    Thursday, January 8, 2015, 4:28 PM - Residents of Vancouver Island experienced rattling picture frames and shaking windows Wednesday evening after a 4.8 magnitude earthquake struck 18 kilometres east-northeast of Tofino.

    There were no reports of injuries or significant damage, and tsunami warnings were not issued over the 'quake which measured at a depth of 24 kilometres.

    The earthquake is the latest in a series to strike off the B.C. coast.

    Last Friday and Saturday separate earthquakes with respective magnitudes of 5.2 and 4.5 struck 200 km off the coast of Port Hardy at the northern end of Vancouver Island.

    A group of five earthquakes also struck west of Port Hardy further in late December, at depths ranging from 10 to 22 km.

    But according to the Geological Survey of Canada, these clusters are larger than normal, but not unusual, nor does it effectively increase the risk of the "big one."

    The series of maps below depict the Wednesday shaker and explain the tectonics of the affected area:
