EUGENE, Ore. - The Pacific Tsunami Warning Center said a magnitude 7.3 earthquake off the coast of Japan does not pose a hazard to Hawaii or the West Coast of the United States.
The earthquake offshore of Honshu, Japan, occurred as the result of normal faulting in the shallow oceanic crust of the Pacific plate, the U.S. Geological Survey reports.
The earthquake occurred east of the Japan Trench, "up-dip" from the source of the March 2011 9.0 earthquake that triggered devastating tsunamis in Japan. Tsunami waves from that quake also damaged ships and killed at least one person on the US West Coast.
