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.
