We’ve founded the Global Volcano Risk Alliance (@gvra.bsky.social) to prepare for the eruptions that could reshape our world.

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.
