Steve Lundblad - Kilauea Tracking Faults & Ground Fault Deformation

4:29 AM · Jan 16, 2023

January 2023 is the Island of Hawaiʻi's 14th annual Volcano Awareness Month. Presentations about Hawaiian volcanoes will be offered around the Island of Hawaiʻi throughout January 2023. Tracking active faults and ground deformation south of Kīlauea caldera with the UH-Hilo Geology Department: The Koa‘e fault system connects Kīlauea’s East and Southwest Rift Zones south of the caldera. Faults here appear as low cliffs, or “scarps” along Hilina Pali Road in Hawai‘i Volcanoes National Park and the area provides an important long-term record of Kīlauea south flank motion. These fault slip during major earthquakes, such as those of May 4, 2018—near the beginning of Kīlauea’s 2018 eruption. Join University of Hawai‘i at Hilo (UHH) geology professor Steve Lundblad as he describes how geology students track ground movements in the Koa‘e fault system, measuring active faults and tracking magmatic intrusions. On-the-ground measurements complement USGS Hawaiian Volcano Observatory geodetic instruments to keep track of this active part of the Kīlauea volcano.
