Summit inflation resumed just after noon today and is continuing at a slow pace. The summit tiltmeter UWD recorded about 2 microradians of deflation, which may push back the onset of episode 48 fountaining depending on overnight inflation.

A sharp deflation of Kīlauea's summit began just after 4 pm HST and has recorded a drop of 1 microradian on the UWD tiltmeter. This will push back the episode 48 fountain forecast to May 26-27. No precursory activity has been observed.
