AI Discovers 73 Hidden Volcanic Calderas Beneath the Oceans

Scientists just used artificial intelligence to uncover 73 hidden volcanic calderas beneath our oceans, a discovery that more than triples the number of known underwater volcanic craters.

Volcanologist Andrea Verolino and her team at Paris-Saclay University borrowed an AI system originally built to spot impact craters on Mars and pointed it at Earth's seafloor instead. The algorithm scanned underwater maps and flagged over 87,000 possible formations.

After filtering out false alarms and conducting manual reviews, the team confirmed 78 likely calderas. Five were already known, but 73 were completely new to science.

Calderas form when a volcano's magma chamber empties and the ground above collapses, creating massive craters. While many are remnants of dead volcanoes, some are just dormant, which makes this discovery particularly valuable for safety planning.

These newly found calderas are scattered across the globe, with most located far from tectonic plate boundaries in underwater mountain chains called seamounts. The team published their findings in Communications Earth & Environment.

Why This Inspires

This discovery shows how technology designed for space exploration can solve mysteries right here at home. By repurposing Mars-hunting AI for Earth, scientists demonstrated that innovation in one field can spark breakthroughs in another.

The research team has already flagged seven calderas for immediate follow-up based on their size, depth, and location. While they're not claiming these specific calderas are active, recent studies show that even supposedly dead volcanoes can slowly refill with magma over centuries.

Understanding where these underwater volcanic features exist helps scientists better predict potential hazards like tsunamis, shock waves, and massive steam explosions that can result from caldera eruptions. The more we map our ocean floor, the better we can protect coastal communities worldwide.

This breakthrough proves that artificial intelligence isn't just transforming how we explore distant planets. It's helping us understand the 71% of our own planet that lies hidden beneath the waves, making Earth a little less mysterious and a lot safer.
