According to information released from the U.S. Coast Guard:
The U.S. Coast Guard is currently searching for a person in the Pacific Ocean waters near the Klamath River. A man was swept out to sea by a wave after he and two friends reportedly traveled to the shoreline to take photos of the incoming tsunami waves generated by Friday’s earthquake off of the coast of Japan. Two of the men were able to get back to shore and one is still unaccounted for. The Coast Guard is currently searching for the man with MH-65C Dolphin helicopters from Air Station Humboldt Bay.
The Coast Guard strongly recommends staying clear of low lying coastal areas during periods of tsunami warnings.
