July 2, 2024 — Leveling the UWE tiltmeter at the summit of Kīlauea

Detailed Description
Once the sand was removed from the borehole, HVO field engineers could begin the process of leveling the UWE tiltmeter located at the base. As a field engineer manually nudges the tiltmeter in north-south and east-west directions, two voltmeters connected to the tiltmeter electronically provide information on the amount the instrument needed to be tilted in degrees.
