🌋 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:

Aeon Magazine @aeon.co · 23d

The science of volcanoes and their relationship with the climate is hard to keep up with. Why do some volcanoes give us little warning before they blow? Are we ignoring the next big eruption?

The next global disaster may be triggered by a catastrophic eruption. How can we prepare for the fire beneath our feet?

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

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.

Volcanic crises! Archives! The ‘real story’ between the lines.

We’re performing a ‘staged reading’ and exploring two crises on #montserrat - with two wonderful playwrights as part of #beinghumanfestival. Come see us in London and also 1/2

Missives - London

A crisis unravelling in letters. Many enquiries have tried to ‘learn lessons’ from crises provoked by natural hazards. Often, disaster is rooted in the misfiring communication and stalled decision-mak...

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.

Famous names—Yellowstone, Etna, Kīlauea—draw the cameras. But the most dangerous volcanoes may be the “quiet” ones, hidden in jungles or beneath the sea, biding their time.

Yet volcanology is chronically underfunded + uneven.
📊 More papers on Mt St Helens alone (1,437) than all 123 volcanoes in Indonesia combined.
Only ~600 of Earth’s 1,302 active volcanoes have any monitoring instruments.

It’s not that rare:

75% of VEI-5 eruptions (like El Chichón or Mt St Helens) followed 100+ yrs of silence.

90% of VEI-6 eruptions (10x bigger) too.
And in regions like Indonesia or the Pacific, a volcano with no known history erupts every 7–10 yrs.

Take El Chichón in Mexico. For centuries it looked like a harmless hill. Then in 1982 it erupted, killing thousands, displacing tens of thousands more… and helping trigger famine in Ethiopia, half a world away.

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...

It should be free to apply to graduate school
