Unseen Threat: Hidden Volcanoes More Dangerous Than Famous Ones

• Scientists warn lesser-known, "hidden" volcanoes pose the highest global risk due to poor monitoring and underestimation.
• While famous volcanoes are closely watched, many dangerous ones like Toba, Taupo, and Hayli Gubbi remain largely unmonitored, some dormant for millennia.
• Less than half of Earth’s active volcanoes are fully monitored, lacking crucial sensors, making eruptions harder to predict.
• Recent eruption of Ethiopia’s Hayli Gubbi after 12,000 years of dormancy highlights the sudden reactivation risk.
• A major eruption from these hidden systems could cause global ash spread, climate cooling, air travel disruption, and food/water crises, requiring urgent global monitoring.

Why It Matters: Unmonitored hidden volcanoes pose a catastrophic global threat, demanding urgent monitoring and preparedness.
