718 NEW MASSIVE CRACK under Atlantic could spark devastating Earthquakes and TSUNAMIS soon

This phenomenon, previously thought impossible, could explain Europe’s largest earthquakes, including the devastating 1755 Lisbon earthquake. The study utilised seismic images and computer simulations to discover the first evidence of a large ocean plate sinking into the mantle, challenging existing geological theories.A new hypothesis, “takeoff,” explains the presence of a deep oceanic lithosphere slab without corresponding crustal shortening. This slab, formed from a serpentinised oceanic lithosphere, is detaching from the crust due to pre-existing faults and a lubricating serpentinised layer. This process, confirmed by simulations, could explain the Lisbon earthquake and potentially initiate a new subduction zone, eventually consuming the Atlantic Ocean floor.
