Several summit eruptions since December 2020 created lava lakes within Halema‘uma‘u crater, which have been slowly filling the collapsed area that formed in 2018. In 2018, the decades-long continuous activity on the East Rift Zone ended, and the summit lava lake drained following an intrusion into, and eruption from, Kīlauea's lower East Rift Zone. At the summit, a vent within Halema‘uma‘u hosted an active lava pond and vigorous gas plume from 2008 to 2018. From 1983 to 2018 eruptive activity was nearly continuous along the volcano's East Rift Zone. Since 1952, Kīlauea has erupted dozens of times. The advance of the frontier line that characterized shifts in population distribution for the previous 100 years was complete. 1790 to 2010 In 1890, the Superintendent of the Census described an unbroken line of settlement stretching across the country. Kīlauea ranks among the world's most active volcanoes and may even top the list.

However, research over the past few decades shows clearly that Kīlauea has its own magma-plumbing system, extending to the surface from more than 60 km deep in the earth. population density based on the 18 Censuses. It is a subset of larger map historic map that also displays the U.S. Topographically Kīlauea appears as only a bulge on the southeastern flank of Mauna Loa, and so for many years Kīlauea was thought to be a mere satellite of its giant neighbor, not a separate volcano. This map displays the population density of the United States according to the 17 Censuses.
