Excuse the dramatic music on the original video, but incredible webcam footage of PDCs from Semeru progressively infilling a stream channel, looks like it happened to be in just the right place! 🌋

2025 goes down as the ~3rd-warmest year on record (based on ERA5). Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

Nice start to 2026, via stunning but *Baltic* conditions in the Cheviot Hills, Northumberland

It took a lot of effort but finally we are in La Palma!! Exposition about the deployment carried out by our 240 pax @csic.es Canary Islands team (largest Spanish research institution) that got together during the 2021 Tajogaite eruption doing research by sea, land and air. 🌋💪

Following the #HayliGubbi eruption, our paper on the Erta Ale dike of Jun-Jul is finally out. InSAR, optical data and seismicity showed the temporal evolution of the intrusion and the interaction of magmatic sources, including a sill inflation in Hayli Gubbi. @earth-science.bsky.social #geoscience

Our preliminary analysis of the satellite observations of the #hayligubbi #eruption is now available online: comet.nerc.ac.uk/event-respon.... Details of the eruption onset, SO2 emissions and precursory deformation.

Activity at Hayli Gubbi began in July when there was an eruption at Erte Ale. Magma propagated 30 km south passing under Hayli Gubbi. Since then, there has been a small plume, quasi-continuous SO2 emissions and uplift. Details in @uk-comet.bsky.social event response report: tinyurl.com/y3nfdfj8

Thanks Tim. @planet.com imagery from Nov 24 show some subsidence in the southern half of the Erta Ale caldera after the #HayliGubbi eruption (plus widespread ash deposits).

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.

Take-home message from my favourite browser extension: My tab management remains pretty poor; much better than before! (yes the Y axis scale hurts my eyes too)

My latest piece for @geotenerife.bsky.social #VolcanoStories asks one of the key questions locals on La Palma raise with us: “Why haven’t Spain paid the annual €100 million for reconstruction they promised?” Read here: 🇬🇧 geotenerife.com/spanishgovpr... 🇪🇸 geotenerife.com/cuatro-anos-...

We are advertising for a 3-year "Senior Research Associate in Volcanic Petrology and Stratigraphy". Part of a Leverhulme-funded interdisciplinary research grant "Volcanic Histories", focused on research in the Eastern Caribbean. Closing: October 15th www.bristol.ac.uk/jobs/find/de...

🌋 How do scientists monitor volcanoes that we can’t see inside? Volcanoes are powerful and unpredictable, but geophysics gives us a window into the hidden processes deep underground. 📽️Learn more about how we use geophysics to monitor volcanic hazards in this new video! ⬇️ https://loom.ly/d6Hpq7U

This new storymap of the M8.8 Kamchatka Peninsula Earthquake by the USGS is EXCELLENT and will be of great use to anyone teaching classes that involve quakes or tectonics. ⚒️ earthquake.usgs.gov/storymap/ind...

Our July update for reconstruction in #LaPalma following the 2021 eruption for @geotenerife.bsky.social's #VolcanoStories is online and available to read here: geotenerife.com/la-palma-rec... Here's a quick summary of last months update🇮🇨🌋 🧵1/6

This paper by Meredith et al. (2025) examines global city exposure to volcanic hazards, using metrics such as population and distance to GVP Holocene volcanoes to quantify and rank cities at risk. This data has also been visualised through a web app. nhess.copernicus.org/articles/25/...

I am a sucker for tracking down "missing" volcanoes, so I was excited to see some good evidence matching a sulfur spike in the ice core record in ~1831 with a remote caldera in the Kuril Islands. Check out my article exploring these new findings: www.discovermagazine.com/planet-earth...

My favourite part about working from home is the impromptu bird-spotting in the tree outside my window - this morning’s highlights were a Goldcrest and a cheerful gang of Long-Tailed Tits!

Interesting article by the Guardian and Centre for Disaster Protection about pre-financing for disaster aid - the article focuses on climate change, but food for thought for geohazards too ⬇️ www.theguardian.com/before-disas...

We’re in La Palma for GENESIS, an EU Horizon project researching nature-based solutions for underground water resources. An innovative public/private collab for deep demonstrator sites with a strong social package to address local concerns through a Citizen Hub.
