After a series of earthquakes hit off the west coast of Vancouver Island on Sunday night, a seventh earthquake has been reported this morning 225 km west of the town of Tofino, and 419 km west of Victoria.
Last night, reports came in of three earthquakes of a 6.5 magnitude or higher occurring, all within an hour of each other, off the BC coast. A fourth earthquake took place at 11:36 pm PST, with a magnitude of 4.9 and a deeper depth of 17.8 km.
Since then, two more earthquakes have struck near the same area, on the Explorer seismic plate.
Both were significantly smaller than their predecessors, one of a magnitude 4.3 taking place at 12:30 am (PST), and another of 4.4 at 1:43 am (PST), on October 22. Both were over 200 km from Port Hardy, BC. And each took place at a depth of around 10 km, the same depth as the three 6.5+ earthquakes.
According to the US Geological Survey, the first earthquake struck at 10:39 pm (PST) with a magnitude of 6.6, followed by a magnitude 6.8 at 11:16 pm and, minutes later, (11:22 PST) a third earthquake hit with a magnitude of 6.5.
Another earthquake took place at 11:36 pm PST, with a magnitude of 4.9 and a deeper depth of 17.8 km.
According to a tweet released by the US National Tsunami Warning Center, a government agency that monitors and issues tsunami information for the continental US and Canada, no tsunami is expected. They issued individual alerts for each event.
