A quick summary of 2025 New Zealand earthquakes. GeoNet located more than 21 000 earthquakes in New Zealand and the Kermadec region. Magnitudes range from -0.3 – 6.8 and depth from 0 (just below the surface) – 750 km. 1/ 🧪

Just after midnight on 1 January 2026, a new eruption started from #Etna's eastern flank: a fissure opened at ~2100 m elevation, and a lava flow is descending through the desert-like Valle del Bove. Photos taken in the evening of 1 January from Etna's east and southeast flanks

Stop what you're doing and watch this - absolutely wild!! Kilauea, Hawaii #Volcano www.youtube.com/watch?v=fiyt...

Still smiling after another amazing visit to Yasur volcano in Vanuatu just over a week ago. We were there to help VMGD install new infrasound microphones in their monitoring network, a vital tool for tracking eruptive activity.

Here is a hastily constructed animated gif from different NASA satellites showing the progression of the Hayli Gubbi eruption. Note the tall ash plume spreading NE (right) and a lower, light tan ash flow(?) moving NNW. #eruption #volcano

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.

Solid advice here but I disagree with the first point for one reason: accessibility. Having text as 2 or 3 short bullet points on your slide will help deaf and HoH folks (such as myself) follow your talk as they might not be able to hear you.

Kīlauea episode 35 has arrived. The double fountain shot is from one of the HVO interns, Christina. All are taken from the public viewing areas.

Using earthquake data we image seismic velocity 'anomalies' at 7-12 km depth beneath geothermal systems, north of Taupō, New Zealand. We interpret the anomalies as representing crystal-rich partial melt – the deep heat sources driving the geothermal systems. doi.org/10.1016/j.jv... #seismology

Once upon a time, the platform formerly known as Twitter was a vibrant meeting-place where scientists, the public, official orgs and more besides could exchange knowledge. I set out to find out how effective it could be for disseminating geoscience info Skip to the paper ☛ doi.org/10.1038/s432...

Very happy to see El Mestel's work on seismicity at Taupō volcano published today in JGR: agupubs.onlinelibrary.wiley.com/doi/10.1029/... El used a new seismic network to look at Taupō in more detail than anyone has done before

Great to see this new work by Sam Mitchinson published this week! He quantified the uncertainty in expert classification of volcano seismic events, with important implications for ML model accuracy. 🌋

🌋 Excited to share my new essay in Aeon: one of the most underappreciated global risks isn’t an asteroid or supervolcano—it’s the eruptions we don’t see coming:

Snap, crackle and pop! Love the booming explosions from the summit vent in the background.

The Southeast Crater - youngest and most active of the four summit craters of #Etna - producing Strombolian explosions and a lava flow on the evening of 24 August 2025. The current summit eruption started on 14 August. Photo taken from Nicolosi on Etna's south flank.

Geological Survey of Japan captured the moment that a small PDC went down at Shinmoedake in Kirishima Volcanic Complex. www.gsj.jp/hazards/volc...

Ruapehu was fully out on the flight back to Palmy yesterday.

Good morning #IAVCEI2025! I have two presentations for you today. I have a talk about the amazing acoustics of the Hunga eruption at 3.45, followed by a poster on the 2022 unrest episode at Taupō (which inc. a tsunami!) See you there!

The morning sunrise over the lake almost makes up for the lack of volcanoes in Geneva #IAVCEI2025

On the last leg of my journey to Geneva for #IAVCEI2025. Looking forward to meeting friends and learning new science!

Indonesia’s Mount Lewotobi Laki-Laki erupted, sending ash and smoke into the sky. Authorities evacuated nearby villages as a precaution. Scientists are monitoring gas and seismic activity closely. #Volcano #Indonesia #DisasterPreparedness ⚒️🌋🧪 AP: apnews.com/article/indo...

Lots of ash from the fire fountain in this Hawaii live feed from USGS. www.youtube.com/live/oG5zz9S...

Episode 23 of the ongoing eruption at Kīlauea recently ended. Here's a video from the USGS showing a time-lapse of the fountaining. 🧪⚒️🌋 HVO www.usgs.gov/observatorie... USGS Volcano Hazards Program www.usgs.gov/vhp

#volcan #volcano #Kilauea 🇺🇸 C'est partit pour une nouvelle séquences de fontaine de lave!/Let's go for a new lava fountain sequence!

New Ruapehu VAB: Te Wai ā-moe temperatures are cooling slightly but low-level activity continues. 🇳🇿🌋 Volcanic Alert Level remains at 1. : www.geonet.org.nz/mbl/news/3rC...

"Drums, drums in the deep" Maybe the Mines of Moria exist beneath Ruapehu volcano? Check out our new paper led by Liam Bramwell detailing the incredible "drumbeat" earthquakes and tremor seen in 2022! 🇳🇿🌋⚒️

The situation in #Sakurajima volcano is gradually becoming at the concerning level. Today Prof. Emeritus Masato Iguchi told to TV that the level of the edifice inflation right now is one of the largest since the beginning of the observation in 1985. newsdig.tbs.co.jp/articles/-/1...

More stunning acquisitions by #sentinel3 of #Iceland from today. The last couple of days have been exceptionally warm with many stations showing more than 20°C.

We are still observing some minor ash emissions at Whakaari/White Island. In the past few days, wind directions have meant the plume has travelled towards the mainland but we don't expect any ashfall. VAL remains at Level 3 and ACC at Orange

Feels like Etna and Kilauea are in a competition for who can do the most fire fountains in 2025.

Fantastic to see this work published. If you want to get your hands on 17 years of earthquake data from the TVZ, then check out the paper and head over to Zenodo: zenodo.org/records/1509...

**BIG NEWS in the geology world!** For the first time, scientists spotted an active eruption along the mid-ocean ridge!! They visited the hydrothermal vent the day before, where a vibrant ecosystem thrived in the sweltering water. The next day, everything was gone. ⚒️🧪 My latest for @nytimes.com

Given the announcement today of a recently observed submarine eruption, it's a good time to reflect on what other submarine volcanic behaviors have been observed. Follow along for some undersea volcanic fun. 🌋🌊🧪

Hello Bluesky! We are the 'Volcanology at Liverpool' research group at the School of Environmental Sciences, University of Liverpool in the UK and are excited to join this fantastic community! 🤩🌋

Another major eruption of the Poas Volcano this morning. Authorities have declared Red-Orange Warning in surrounding counties, neighbor areas are further affected by ash distribution 🪨🧪🌋 Seismic updates and direct feeds by OVSICORI: www.facebook.com/share/v/1X8z...

Our recent observations at Whakaari have suggested a general increase in activity, therefore we've raised the VAL to Level 3 🇳🇿🌋

A few scenes (with unusually clear sound due to absence of wind) of the Strombolian activity at #Etna's Southeast Crater during the night of 2-3 April 2025. Note the cute little secondary vent in the latter part of the video.

Some relaxing lava fountaining for your viewing pleasure at Kilauea right now: www.youtube.com/live/fiyttmA... ⚒️🌋

Hlly moly, these fountains are huge.

Flights leaving Bali cancelled after volcanic eruption shoots ash plume 8km into sky

A few scenes of the new Strombolian activity at #Etna 's Southeast Crater during the night of 15-16 March 2025, seen from 5 km distance. Looks big, but actually this is a rather modest activity for Etna standards.
