βοΈπ§ͺ Spoke to BBC about Wednesdayβs eruption of the Wandan mud volcano in Taiwan.

The locals ignited it.

The eruption occurred at 3 vents. Sadly one vent was under a house.
This is its 11th eruption in the last ~3 years, most recently in June 2025.

Best with sound on.
Itβs not. I know folks from the geophysical agency that went up the next day to survey it.

Some of the most incredible mud volcano eruptions ever have happened in that part of Timor without ever being reported!
Seismograph recording of low frequency earthquake waves from todayβs earthquake near Timor, ~2800km from my seismograph in Kuala Lumpur.
π§ͺβοΈ Mag 6.3 earthquake just north of Timor today at ~2:04am in Timor Leste (recorded on my home seismometer).
No reported damage or injuries.
Lots of mud volcanoes in that part of Timor that are well within potential reactivation range.
Iβll look out for any news!
It basically is a natural one! Itβs bringing up highly pressured mud, oil and natural gas from deep underground.
11.10.2025 12:51 β π 7 π 0 π¬ 1 π 0Some mud volcanoes, including those in Azerbaijan, are also plumbed into an active hydrocarbon system. So a huge amount of methane is also released during the eruptions. That gas just needs a spark to ignite into a fireball. The ignition occurs naturally and there are several possible mechanisms.

βοΈπ§ͺ Fiery eruption of Otman-Bozdagh mud volcano in Azerbaijan!
The Otman-Bozdagh mud volcano erupted at ~8:27am local time today (11/10/25).
Three eruption phases of between 4-12 minutes were recorded over an ~40 minute period.

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.
βοΈπ§ͺ This weekβs 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.

Nice!! Hope you and the Man are doing well!
I know youβre not on FB anymore, but itβs 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.

βοΈπ§ͺ 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.

Iβm 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.

Map of the Tanimbar Islands with pins marking the locations of ~20 mud volcanoes.
The islands have a many mud volcanoes! Hereβs 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!
Satellite image of a round island with a mud volcano at its center. Two small islands are marked just to the south of the island where mud volcano islands rose up from the sea after the 9th Jan 2023 quake.
Thereβs a long history of earthquake triggered mud volcano eruptions in the Tanimbar and Kai islands. Iβve 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.
βοΈπ§ͺ Todayβs 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.
Iβve 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 youβre right, and I may have found the exact location! Someone has put a position in Google Maps for βVolcancito San Pedroβ, 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.

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.
Small mud volcano vent with visible recently erupted dark grey mud.
Iβm 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 itβs very cute!

A group of people standing around the new baby mud volcano. The mud volcano is about 60cm high and looks to cover an area of ~5m by 5m.
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 Iβm aware of in this part of Peru.

π§ͺβοΈNew 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!
