Island of Hawaiʻi eruptions 2018–present: Profound landscape and human impacts

This three-day field trip examines deposits and landscape evolution associated with recent eruptions of Kīlauea and Mauna Loa, Hawai‘i, USA, beginning with the lower East Rift Zone eruption and associated partial caldera collapse during the summer of 2018. As of this writing, there have been five eruptions within Kīlauea’s summit caldera, one eruption in the Southwest Rift Zone of Kīlauea, and several intrusions into the south caldera and Southwest Rift Zone since 2018. For the first time since 1984, Mauna Loa erupted in 2022, with lava flows in the caldera and along the Northeast Rift Zone. Recent eruptions contrast significantly with the preceding period, characterized by Kīlauea’s long-lived East Rift Zone eruption at Pu‘u‘ō‘ō from 1983 to 2018 and sustained lava lake activity at the summit from 2008 to 2018.
