On March 22, USGS Hawaiian Volcano Observatory Scientists measured the water level in Keller Well, located in Kīlauea's south caldera region. Scientists also obtained a water sample. Keller Well is measured and sampled quarterly to monitor how magma supply to Kīlauea's summit reservoirs might impact regional ground water.
