HVO measures water table at Keller Well
HVO field engineers and staff conducted quarterly work at a deep borehole, known as the Keller Well, at the summit of Kīlauea Volcano today (Sept. 24). They lowered a sensor into the well to measure the distance between the ground surface and the top of the water table, which was 505 m (1657 ft) below the ground surface today. With a water pond at the bottom of Halema‘uma‘u, continued measurements at the Keller Well site provide important data on how the local water table is recharging the summit area following the 2018 collapse events.
