Great to hear Erik- always liked your writings!

If the Volcanic Eruption Doesn’t Scare You, the Mudflow Should

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... 🥰🌲💍

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??

It's not the first time a hidden volcano has caught us unawares and it won't be the last. This is why we founded the Global Volcano Risk Alliance @gvra.bsky.social, to improve preparedness, strengthen monitoring and make sure the next “unexpected” eruption doesn’t become a global crisis.

The world’s little-known volcanoes pose the greatest threat In regions like the Pacific, South America and Indonesia, an eruption from a volcano with no recorded history occurs every seven to ten years.

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!

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

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.

Many thanks Cin-Ty!

Thanks David, true on both counts!

Thanks for the kind words Ben!

Thanks Vicky!

Thanks Brendan! Indeed - there's still life in those Aussie volcanoes!

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.
