An 8.9 magnitude earthquake off the coast of Japan has triggered a tsunami warning for the U.S. West Coast with an estimated time of arrival of 8:08 AM in San Francisco.
Keep in mind that the “arrival time” is for the initial wave which is not necessarily the largest, wave activity would actually peak a few hours after arrival, and the warning does not indicate an imminent tsunami but better safe than sorry.
