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.

Volcano Watch — Join the Statewide Earthquake Preparedness Drill on 10/15 at 10:15

Major earthquakes cannot be predicted. Successful earthquake predictions need to have three things correct: the location, the time, and the magnitude. The best anyone can reliably do is get two out of three correct. And the most important thing for everyone to do is prepare—have a plan, build a kit, and practice drills. Join us for the ShakeOut on October 15th!

Volcano Watch — That didn’t feel like a Magnitude-4? What do earthquake measurements mean?

Residents on the Island of Hawaiʻi are accustomed to feeling earthquakes. As the ground shaking subsides and the safety of everyone around is assured, one of the first questions we typically ask is “how big was that earthquake?”

New article — From Lava to Water: A New Era at Kīlauea

Last year at Kīlauea Volcano, water appeared within the summit caldera where a lava lake had been for the previous decade. This piece covers the reliance on Unoccupied Aircraft Systems (UAS) for sampling the lake water, the growth and significance of the new water lake, and implications for future eruptive activity at Kīlauea's summit.
