What would happen if large asteroid hit the ocean? For starters it would cause massive waves that could inundate U.S. coastlines, a new computer simulation suggests. It shows that it that if it hit the east coast it could produce 23-foot-high (7 meters) waves, causing flooding from New York to Georgia that would take hours to recede. A similar impact off the coast of California could flood major power plants along the coast, the research also suggests.
Keep in mind that the moon was created by a single giant impact event. Then, Earth’s size attracted huge meteorites, which slammed into it, causing super-high-temperature rock vapor to cover the entire surface and evaporate all ocean water.
In this video watch what would happen if an asteroid hit the Earth with this detailed “Large Asteroid Impact Simulation”. An asteroid with a diameter of 500 km. Destination: The Pacific Ocean. The impact peels the 10 km crust off the surface. The shockwave travels at hypersonic speeds. Debris is blasted across into low Earth orbit and returns to destroy the surface of the Earth. The firestorm encircles the Earth, vaporizing all life in its way. Within one day, the surface of the Earth is uninhabitable. The evidence shows that this has happened at least six times in Earth’s history.
