      After significant seismic activity off the B.C. coast in December, another offshore quake has taken place—but this time off southern Vancouver Island.

      An earthquake struck at 1:35 p.m. (Vancouver time) today (January 24) off the southwestern coast of Vancouver Island.

      Earthquakes Canada initially reported it as a 4.0-magnitude quake before revising it to 4.4-magnitude.

      Meanwhile the U.S. Geological Survey initially measured it as 4.5-magnitude before reassessing it as 4.8-magnitude, then revising it back to 4.5-magnitude again.

      The epicentre of this one was originally reported by the U.S. Geological Survey at a shallow depth of four kilometres (two miles) but was revised to 26 kilometres (16 miles) before changing to 10 kilometres (six miles).

      It was centred 29 kilometres (18 miles) southwest of Bamfield, B.C.; 46 kilometres (29 miles) northwest of Neah Bay, Washington; 89 km (55 miles) southwest of Port Alberni; 139 kilometres (86 miles) west of Victoria; and 175 kilometres (109 miles) southwest of Vancouver.

      Earthquakes Canada stated that it was lightly felt on Vancouver Island and in Metro Vancouver, but there were no reports of damage and none are expected. A tsunami is also not expected.
