This is more an FYI than a warning for L.A. at this point, since no giant waves have been spotted.
But an 8.0 earthquake hit the south Pacific seabed near Tonga, Samoa and Fiji causing the National Weather Service to issue a tsunami warning for Fiji, New Zealand and Hawaii.
the warning center said the earthquake, based on historical records, was not sufficient to generate a tsunami damaging to the Pacific coasts of the United States and Canada, and Alaska. Some areas may experience small sea-level changes.
