Newsprepper.com reports: According to the data buoy, the water column height (depth) fell sharply within minutes off the coast of Oregon, signaling the land beneath the ocean has suddenly "sunk." Here are the graphs showing what the ocean data buoy recorded: As of 0231:30, the initial water column height is 2738.80 Meters deep (8985.56 feet).
