Global supervolcano threat rises as scientists sound the alarm
Story by Joseph Shavit • 1h


Volcanoes have stirred human awe for thousands of years, with their bursts of fire and rivers of molten rock. Yet, beyond the familiar cone-shaped peaks lies a more silent, hidden danger—supervolcanoes. These colossal forces don’t rumble often, but when they do, the aftermath can reach across continents. Studying these sleeping giants offers not just fascinating science but also sobering warnings for the planet’s future.
 
Supervolcanoes are in a class of their own. Unlike typical eruptions, these blasts eject more than 1,000 cubic kilometers of material. That’s enough to bury entire cities under layers of ash. They don’t look like the volcanoes you might picture either. Instead of peaks, they often form as massive calderas—huge sunken areas created when the magma chamber empties and collapses.

Their eruptions sit at the top of the Volcanic Explosivity Index, labeled VEI-8. That’s the highest score possible. To compare, the famous eruption that buried Pompeii was a VEI-5—far less powerful. A single VEI-8 event would not just devastate the surrounding region. It could alter weather patterns, block sunlight, and disrupt global agriculture.

Supervolcanoes act on long, quiet timelines, making them hard to predict. Their sheer potential, however, keeps scientists watchful. These rare eruptions could shift climate, rewrite coastlines, and shake global systems. Understanding their patterns is key to preparing for the unimaginable.

The unity of government which constitutes you one people is also now dear to you. It is justly so, for it is a main pillar in the edifice of your real independence, the support of your tranquility at home, your peace abroad; of your safety; of your prosperity; of that very liberty which you so highly prize. But as it is easy to foresee that, from different causes and from different quarters, much pains will be taken, many artifices employed to weaken in your minds the conviction of this truth.  George Washington - Farewell Address

"Scientists" would sound the alarm on cricket farts if they thought there was some money in it. :tongue2:
