Crater and to Hāna, to the east. The east rift zone proceeds under the ocean outside of the east coastline of Maui as Haleakalā Ridge, making the mixed rift zones one particular of the longest in the Hawaiian Islands chain.

Until lately, East Maui Volcano was assumed to have last erupted all around 1790, dependent largely on comparisons of maps manufactured for the duration of the voyages of La Perouse and George Vancouver. Latest highly developed dating assessments, on the other hand, have shown that the last eruption was additional most likely to have been in the 17th century. These last flows from the southwest rift zone of Haleakalā make up the significant lava deposits of the Ahihi Kina`u/La Perouse Bay space of South Maui. In addition, opposite to popular perception, Haleakalā “crater” is not volcanic in origin, nor can it properly be termed a caldera (which is shaped via when the summit of a volcano collapses to form a despair). Somewhat, researchers consider that Haleakalā’s “crater” was shaped when the headwalls of two significant erosional valleys merged at the summit of the volcano. These valleys shaped the two significant gaps — Koʻolau on the north side and Kaupō on the south — on either side of the despair.
