"No destructive widespread threat exists based on historical earthquake and tsunami data, NWS reported following the evaluation, adding earthquakes this size can generate local tsunamis that can be destructive along coastlines near the quake's epicenter.
There is currently no tsunami threat for Washington, Oregon or Hawaii, reports NWS.
If you are in a warning area, move inland to higher ground, be on alert to instructions from local emergency officials, do not go to the coast to observe the tsunami and do not return to the coast until local officials indicate that it is safe to do so, according to the center.
Since 5: 30 p.m. EDT, four aftershocks in the region have been reported by the USGS. The National Tsunami Warning Center will continue to update and evaluate the event.
