The Mud Volcano Guy - I love and study mud volcanoes! Geomechanics & pore pressure specialist. Opinions my own.
⚒️🧪 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.

🧪⚒️ 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.
I’ll look out for any news!

⚒️🧪 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.

⚒️🧪 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.

⚒️🧪 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!

🧪⚒️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!

I do not recommend ever driving a boat over the eruption like this person did! There is a lot of methane being released, which can ignite.

What a lovely little mud volcano!
No filters, no color enhancement, just the weirdness you'll see here in the park.
This mini volcano is slowly bubbling cold mud which is actually decayed rock and gasses from the acid waste products of microbes living deeper in the venting system of the caldera.

⚒️🧪The Wandan mud volcano in southern Taiwan did not erupt in response to this quake ~70km away, according to its caretaker.
Eruptions of Wandan are often triggered by quakes. Though many eruptions have no quake trigger and sometimes nearby large quakes (like this week’s) don’t trigger any eruption.
