UWD tiltmeter data currently unreliable
The UWD tiltmeter, located near Uēkahuna within Hawaiʻi Volcanoes National Park, experienced a power supply issue starting at 8 a.m. HST on February 5, 2025, and is not currently providing reliable data.
The UWD tiltmeter provides ground deformation information for Kīlauea summit region, and the shallow Halemaʻumaʻu magma reservoir. USGS Hawaiian Volcano Observatory staff are working to resolve this issue and will provide an update when the tiltmeter can be serviced. In the meantime, the SDH and IKI tiltmeters, located southwest of the summit caldera and east of the summit caldera respectively, remain operational.
