Boise, Idaho -- A series of shallow earthquakes have been startling residents from Oregon to Idaho and even as far way as Alaska.
In the Gem State, the strongest shaking was felt just east of Pocatello.
The tremors, all of which are a 4.0 magnitude or less, have been occurring along the Blanco Fracture Zone off the Oregon Coast.
Emergency managers say the quakes are no cause for alarm but shouldn't be handled with absolute complacency either.
"Future activity cannot be predicted, however people living anywhere in the Pacific Northwest could potentially experience a magnitude 5 or 6 earthquake. Planning is not a prediction, but planning for the worst and hoping for the best is good advice in the disaster preparedness profession," said Susan Reinertson, FEMA's regional administrator.
Emergency managers say all Americans should have a 72 hour disaster preparedness kit with food, water, prescription medication and first aid supplies in their homes.
