Tilt Measurements Still Vital to Volcano Monitoring After More Than a Century
United States Geological Survey

A water tube tiltmeter. The tiltmeter is read by looking into the portal on each pot and adjusting the sight until two pins appear to touch. In fact, one of the pins is a reflection, so having the pins almost touch establishes the exact water level within the pot. The difference in water level gives the tilt, and repeated measurements give changes in tilt over time. Article by Ingrid Johanson. Photo by Michael Poland.

United States Geological Survey

An eruption at the summit of Kilauea volcano began on September 10, 2023. The main fountain, which HVO geologists estimate is approximately 50 meters tall, is on the eastern margin of Halema'uma'u crater. As of approximately 4:30 p.m., the fissures extend approximately 1350 meters to the northeast, onto the downdropped block that formed during the 2018 summit collapse.
