Mount Etna is sliding four centimeters in eight days. COULD TRIGGER A TSUNAMI

Описание: Mount Etna is sliding four centimeters in eight days. COULD TRIGGER A TSUNAMI

Mount Etna's eastern flank is sliding toward the Ionian Sea at approximately fourteen millimeters per year — and the process is directly tied to hydrothermal vent stability on the seafloor. In this video, we break down the science behind one of the most closely monitored geological phenomena in the world.
🔍 In this video you will discover:
✅ Why gravity — not magma — is the main force driving Etna's displacement
✅ What the first-ever seafloor geodetic monitoring campaign revealed in 2017
✅ How the January 2026 flank eruption and the magnitude 5.3 Ionian earthquake fit into this picture
✅ The connection between fault creep, hydrothermal discharge, and seafloor ecosystems
✅ What a catastrophic flank collapse would mean based on geological evidence from 8,000 years ago
The Helmholtz Centre for Ocean Research in Kiel deployed underwater acoustic transponders along Etna's offshore fault line and recorded a four-centimeter slip in just eight days during May 2017. That data redefined how scientists understand the volcano's movement — and raised new questions about what happens to the hydrothermal systems below the Ionian Sea if that displacement accelerates.
