AI Search Uncovers 73 Unknown Submarine Calderas After Screening 87,435 Seafloor Features

2 articles · Updated · ScienceAlert · Jul 6

Summary

  • 73 previously unknown submarine calderas were identified by Andrea Verolino's team after an AI-assisted scan of global bathymetric maps, in a finding that would more than triple the documented total if confirmed.
  • 87,435 possible formations were initially flagged by an algorithm adapted from Mars crater detection, then narrowed to 78 likely calderas through filtering and manual review; five were already known examples.
  • 61 of the new candidates lie in interior tectonic settings, with nine in volcanic arcs and eight at mid-ocean ridges, giving researchers a clearer picture of where these hidden volcanic systems cluster.
  • Seven of the newly identified calderas were singled out for follow-up because their depth, shape and location could make them important for understanding submarine eruption and tsunami hazards.
  • The study did not judge whether any site is active, but the authors say the dataset closes a major observational gap and offers a reproducible baseline for future global volcanic risk assessments.

Discovery of 73 New Submarine Calderas by AI Redefines Global Volcanic Risk

Overview

A groundbreaking discovery by Andrea Verolino's team has revealed 73 previously unknown submarine calderas, fundamentally changing our understanding of underwater volcanic landscapes. These calderas, formed when a volcano's underground magma chamber empties and the ground collapses, highlight the vast and dynamic nature of the seafloor. The identification of so many new calderas means scientists must re-evaluate volcanic maps and models, especially for submarine volcanism. Each caldera could be a site of past or future volcanic activity, so further investigation is needed to determine if they are dormant, active, or extinct, with important implications for global volcanic hazard assessment.
