Authorities said tsunami waves would reach Oregon and warned coastal residents to avoid shorelines but said it was "not a major tsunami."

Tsunami waves reached the U.S. West Coast after a massive earthquake off Russia, prompting warnings in California, Oregon, and Washington.

A tsunami warning has been issued for parts of California and Oregon, meaning residents are urged to move away from the coast or to high ground. The National Oceanic and Atmospheric Administration (NOAA)'s alert system issued the warning about 11:20 p.
