In Canada, two earthquakes with a magnitude of 6.0 occurred. The epicenters were off the west coast near Vancouver Island. The depths of the epicenters are estimated at 10 km. Before the two main impacts, there was a somewhat weaker quake with M 5.7. An aftershock brought it to M 4.7. There are no reports of damage.
The quakes probably manifested themselves in a fault between the spreading zone of the Juan-de-Fuca-Ridge and the Cascadia subduction zone. Many severe earthquakes have already occurred in the region. It is one of the most seismically active areas on earth. Further south lies the US metropolis of Seatlle. A strong earthquake has long been expected there at the Cascadia subduction zone.
