Three earthquakes up to magnitude-4.2 and nearly a half-dozen aftershocks have jolted northern Idaho, with residents from Washington state to Montana saying they felt the tremors.

A Bonner County emergency dispatcher in Sandpoint said Friday morning that no injuries or damage were reported.

The U.S. Geological Survey says a magnitude-4.1 quake hit first, around 7:32 p.m. Thursday. It was centered 30 miles northeast of Hayden.

A second quake of magnitude-4.2 struck a little more than three hours later and was centered 38 miles northeast of Hayden. A magnitude-3.3 temblor hit at 1:28 a.m. Friday in the same area.

Hundreds of people logged onto the Geological Survey's National Earthquake Information website to report feeling the quakes.
