It DID look like it was petering out when my bedtime rolled around.  It was great while it lasted...

From Monday update:

"Models suggest episode 33 is likely to begin between September 19 and 23, but could start later if the rate of inflation decreases. Moderate glow was visible from the livestream overnight."

"The Uēkahuna tiltmeter (UWD) recorded about 25 microradians of deflationary tilt during this episode. The end of the eruption was coincident with a rapid change from deflation to inflation at the summit and a decrease in seismic tremor intensity. The Uēkahuna tiltmeter (UWD) has recorded approximately 18.8 microradians of inflationary tilt since the episode ended."

Any word on why v1 hasn't been working?

[Lord Avalon]

I think the URL changes, for some reason. So you need to find what's current.

Teeny bit of lava splashing started in the night...

[Lord Avalon]

Some more splashing Wednesday evening. Some low fountaining and overflow began ~2243 local, stopped 0048, resumed 0124, stopped 0142, resumed 0239, stopped again 0252, resumed 0325. Not sure if they'll say the next episode started.

From Thursday update:

"Episode 33 lava fountaining is most likely today or tomorrow at the latest. Precursory vent overflows and gas pistoning suggest the system is building to lava fountaining in the coming 24 hours, but could start later if conditions change."

"The Uēkahuna tiltmeter (UWD) has recorded approximately 22.5 microradians of inflationary tilt since episode 32 ended, and inflation has leveled off this morning. Overnight the magma column has been rising and falling in the vent in cycles (gas pistoning), which has been common in the build up to lava fountaining episodes. Dome fountains up to 10-20 feet (3-6 meters) accompanied filling and overflowing of the vent, drainback was marked by energetic bursts of gas that sent spatter 15-30 feet (5-10 meters) high and landed on the outside of the cone. These gas piston cycles have been occurring every ten minutes, producing small episodic lava flows covering the western crater floor. Vigorous gas pistoning continues this morning."

[Lord Avalon]

Possibly episode 33 began ~0100 local? More vigorous fountaining and more flow of lava down the side of the vent. Still going an hour later. I guess we'll see how sustained this is. The many stops and starts of the previous day differed from the recent usual pattern.

It's really going ATM...

From Friday update:

"Episode 33 of the ongoing Halemaʻumaʻu eruption began at 3:11 a.m. HST on September 19 and is currently fountaining within the summit caldera. Current fountain height is greater than 500 feet (150 meters) and the convective plume is about 10,000 feet AGL (3000 meters AGL). "

"Episode 33 was preceded by sporadic spattering related to gas pistoning starting on September 16 and continuing into September 19th.  Small lava flows began overflowing the vent early on September 17, with overflows becoming larger on the night of September 17-18.  Dome fountains up to 10-20 feet (3-6 meters) accompanied filling and overflowing of the vent, drainback was marked by energetic bursts of gas that sent spatter 15-30 feet (5-10 meters) high and landed on the outside of the cone.  Continuous low lava fountains began at approximately 2:44 a.m. on September 19 and continued to increase in intensity until 3:11 a.m., when tilt showed deflation and seismic tremor increased sharply, marking the start of episode 33. Fountains from the north vent are reaching 500 feet (150 meters) high and feeding multiple lava streams at 3:30 a.m. HST."

[Lord Avalon]

Woo! Above the rim fountaining!

[Buster's Uncle]

THAT is a lot of lava.

[Buster's Uncle]

Just before dawn, there was considerable flow from the uphill vent...
