Volcanos

[Vidsek]

Seemed time to dedicate a thread to all things magma, lava, tephra, and hydrothermal.  Oh, ok, we'll toss in intrusions and batholiths as well.

Currently, the Kilauea volcano on the Big Island of Hawai'i is starting it's 27th episode of this eruption.
And I mean starting right now: early pre-fountaining started this morning about 07:00 island time (four and a half hours ago) and has been growing into very low fountaining.  It will keep building fairly fast and in a couple hours should be spectacular.

Best views will be the V 1 and V 3 streaming cameras.

Hey actually, if you intend this as a discussion thread, that's why I moved it into Rec Commons where it'll get more discussion.  Volcanos are cool, so keep it coming.

Early evening there, and the orange glow in lava on the ground is visible. I think output increased compared to earlier in the day. One of the cams showed the top height of the lava spurt, where the other one's view cut it off. But recently I saw the lava occasionally exceed the view of both cams. And V2

offers a nice view of the breadth of the flow.

I pulled up the video late last night, and found no orange rivers, no orange fountains of lava, only some residual glowing spots. Ran back the video and found the high fountains of lava stopped just before 20:00 HST. Per report https://volcanoes.usgs.gov/hans-public/notice/DOI-USGS-HVO-2025-06-30T00:11:56+00:00

"Episode 29 of the ongoing Halemaʻumaʻu eruption ended abruptly at 7:54 p.m. HST on June 29 after nearly 11 hours of continuous fountaining.

Waning north vent fountains stopped completely at 7:54 p.m. HST, several hours after reaching maximum heights up to 1,100 ft (340 m). Flames were visible at the south vent for a few minutes afterwards. High fountains produced approximately 1.6 billion gallons (6.2 million cubic meters) of lava covering 80% of the crater floor."

Oh heck, that's way more active then 10 years ago.

Interesting contrast: during the day you can see a plume of smoke coming from the vent. At night you only see a little bit, but it's glowing orange from the lava (magma?) below.

[Lord Avalon]

Probable lava fountaining July 7-11, most likely 8-10.

July 5 update excerpt: "Summit inflation continues at this time, along with persistent, low-level seismic tremor. Incandescent glow has been visible at the north vent in overnight webcam views, as well as intermittent minor lava spattering and jetting. These observations indicate that another lava fountaining episode is probable, and the current summit inflation rate suggests it will occur sometime between July 7 and 11, with July 8–10 being the most likely."

Some lava has flowed out of the vent and cooled, accompanied by occasional splashing. It's about 1830 local on 7/7. Best view is V3, lower right.

  Every time I click on that YouTube link, its nighttime over there.

So I'm on time for watching this pot boil over?  Lucky me.

[Lord Avalon]

Every time I click on that YouTube link, its nighttime over there.

Well, they are UTC -10.

[bvanevery]

If it really blows, will night turn into day?  Sorta?

[Lord Avalon]

The nighttime view has the benefit of the smoke lit by the orange glow of the magma. Currently V1 has a nice view, 0237 local.

[Lord Avalon]

Tuned in this morning (July 8, 2318 local), to see a new flow of lava that had started earlier, running out of camera view. Only a bit of low-level jetting, more roiling of lava in the vent. After ~5 min it had stopped. Eventually the lava cooled.

Recently (0423 local) activity has picked up. Not sure when the low-level fountaining started, but there is more new flow running down from the vent, and movement can be seen of lava running downhill. V2 currently showing more of the extent of the flow.

[Edit] 0427, V3 cam view shifted to the right so see more of the flow.
