Volcano Watch — Crack team of geologists measure the Koa‘e fault system

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. These fault-cliffs slip during major earthquakes, such as those of May 4, 2018—near the beginning of Kīlauea’s 2018 eruption.
