It is!
No idea! Could be gas, fire or mud really.
For official information please see online updates in the thread from the Colombian Geological Service.
Thatβs all for now. Iβll post more info as it comes in.
No one was hurt, but reports indicate some livestock was killed and large cracks formed in the adjacent San Juan de UrabΓ‘ and San Juancito road.
I had this marked on my personal map of Colombian mud volcanoes already (red circle), but have no information on it - not even a name!
For now I will call it the San Juan de UrabΓ‘ mud volcano, but people on Google Maps have today labelled it as the San Juancito mud volcano.
The mud volcano is located ~2km south of the town of San Juan de UrabΓ‘ (8.7288, -76.5141). Pre-eruption satellite images show that itβs a fairly small and usually low activity mud volcano.
π§ͺβοΈ A big eruption occurred at a mud volcano in Colombia on the night of the 25th February 2026.

Yes. Or just violently erupted rocks banging together and creating a spark.
No. Not molten at all. Just mud and gas.
A friend from the Geological Institute of Azerbaijan, Dr Orhan Abbasov, climbed up DaΕmΙrdan to survey the eruption. You can see the thick dark fresh mud flows and that the main vent was still alight from methane seeping out.
βοΈπ§ͺFiery Mud Volcano Eruption!
The DaΕmΙrdan (Dashmardan) mud volcano in Azerbaijan erupted ~16:50 on the 30th Jan 2026. The eruption lasted ~15 mins and was accompanied by a pillar of flame several hundred meters high. DaΕmΙrdan had previous documented eruptions in 1866, 1954, 1976, 1986 and 2011.
βοΈπ§ͺ Spoke to BBC about Wednesdayβs eruption of the Wandan mud volcano in Taiwan.

The locals ignited it.
βοΈπ§ͺ The Wandan mud volcano in southern Taiwan erupted again yesterday (12/11/25)!
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.
Sadly not me!!
If any bright folks out there can access pre- and post- quake satellite images, Iβd love to please collaborate and look for any mud volcano triggering!
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.
Some 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.
More information on Otman-Bozdagh, and its last fiery eruptions in 2017 and 2018, can be found in my old thread here.

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.
