You may not have felt them, but two small earthquakes occurred off Vancouver Island Friday afternoon and early Saturday morning.
According to a social media post by John Cassidy, earthquake seismologist for National Resources Canada, the first minor quake occurred on April 9, on the northwest coast of the Island and registered as a 1.5-magnitude quake.
He noted that no one had reported feeling the “tiny earthquake,” but that it was a reminder that the Island is “an active seismic zone” and that even the smallest earthquakes can be detected.
No one felt this afternoon's tiny (M~1.5) earthquake on the west coast of #VancouverIsland, but it is a reminder of an active seismic zone and that we can easily detect earthquakes that are too small to be felt in this region.— John Cassidy (@earthquakeguy) April 9, 2021

The second quake occurred just after 12:30 a.m. on April 10. The 3.0-magnitude earthquake was also located on the west coast of the Island, but closer to Ucluelet and Bamfield, Cassidy reported.
