The Iceland eruption on the Sundhnúkur crater row has ended, per the Iceland Met Office. So it lasted 3 weeks.

Drone footage of erupting within the cone, then pulls back to show the flow field.

Hard to tell because of the vog, but Kilauea's episode 30 appeared to end just before 1300 local.

Ah, there was an update (excerpt):

"The north vent stopped vigorous fountaining at approximately 12:55 p.m. HST marking the end of the episode. The south vent stopped erupting at approximately 12:50 p.m. HST, Lava fountains reached up to 300 ft (90 m) during this episode.  A new fissure vent that transected the south wall of Halemaʻumaʻu ceased erupting at 4:40 a.m. HST on the morning of August 6. Volcanic gas emissions have greatly decreased. Lava flows from this episode on 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. "

Yeah; nothing much going on.  I wish I'd been in a better position to appreciate when Vidsek started this...

[Buster's Uncle]

v3 has been shaking several times today, sustained, just that I've seen.

Excerpts from Wed's update:

"Models show that episode 31 could start sometime this weekend or early next week."

...

" Images from an overflight on August 6th showed that episode 30 flows had covered nearly 80% the Halemaʻumaʻu crater floor, which now includes the old down dropped block.

The Uēkahuna tiltmeter (UWD) recorded about 22.5 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 about 15 microradians of inflationary tilt since the episode ended."

From the Sunday update:

"Models now show that episode 31 fountains are likely to start between August 18 and August 22 with Tuesday August 19 to Thursday August 21 the most likely window."

Moderate to strong persistent glow was visible at both the north vent and the cracks above it overnight. There was no glow from the south vent or the southern fissure. ...  The onset and strengthening of glow within the north vent may indicate that magma is slowly getting closer to the surface. Images from an overflight on August 6th showed that episode 30 flows had covered nearly 80% the Halemaʻumaʻu crater floor, which now includes the old down dropped block.

The Uēkahuna tiltmeter (UWD) recorded about 22.5 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 just under 19 microradians of inflationary tilt since the episode ended."

...

"NOTE: The V3 camera is currently in Black and White Infrared Mode at night and is much more sensitive to heat and light than the V1 camera at this time."

[Lord Avalon]

Daylight come and there's orange visible in the vent from V1. No splashing at this time.

[Edit] And then I saw a tiny splash.

[Lord Avalon]

Well, that didn't last long. Splashing appeared to end just before 0635 local.

[Edit] Some more splashing starting at 0846.

Hawaii's Kilauea volcano is on the verge of erupting again

[Buster's Uncle]

Fountaining a little bit just since I checked in ten minutes ago...

[Lord Avalon]

I posted in the thread you linked. Where do you want updates to go?

[Buster's Uncle]

Here, I guess.  That was just sharing the article.

From Friday update:

"Three sporadic precursory overflows were observed last night. Over the past 24 hours rapid inflation was recorded across the summit of Kīlauea after 3 days of deflation.  Models now show that episode 31 fountains are likely to start between August 22 and August 24 as long as inflation of the summit continues."

"Precursory vent overflows occurred at 8:46 p.m., 1:03 a.m., and 1:24 a.m. overnight. Spatter bursts, strombolian jetting, and low dome fountains have been intermittently visible in the V1 cam since, 4:15 p.m. yesterday August 21.  These repeated spattering events have built an inner cone within the north vent.

Tilt inflated 2.6 microradians over the past 24 hours at the Uēkahuna tiltmeter (UWD) and there was 2.2 microradians of inflation recorded at the Sandhill tiltmeter (SDH). UWD recorded about 22.5 microradians of deflationary tilt during episode 30, with about 21.2 microradians of inflationary tilt recovered through this morning."

[Lord Avalon]

Looks like lava overflowed the vent just before noon local, then picked up ~1245. Flow is a lot more orange ~1330.

[Lord Avalon]

~1400 enough output to overflow the vent rim nearest V1.
