![]() ![]() ![]() Māhukona off the northwest corner of the island has already disappeared below the surface of the ocean. ![]() Some geologists count seven volcanoes as building the island, which include the submarine volcanoes Māhukona and Kamaʻehuakanaloa (formerly Lōʻihi) as parts of the base of the island. Mauna Loa erupted in 2022 after 38 years. ![]() Another 875 acres were added between May to July, 2018 by the 2018 lower Puna eruption. In 1987 lava filled in "Queen's Bath", a large, L-shaped, freshwater pool in the Kalapana area. Lava flowing from Kīlauea has destroyed several towns, including Kapoho in 1960 and again in 2018, and Kalapana and Kaimū in 1990. Between January 1983 and September 2002, lava flows added 543 acres (220 ha) to the island. Geologists now consider these "outcrops" to be part of the earlier building of Mauna Loa.īecause Mauna Loa and Kīlauea are active volcanoes, the island of Hawaii is still growing. Geological evidence from exposures of old surfaces on the south and west flanks of Mauna Loa led to the proposal that two ancient volcanic shields (named Ninole and Kulani) were all but buried by the younger Mauna Loa.
