Because Mauna Loa and Kīlauea are active volcanoes, the island is growing. Between January 1983 and September 2002, lava flows added to the island. Lava flowing from Kīlauea destroyed several towns, including Kapoho in 1960 and again in 2018, and Kalapana and Kaimū in 1990. In 1987 lava filled in "Queen's Bath", a large, L-shaped, freshwater pool in the Kalapana area. Another 875 acres were added between May and July 2018 by the 2018 lower Puna eruption, with "Fissure 8" located within Leilani Estates subdivision being a primary source of the lava. A lake known as "Green Lake" was covered by lava in that eruption as well as Ahalanui Beach Park and part of Isaac Hale Beach Park, the latter of which was inundated with black sand, rendering its boatramp unusable. Mauna Loa erupted briefly in 2022, 38 years after the prior activity.
