Measuring Mauna Loa

Volcano Awareness Month: Measuring Mauna Loa

Mauna Loa's 2022 eruption occurred following a 38-year-long period of repose. Although the volcano appeared quiet, monitoring signals were tracking movement beneath the surface in the months leading to the eruption. Join USGS Hawaiian Volcano Observatory geologist Frank Trusdell and geophysicist Ingrid Johanson as they summarize the unrest before the twelve-day-long eruption that began within Mokuʻāweoweo (the summit caldera) and ended on Northeast Rift Zone. Learn how the 2022 eruption compared to previous Mauna Loa eruptions, and what the volcano has been doing in the year since the 2022 eruption ended. Part of Hawai‘i Volcanoes National Park's ongoing After Dark in the Park series of programs and USGS Hawaiian Volcano Observatory's Volcano Awareness Month. Program co-sponsored by Friends of Hawai‘i Volcanoes National Park.
