⚒️🧪 This week’s massive M8.8 earthquake off Kamchatka was caused by an ~160x 480km fault surface sliding by about 9m. In contrast, these lovely itsy-bitsy faults have slips of only about 1cm or so, but are no less impressive.

Sedimentary rock made up of dozens of thin layers (a few mm each). The layers are all cut and offset by ~1cm by many small cracks.

Nice!! Hope you and the Man are doing well!

I know you’re not on FB anymore, but it’s been nice seeing all the figures from this paper getting heavily promoted and liked by this FB group. Brings back memories of the field trip I tagged along on.

⚒️🧪 Geophysical Institute of Peru article with preliminary findings about the new baby mud volcano reported last week.

Updates include that the mud volcano was actually noticed in Nov 2024 and the gryphon has built up over the last ~3 months.

The mud is room temperature.

I’m not an expert on Californian seismicity. However, I have not heard of any unusual activity from experts, and I know there are often folks making up false alarming claims.

Mark Tingay @marktingay.bsky.social · Jul 14

The islands have a many mud volcanoes! Here’s my incomplete map. Many MVs are remote, and eruptions may not be reported.

Whilst the quake could potentially trigger an eruption, I note that triggered eruptions in the area have historically required larger quakes, greater than M7.0.

We will see!

There’s a long history of earthquake triggered mud volcano eruptions in the Tanimbar and Kai islands. I’ve found mentions in papers of triggered eruptions going back >200 years!

Most recently, the M7.9 9th Jan 2024 quake caused two tiny islands to rise up next to the big Pulau Kabawa mud volcano.

⚒️🧪 Today’s big earthquake near the Tanimbar Islands was close and large enough to potentially trigger eruptions in the many mud volcanoes in those islands, as has previously happened numerous times in the region.

I’ve not seen any reports of mud volcanic activity, but will keep an eye out for news!

@brandontbishop.bsky.social interesting. Maybe you are right that it may have some magmatic link.

There are two hot mineral springs near by (one active) that have built up small cones, one ~15km away and one ~38km away.

Yes, I think you’re right, and I may have found the exact location! Someone has put a position in Google Maps for ‘Volcancito San Pedro’, which has photos of the mud volcano and matches with details in a local news story.

Oh yeah. The flows from mud volcanoes can be amazing with their shapes, colours, pattens and textures.

Mark Tingay @marktingay.bsky.social · Jul 12

I don’t think it is hot at all. I would suspect the mud is 10-30°C

The geophysicist interviewed was indicating that it’s not near any active volcanism. The vent itself also doesn’t suggest that it may be hydrothermally driven. It doesn’t really look like how MVs usually look when near and influenced by volcanism.

Mark Tingay @marktingay.bsky.social · Jul 12

SW? I realised id gotten that wrong, but the map in the article has it NE of Cuzco!

I am hunting around to see if I can find more info, but a bit busy with other stuff at the moment. Plus, the best and most reliable info is likely in Spanish.

I will also try to contact the geophysicist mentioned.

I’m not very familiar with the geology there, but, from the little I know, it seems an unusual place to find one.

This mud volcano is not related in any way to the magmatic volcanoes of the Andes.

What I do know is that it’s very cute!

Peru is not at all well known for mud volcanoes!! Two active mud volcanoes have been documented in Southern Peru, but this new one is the first mud volcano I’m aware of in this part of Peru.

🧪⚒️New baby mud volcano found in Peru!

Locals first noticed this small mud volcano just to the NW of Cuzco on the 6th of July.

It consists of a single ~60cm high gryphon that is gently erupting and bubbling away.

Awww! Welcome to the world you cute little thing!

Go home Google AI, you’re drunk!

There’s no way the fancy aristocracy characters in Cluedo would ever go to jail!

Google AI answer to the question “what happens if a player rolls doubles in Cluedo?”. The AI answers that players who roll doubles three times in a row go to jail. Despite Cluedo being about solving a murder, there is no Jail in Cluedo. The AI is confusing Cluedo with Monopoly.

I sure do have videos of this mud volcano burning at night in previous eruptions!

Another video from 張寶惠.

The eruptions are lit by the locals to flare off the methane gas bursting out with the mud.

⚒️🧪 The Wandan mud volcano in southern Taiwan erupted again today.

The eruption lasted from ~5am to ~3:40pm. This is its 10th eruption in the last 3 years, most recently the 6th July 2024.

Video courtesy of my friend 張寶惠, the mud volcano temple caretaker.

Best with sound on!

Yep. It’s telling that I posted this on a few other socials and it’s not had much engagement. BlueSky does tend to be much better, especially on science feeds that are relatively trustworthy.
