Mauna Loa: are you ready for the next eruption?

Video Transcript
Mauna Loa is an active volcano, though it has been quiet for almost 30 years. An eruption is not imminent, but patterns of ground deformation on Mauna Loa over the past year may indicate that new, previously unobserved processes may have occurred. Mauna Loa lava flows have the capacity to disrupt lives and commerce throughout the Island of Hawai‘i. What resources are available to help you prepare for the next eruption of Mauna Loa? Join USGS Hawaiian Volcano Observatory geologist Frank Trusdell, who has studied Mauna Loa for two decades, as he presents his talk about Earth’s largest volcano during this Volcano Awareness Month 2022 presentation. Volcano Awareness Month is spearheaded by the USGS–Hawaiian Volcano Observatory, in cooperation with Hawai‘i Volcanoes National Park, Hawaii County Civil Defense Agency, and the University of Hawai‘i at Hilo, and provides informative and engaging public programs about the science and hazards of Hawaiian volcanoes.
