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.

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.
