PALMER -- A magnitude 6.6 earthquake occurred at 7:30 a.m. Tuesday off the Queen Charlotte Islands on the west coast of British Columbia.

A spokesman at the Tsunami Warning Center in Palmer, Guy Urban, said it did not generate a tsunami. He said the quake was reportedly felt in Port Hardy and Prince Rupert, B.C. No reports of damage.

Urban said it was followed six minutes later by a 5.7 magnitude aftershock.

He says such quakes in that remote area are "not unusual."
