VANCOUVER, British Columbia (Reuters) - The Queen Charlotte Islands off Canada’s Pacific Coast were rattled by the third strong undersea earthquake in less than a week on Wednesday, but no damage or injuries were reported.

The 6.1 magnitude quake was centered about 185 km (116 miles) south-southeast of Queen Charlotte City, British Columbia, and 626 km (391 miles) northwest of Vancouver, according to Environment Canada.

It did not prompt a tsunami warning.

The earthquake-prone region was hit by two 6.5 magnitude undersea quakes on Saturday, neither of which caused damage in the relatively unpopulated area.
