Magnitude 4.3 earthquake strikes near Queen Charlotte Village
Earthquakes Canada and U.S. Geological Survey downgrade earlier estimates of magnitudes 4.8 and 5.0
A small earthquake has struck 88 km south of the Village of Queen Charlotte in Haida Gwaii according to the U.S. Geological Survey.
Initially the two major earthquake measuring services, the U.S. Geological Survey and Earthquakes Canada put the magnitudes of the early Sunday afternoon quake at 5.0 and 4.8 respectively.
However, by late Sunday afternoon, both estimates were downgraded with the USGS settling on magnitude 4.3.
The earthquake struck at a depth of 19 km around 1:10 p.m. PT according to both earthquake reporting services.
Earthquakes Canada says early reports indicate the quake was not widely felt and there is no danger of a tsunami.
Earthquake latest in a series
Sunday's shaker is the latest in a series of recent quakes to strike the B.C. coast including a magnitude 4.8 earthquake near Tofino, B.C. Jan 7 that, unlike this one, was widely felt, rattling homes and causing lamps to sway in the Tofino area.
The previous week on Jan 2 and 3rd separate earthquakes of magnitudes 5.2 and 4.5 were reported 200 km off the coast of Port Hardy. Like today's earthquake, neither of these was widely felt.
A swarm of five earthquakes also struck further west of Port Hardy in late December, at depths ranging from 10 to 22 km.
According to the Geological Survey of Canada, these clusters are larger than normal, but not unusual, nor do they effectively increase the risk of the "big one."
Seismologists say these quakes are occurring within the overriding North America plate, although, these smaller quakes can occasionally be damaging because of their shallower depth.
Experts say the so-called "big one," a damaging megathrust earthquake, will occur within the Juan de Fuca plate which has become stuck trying to move under the North American plate — a completely different location than where the current earthquakes are occurring.
