Hawaiian Islands are volcanic

The Formation of the Hawaiian Islands The Formation of the Hawaiian Islands [ HCV Home ][Formation of the Islands][ Active Hawaiian Volcanoes ][ General Info ]    The Hawaiian Islands are volcanic in origin. Each island ismade up of at least one primary volcano, although many islandsare composites of more than one. The Big Island, for instance,is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea,Hualalai and Kohala. Mauna Loa is the largest active volcano onEarth. Kilauea is presently one of the most productive volcanoeson Earth (in terms of how much lava it erupts each year). The primary volcanoes on eachof the islands are known as a shield volcanoes, which are gently sloping mountains produced from a large number of generally very fluid lava flows.    Hawaiian volcanoes primarily erupt a type of rock known as basalt. When molten, basalt produces liquids of relatively high fluidity, compared to volcanoesthat erupt more silica rich magma types such as andesite, dacite or rhyolite. The fluidity of molten basalt favors the formation of lava flows,which is why the Hawaiian volcanoes generally have gentle sloping sides. Bycontrast, lavas with higher silica content are more viscous and commonly produce either thicker, shorter lava flows, thick blocky deposits and/orthick beds of ash that fall from the sky following explosive eruptions.These other types of volcanoes (common outside of Hawaii) are typically steepersided.    The Hawaiian volcanoes were produced by the Hawaiian hot spot, which is presently under the Big Island of Hawaii.The image below shows the islands of the Hawaiian chainand the intervening shallows, banks and reefs along a line from southeastto northwest. Note that the islands of Lanai and Kahoolawe are not shownbecause they would "overlap" with Molokai and Maui, respectively( see the map of the Islands on the Hawaiian Volcanoes page )In general, when you move along the island chain from southeast (Hawaii) to northwest, (Kure), the volcanoes become older and older.     The aging of the islands with distance from the current hot spotis demonstrated in the diagram below, where distance along thechain is approximated as distance away from Kilauea volcano (theyoungest above-sea-level Hawaiian volcano). In fact, even beyond Kurethe Hawaiian chain continues as a series of now-submergedformer islands known collectively as the Emperorseamounts. The two primary volcanoes that make up Oahu (where Honolulu is) have not erupted for well over a million years!    The age trend of the volcanoes is thought to be due tothe way in which the islands are built on the moving sea floor of the NorthPacific Ocean: the Pacific Ocean is mostly floored by a single tectonic plate(known as the "Pacific Plate")that is moving over the layer in the Earth known as the Asthenosphere.This movement takes it to the northwest compared to the layers below itat a rate of 5 to 10 cm/yr (the rate depends on where you are on it). As theplate moves over a fixed spot deeper in the Earth where magma (moltenlava) forms, a new volcano can punch through this plate and createan island. The Hawaiian Islands are believed to be formed from onesuch 'hot spot'. As the plate moves away, the volcano stops eruptingand a new one is formed in its place. With time, the volcanoes keepdrifting westward and getting older relative to the one active volcanothat is over the hot spot. As they age, the crust upon which they sitcools and subsides. This, combined with erosion of the islands onceactive volcanism stops, leads to a shrinking of the islands with ageand their eventual submergence below the ocean surface.    Importantly, the time over which various active volcanoes on the islandsremain active is long (hunders of thousands of years) so that significantoverlap in ages occur on neighboring islands. For instance although Haleakala volcano on Mauiis a great distance away from the presently erupting Kilauea, Haleakalalast erupted only about 200 years ago. Currently there are 3 Hawai'ian volcanoes that we can easily classify as active: Kilauea, actively erupting since 1983 Mauna Loa, which last erupted in 1984 and is building for a new eruption inthe next few years Loihi, which erupted in 1996   All three of these active Hawaiian volcanoes sharethe Hawaiian hot spot, but retain unique volcanic histories and compositions.You can view a schematic representationof the geometry of this situation HERE The most likely Dormant volcanoes are: Hualalai, which last erupted in 1801 Haleakala, which last erupted in about 1790 Mauna Kea, which last erupted about 4,000 years ago.    Here is some additional general age information from USGS Professional Paper 1350 , Chapter 1 by Clague and Dalrymple, pages 5-54 (1987). Data from that source has been augmented by data and information in Garcia et al. Lithos , vol 20, pages 323-336 (1987) and Clague (1996) in The Origin and Evolution of Pacific Island biotas, New Guniea to Eastern Polynesia, patterns and processes (Keast and Miller, editors), pages 35-50.
