“This potential problem was first raised a few years ago when a crack appeared along the ridge peak of the island.
Now it has grown some and the swarm of earthquakes could easily dislodge the unstable western wall of the volcano causing it to slip into the ocean creating a mega tsunami, which would target Florida, Georgia, the Carolinas, NY etc as far as Nova Scotia.
