It's gotten a little impressive - more so while I was off feeding the cats...

Where does all the lava go?

Where does all the lava go?

Just flows down into the crater.

[Buster's Uncle]

There's no outlet?  How is there all that variation in terrain w/ nowhere for all that viscous lava to go?

[Lord Avalon]

There was a collapse back in 2018.

[Lord Avalon]

I don't know how high the fountaining is, but it's going sideways a fair distance. Nice arc seen from V3.

From new update:

"Episode 31 of the ongoing Halemaʻumaʻu eruption began at 2:04 p.m. HST on August 22 and is currently fountaining from the north vent."

"Episode 31 was preceded by continuous spatter in the north vent that began at approximately 8:30 a.m. and continued to increase in intensity until 11:45 a.m., when precursory lava overflows began. Fountaining the north vent began at 2:04 p.m. and and arcuate fountain approximately 100 feet (30 meters) high is feeding multiple lava streams at 2:15 p.m. HST. "

Fountaining ended at 2:51 - there's currently more going on in the uphill vent, but hard to see what isn't just glowing smoke...

From the new update:

"Episode 31 of the ongoing Halemaʻumaʻu eruption ended abruptly at 2:52 a.m. HST on August 23 after 12.6 hours of continuous fountaining.

The north vent stopped erupting at approximately 2:52 a.m. HST marking the end of episode 31. The south and intermediate vents stopped erupting earlier at approximately 12:40 a.m. and 2:46 a.m. HST. Lava fountains from the north vent reached up to 325 ft (100 m) and sustained this height during most of this episode. Fountains from the south and intermediate vents remained small, less than 33 feet (10 meters) for most of the time, but the intermediate vent fountains increased to 60-100 ft (20-30 m) by the evening of August 22.  Approximately 10,900,000 cubic yards (8,400,000 cubic meters) of lava were erupted at an average of 240 cubic yards per second (185 cubic meters per second) during the fountaining phase. Lava flows from this episode covered more than 75% of the floor of Halemaʻumaʻu within the southern part of Kaluapele (Kīlauea caldera) and may continue to exhibit slow movement or incandescence as they cool and solidify over the coming days.

Voluminous fountaining was preceded by continuous spattering in the north vent that began at approximately 8:30 a.m. HST and continued to increase in intensity until 11:45 a.m. HST, when sustained lava overflows began. During this period, a cone was built inside the north vent sealing off part of the old vent.

Fountaining in the north vent began increasing significantly at 2:04 p.m. HST accompanied by deflationary tilt and increasing tremor.  The north vent transitioned to an arcuate fountain approximately 100 feet (30 meters) high feeding multiple lava streams at 2:18 p.m. HST corresponding with the change to steep deflation and high tremor.  Sometime around 4-5 p.m. HST, low spatter fountains began to feed a small flow from the south vent.  At 7:23 p.m. HST, a new intermediate vent opened up in the area of glowing cracks between the north and south vents."

From Monday's update:

"Throughout last night, intermittent spattering was visible at the northern eruptive vent. Summit reinflation is underway at this time, and forecasting models suggest the window for episode 32 is later this week, September 3–6 (Wednesday to Saturday), with September 3–5 (Wednesday to Friday) being the most likely. Episode 32 may occur even later if there are unexpected slowdowns in the summit inflation rate."

"Yesterday evening after sunset, intermittent spattering became visible in webcam views of the Halemaʻumaʻu north vent, and this activity continued overnight. By this morning, the surface of the lava pond within the vent had risen to the point of being barely visible in V1cam's live-stream view. These observations confirm that lava is very near the surface again, following several nights of brightening glow that suggested it was slowly rising from deep.

The Uēkahuna tiltmeter (UWD) recorded about 22 microradians of deflationary tilt during episode 31, and the end of the episode on Saturday, August 23 coincided with a rapid change from deflation to inflation at the summit. Since then, UWD has recorded approximately 18.5 microradians of inflationary tilt in total. "

We have lava flowing...

[Lord Avalon]

"The onset of episode 32 sustained fountaining is likely in the next 24-48 hours if Kīlauea continues to inflate and overflows continue."

Tuesday 0449 local update

[Buster's Uncle]

I'm rootin' for the uphill vent.

[Lord Avalon]

"Episode 32 of the ongoing Halemaʻumaʻu eruption is underway. Vigorous north vent lava fountains started around 6:35 a.m. HST this morning and grew to exceed 330 feet (100 meters) in height, inclined to the northeast and feeding lava flows on the western half of the crater floor. Lava fountaining continues at this time and is likely to continue until the late afternoon or evening today"

From 1017 update

[Lord Avalon]

From Tues 2 Sept 2015 local update:

"Episode 32 of the ongoing Halemaʻumaʻu eruption ended abruptly at 8:01 p.m. HST on September 2 after 13.4 hours of continuous fountaining.

The north vent stopped erupting at approximately 7:49 p.m. HST. The smaller middle and south vents stopped erupting at approximately 8:01 p.m. HST with a few minutes of jetting, marking the end of episode 32. Lava fountains reached up to 500 ft (150 m) during this episode and averaged more than 250 cubic yards per sec (>200 cubic meters per sec) and produced over 12.5 million cubic yards (9.6 million cubic meters) of lava, the highest output for a short-lived fountain episode. "

...

"Lava flows from this episode covered 40-50% of the floor of Halemaʻumaʻu within the southern part of Kaluapele (Kīlauea caldera) may continue to exhibit slow movement or incandescence as they cool and solidify over the coming days. "
