A magnitude 5.6 earthquake just struck directly beneath Mount Fuji — JMA puts the follow-up probability at 10-20% and the monitoring window at 7 days. The 1707 precedent took 49.

JMA confirmed no changes in volcanic monitoring data after the June 26th M5.6 at 20km depth near Fujikawaguchiko. The agency issued a standard one-week caution window citing 10-20% historical frequency of comparable follow-up events.

The part missing from most coverage: the 2012 NIED study estimated magma chamber pressure beneath Fuji at 1.6 MPa following the Tōhoku earthquake — 16x the 0.1 MPa threshold associated with the 1707 Hōei eruption, which occurred 49 days after the M8.6 Nankai earthquake, well outside the standard monitoring window.

The Exact moment Kilauea stops erupting after a 10 hour eruption (Sorry for the music, read description).

Sorry for the music, This was originally one of way too many clips that I used in an overall eruption video I put up on youtube back in January. Months later, I ran out of room on my PC for new videos and so I deleted a bunch of old clips, including this original clip. So this is the only version I have now, with the music at the end of my edited video where it fades to black. It was still absolutely amazing to see in person though!

Odd question alert ❗️❗️🚨

Like the title said, this is a very odd and specific question. But I’ve no where else to turn besides Reddit. Hopefully my autism isn’t showing that badly 😭

I’m world-building with my warrior cats fanclans, but know next to nothing about geology or volcanoes in general. And all the characters are cats, so you cant exactly search google for this information.

One of my plot points features a clan getting wiped out by ash from a neighboring volcano Pompeii style. 

In theory,

How big would this volcano have to be, and how far away? The volcano should be close enough to warm sunclan’s territory in the winter months, but far enough not to destroy the other clans.

From what I’ve heard, Housecats can travel 3-5 miles a day, so let’s say that is roughly the distance between Sunclan and the other clans.

Would it be possible for the winds to direct the ash and soot onto mainly Sunclan.

How would their demise play out realistically? Again, I only briefly looked into the Pompeii volcano, so I know next to nothing about volcanos.

Finally, Is this even possible? If not what can I change to make it possible?

Poorly made map:

Highly recommend visiting Yellowstone at dawn or in the middle of the night. [OC]

Which volcano is this? It is in Peru, photo from a LAN Peru Cusco-Juliaca flight, in June 2002.

Title says it all. Very eager to know this community's opinions on what I assume is most definitely a volcano. Because of the route and maybe also the crater shape, I wonder if it is Sabancaya. But when I look at a 2002 Google Earth view of Sabancaya, it shows it as active, obscured by smoke/ gas.

I took the picture while visiting Peru. This was just a regular commercial flight, on an Airbus A320-series aircraft, based on the winglet.

Thanks for your opinions!

Mount Etna eruption back in February 2021, seen from Giarre (Sicily)

Found this shot in my gallery and wanted to share. This was taken during one of the spectacular paroxysms of February 2021. The picture captures the massive lava fountain and ash cloud glowing at dusk, contrasting with the snow still on the mountain. Living at the slopes of the volcano means having this kind of unreal backyard view.

What happens to the world if Yellowstone was to erupt?

Sitting here reading about how the Pacific Ring of Fire is having quite a month. I watched a documentary about Yellowstone years ago that said an eruption was “overdue”. Wondering if anyone has thoughts on things that would change in the short and long term if that happened.

Introducing The Volcano - my original painting inspired from the eruption from the Pu‘u ‘Ō‘ō vent of Kilauea volcano, Hawaii that began on January 3rd, 1983

I am a volcano, mountain and a hiking enthusiast and decided to place my love for that on the canvas!
My painting is inspired from the eruption from the Pu‘u ‘Ō‘ō vent of Kilauea volcano, Hawaii that began on January 3rd, 1983.
Would appreciate your feedback on the execution of the eruption and the lava.
