Water level in a deep well on the summit of Kilauea Volcano, Hawaii
Between March 2002 and May 2011 periodic water level measurements were made in the well on the summit of Kilauea Volcano using a 2,000-foot calibrated electric tape (Waterline Envirotech Ltd.) with graduations of 0.01 foot. Water level measurements resumed in March 2018.
Calibration of the electric tape at the USGS Hydrologic Instrumentation Facility (HIF) in November 2018 revealed a displacement of 0.287785 feet over 1,980 feet of the electric tape. We therefore estimate that the accuracy of the water level measurements is 0.3 foot (±9 cm).
Water level measurements were referenced to the top of the wellhead, located at 1103 meters above sea level at the time of drilling in 1973.
