Summit inflation of 15.6 urads recorded on the UWD tiltmeter is now equal to the measured deflation during episode 47. The forecast window for episode 48 fountains is today through Saturday. There have been no precursory overflows.
Kilauea Message 2026-05-27 20:19:04 HST
Slow summit inflation continues tonight, but tilt remains below the level of the forecast window for episode 48 fountains. Tremor and glow remain about the same as previous days.d

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.

North fountain continues to drop and is less than 300 feet (90 meters) high. The UWD tiltmeter recorded about 15 microradians of deflation, about equal to the amount of inflation.
Kilauea Message 2026-05-14 23:00:44 HST
North fountain heights are gradually dropping. One hour ago fountains were about 500 feet (150 meters) high and now they are about 400 feet (120 meters) high. Lava flows have covered about one third of the floor of Halemaʻumaʻu.
