Juneau, AK – A powerful offshore earthquake struck northwest of Juneau this afternoon, but officials emphasize that the U.S. West Coast faces no tsunami danger from the event. The preliminary magnitude 7.0 quake was reported around 12:42 p.m. PST, according to the National Weather Service (NWS) office in Eureka, California.
According to the agency, the earthquake occurred approximately 230 miles northwest of Juneau in a region of the Gulf of Alaska known for deep, offshore seismic activity. Because of its location and depth, the quake did not generate the type of ocean displacement required to trigger tsunami conditions.
The National Tsunami Warning Center (NTWC) confirmed shortly after the quake that no warnings, watches, or advisories were issued for coastal areas in California, Oregon, or Washington. Monitoring buoys along the Pacific showed no unusual wave activity, officials said.
While the quake was strong, early impact reports from Alaska indicate no major damage or injuries. Seismologists note that large offshore quakes in this region occur periodically and often do not create tsunami hazards unless significant vertical seafloor movement is detected—something not observed today.
Residents along the West Coast are encouraged to remain aware of official alerts but are not being asked to take any protective action. Officials also remind the public that aftershocks may follow, though they are unlikely to affect the tsunami outlook.
