Really cool summary of a recent paper in Geology (gift link 🎁): www.nytimes.com/2026/01/16/s...

Campi Flegrei and Vesuvius in the Bay of Naples area are extremely hazardous. Millions of people live in or near restless volcanoes. Not sure if we're looking at a catastrophic eruption in our lifetime, but a repeat of 1538 Monte Nuovo would still be dramatic.

New study found the largest lahar of the last millennium occurred at Mt Rainier (4.392 m, WA) at the end of the year 1507! 🏔️🌊⌚ Wonderful tree rings... 🥰🌲💍 pubs.geoscienceworld.org/gsa/geology/...

This is a must read. A point that resonates with me: the hubris of administrators to decide what is worthy of a degree. You want to create a school where students can study climate change, yet you plan to fire all the geographers, paleontologists, climatologists, and sedimentologists??

While I was writing an article for the @uk.theconversation.com about why the world's little-known volcanoes may pose the greatest threat, an eruption from a volcano that has had no major documented eruption since the ice age erupted: #HayliGubbi volcano, Ethiopia theconversation.com/the-worlds-l...

Fascinating and timely work on the intrusion that preceded the #HayliGubbi eruption - this will turn out to be a very valuable example for volcanologists!

I whipped up a new post/newsletter extra for the Hayli Gubbi eruption. First time I've had to post an extra edition! #volcano #eruption eruptions.beehiiv.com/p/eruptions-...

An important vote for volcanologists/IAVCEI members that you might have missed (see page 49 in Newsletter), about a "proposal change to allow a president to run for multiple terms of office" Vote here: www.iavceivolcano.org/proposal-cha...

Over the last six weeks, SEES scientists Mengwen, Patrick, Helen & Andrea jointed the Beyond EPICA – Oldest Ice project, which aims to analyse the oldest ice on Earth – up to 1.5 million years old, beyond the 800,000 years previously covered – to understand more about Earth's climate 🧊🧪🥼 @bas.ac.uk

So, no more Smithsonian/USGS Weekly Volcanic Activity Report until the government reopens ...

Great to see @mikeaclare.bsky.social @noc.ac.uk quoted in this piece in the Guardian today www.theguardian.com/news/2025/se... about the Hunga Volcano eruption and the subsequent telecommunications outage in 2022.

I shared this earlier, but this is *exactly* the point I try to make whenever I get the question about "which volcano will be the next to have a big eruption?" It is rarely the ones that are in the headlines at the time.

🌋 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:

We think applying to grad school should be free. App fees create barriers to equity in academia—especially in the US, where students can pay $1,000+ just to be considered. Even waivers don’t fix this. We make the case in our Nature piece: www.nature.com/articles/d41...

SIgn up to our newsletter if you haven't already!

If anyone's going to the @undrr.bsky.social Global Platform for Disaster Risk Reduction in Geneva next week, please reach out. Several of us from the charity @gvra.bsky.social will be there and would be keen to chat about it!

The St Vincent eruption shows that preparedness and early anticipatory action can avert a volcanic disaster!

Now that it's thought the sesimic activity around Santorini is caused by magma, authorities plan an emergency port. Important to note that the vast proportion of magmatic unrest on volcanoes doesn't lead to eruptions, but preparation is key in cases where they might.

It does look like the Washington VAAC (Volcanic Ash Advisory Center) is still up and issuing alerts, but if that stops ... ho boy, that could get messy. The VAAC is a NOAA operation.

Did you know that several @iavcei.bsky.social AWARDS are open for nominations at the moment! Re-vamped instructions can be found here www.iavceivolcano.org/call-for-nom... Each nomination needs 1 lead and 3 supporters. LEAD must be IAVCEI member. Awards support different career stages! 🧵

This effectively ends all nsf-funded disaster research.

Today marks 3 years since the powerful eruption of the Hunga Tonga volcano that generated a tsunami that struck Tonga & severed communication lines. This eruption was a key motivator for the formation of GVRA & our co-founders @mikevolc.bsky.social & @laramani14.bsky.social spoke to DW about it:

Another example why the world needs more geologists and geoscientists. Another route for geology to save the world and a great way to make a job market for those leaving the oil and gas industry 🧪⚒️ www.nature.com/articles/d41...

@laramani14.bsky.social and I in today's @economist.com highlighting the implausible-sounding yet real risk from large volcanic eruptions.

This chart is pretty insane. More of an overnight social/political-type shift than typical tech adoption imo: techcrunch.com/2024/11/19/b...

It's great to see more scientists agree with our mission for global volcano preparedness. This is a really important and insightful read for all:

Here's me and @laramani14.bsky.social on German news @dwnewstoday.bsky.social talking about the neglected state of Global Volcanic Risk:

The Lewotobi volcano activity remains high. Tonight there has been another high-magnitude eruption at 02:41 WITA from the northwest summit vent. Explosions continue, with ash columns up to 15.2 km high. ⚒️ 🌋 www.volcanodiscovery.com/lewotobi/new...

Excited to finally share what @mikevolc.bsky.social & I have been working on for the past few years. We're extremely passionate about this mission & grateful for all the support we've received. But, there's so much to do & it needs all of us - so follow us to see how you can get involved! 🌋

I am glad to serve on the Scientific Advisory Board for the Global Volcano Risk Alliance to help people arounid the world prepare for impactful eruptions. The 2022 Hunga Tonga Hunga Ha'apai eruption was a wake-up call we need to heed. www.globalvolcanoriskalliance.com/home

🌋-ology is a subject dominated by 🌋! Those volcanoes are found in countries 🌍🌎🌏 But knowledge is disproportionately shared from Europe, North America, New Zealand and Japan, where only some of 🌋are found. We need to get better at collaboration and inclusion . 🍀 New papers reflect on this 1/4

New paper: Led by newly-awarded Dr, Anna Brookfield (& her first paper!): 'Magmatic volatile content and the overpressure ‘sweet spot’: implications for volcanic eruption triggering and style': authors.elsevier.com/a/1i2ys1LkU3...

NEW Open Acess paper🚨🌋: Lara Mani & I teamed up with ethicist Anders Sandberg to write 'The ethics of Volcano Geoengineering': shorturl.at/DXYZ5 published in Earth's Future.

Thanks Pete!

Welcome @mikevolc.bsky.social everyone - large scale volcanism is his thing, and now Bluesky is too.
