A major 8.2 earthquake off the northern coast of Chile just generated at least a six-foot tsunami in the South American country. If the tsunami continues out into the open Pacific, it will reach Hawaii in about 13-14 hours. There probably won't be a tsunami in Hawaii.

As part of a nationwide campaign to ready coastal residents for the possibility of a tsunami on American shores, the National Weather Service included areas along the Gulf Coast in the week's readiness activities.
