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.

The HVO team also collected a sample of water from the well. Chemical analyses of the water will be conducted to determine and track changes in its composition.

Volcano Watch — A Field Trip to the Mountain of Water

The field day begins with a summit weather check at first light. It is a reflective moment at 6:15 AM atop Kīlauea Volcano, and the fumarole cracks are steaming like the coffee from my thermos. The weather at Halema‘uma‘u crater is cool and dry, with light trade winds from the northeast. We hope for these mornings.
