Three major earthquakes, ranging between 6.5 and 6.8 in magnitude, occurred in less than 60 minutes off the coast of Vancouver Island in British Columbia.

There were no immediate reports of damage, and the Pacific Tsunami Warning Center issued no tsunami warnings for any of the three earthquakes.

Due to the location and depth of the earthquakes, the United States Geological Survey (USGS) only expects light shaking to be felt, and did not forecast any damage to occur.

Three earthquakes of that magnitude within such a short period is rare, but not unheard of.

Fortunately, all three quakes were located offshore, limiting the risk for damaging impacts to land.

Three aftershocks with magnitudes ranging from 4.3 to 4.9 were reported within hours of the initial three powerful quakes.

Canada’s western coastline sits along the the Ring of Fire, a 25,000-mile (40,000 km) arc of fault lines and more than 400 active volcanoes that run from the South Pacific Ocean to Alaska, and then southward along the western coastline of North and South America.
