Spewing
Kīlauea means spewing or much spreading, which describes the behaviour rather than the shape. It is a shield volcano on the southeastern flank of Mauna Loa, long thought to be a satellite of it and now understood to have its own magma system.
Its summit caldera holds Halemaʻumaʻu, understood as the home of Pele.

The 2018 lower Puna eruption opened fissures through a residential subdivision, destroyed some seven hundred homes, and added new land to the coast. The summit crater collapsed by several hundred metres over the same months. Eruptions have resumed repeatedly since.
Kīlauea is also the name of a town and a lighthouse on the north shore of Kauaʻi, unrelated to the volcano.
