[Rockhounds] Global supervolcano threat rises as scientists sound the alarm

[Kreigh Tomaszewski]

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
<https://en.wikipedia.org/wiki/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.
