The north vent fountain has increased to about 50-80 feet (15-20 meters) and continues to feed a substantial flow extending over a half a mile (1 kilometer) onto the floor of Halemaʻumaʻu crater. The onset of episode 53 appears close.

The small overflow that began at about 1 pm HST gradually increased in size until, abruptly, at 1:45 pm HST the volume increased greatly. Inflation stopped at the same time and a double dome fountain feeding a broad overflow formed.

Precursory overflows have begun from the north vent. The first was at 11:20 am HST and lasted 2 minutes. The second began at 11:35 and lasted roughly 4 minutes. Summit inflation is continuing.

Rapid inflation resumed at 9:40 a.m. this morning after 3.5 hours of slow inflation. The UWD tiltmeter has recovered 14.1 of the 14.4 microradians lost during episode 52. Episode 53 is likely to start later today or tomorrow.

Currently, moderate glow is observed from both the north vent and the collapse above the south vent (formerly called the crack). The south vent is dark. The new collapse began glowing around 8:45 pm and increased just before 10 pm HST.

Rapid re-inflation of the summit continues with UWD recording over 2 microradians in about 12 hours. Projections indicate if this rate is sustained, episode 53 could begin as early as tomorrow afternoon and no later than Thursday.

The Uēkahuna (UWD) tiltmeter began recording inflation at 10:30 a.m. today. It has recovered over 1 microradian of tilt since then. The current rate is about 3 urad per day.
