By 11:15 AM, after 6 hours of continuous episode 29 lava fountaining, UWD tiltmeter had recorded 10.8 microradians of deflation. During the past three eruptive episodes, UWD recorded 15.0, 16.3, and 18.5 microradians of deflation.

Episode 29 is certainly different. The "nozzle" like shape of the vent exit has broken down allowing lava to spray in multiple directions and preventing the fountains from growing higher. Deflation has exceeded 7 microradians.

Though the north vent has been the primary host of episode 29 activity, the south vent has been spattering since about 6:05 AM; it last erupted in episode 27 and was completely absent from episode 28.

Episode 29 fountains are currently erupting more sideways than vertically, creating an arcing fountain from the north vent.Flows have covered an estimated 5-10% of the floor of Halema'uma'u crater at this time.

Episode 29 transitioned to high fountains at approximately 5:15 AM. Fountains transitioned from dome fountains less than 100 feet high to more vertical fountains over 200 feet high accompanied by increased tremor and deflation rates.

Precursory spattering began at 3:55 AM followed by lava overflowing the vent at 4:11 AM. Vigorous low fountains and lava flows continue at this time. TEpisode 29 high fountains are expected today, likely within a few hours or less.

Moderate glow has returned to the north vent tonight suggesting the plug may be breaking down. The cracks in the cone just above the vent also continue to glow. Tremor levels remain low but elevated and slow inflation continues.

Fountains from the north vent are now approximately 1000 feet (305 meters) high. Volcanic ash, pumice, and Peleʻs hair are being blown to the south-southwest of the vent.

High fountaining began at 5:15 AM with lava fountains from the north vent growing rapidly from 100 feet (30 meters) to 600-700 feet (200 meters) by 5:30 AM. Based on previous eruptions, lava fountains may exceed 1000 feet during episode 28.

Sustained lava fountains from the north vent are now up to 150 feet (50 meters) high and feed a vigorous flow on the floor of Halemaʻumaʻu, High fountains are expected to begin soon as degassed magma is cleared from the vent.

Episode 28 of the ongoing Halemaʻumaʻu eruption began with low fountains and lava flows from the north vent at 4:10 AM on July 9th. Fountains are currently about 100 feet (30 meters) high but are expected to grow quickly.

At 6:15 p.m. HST on July 7, brief and minor overflows began from the north vent in association with gas piston cycles. These cycles are a common occurrence as summit inflation pushes lava closer to the surface within the vent conduit.
