Canada Day quake bigger than initially recorded
It turns out a Canada Day earthquake that struck southwestern Nova Scotia the afternoon of July 1 was actually a 3.8 magnitude earthquake, as opposed to a 3.6 one that Earthquakes Canada had initially recorded it as.
Although a weak earthquake, at 3.8 it was still one of the top 5 ‘strongest’ magnitude earthquakes recorded in Canada over a 30-day span, which saw around 315 earthquakes recorded. The majority of earthquakes in Canada (and there are about 10 to 20 each day) are so small no one — other then those who record data on them — knows they occurred.
For instance there were two other earthquakes in June in the Digby region — a 2.5 and a 2.9 — that went unnoticed by the public.
During the month of June the highest magnitude quake in Canada was a 4.4 quake recorded 155 km northeast of Jasper, Alberta, on June 13. That quake resulted in no damage. Even at that magnitude, says Earthquakes Canada and Natural Resources Canada, no damage would be expected.
In June there were two 3.9 earthquakes recorded — one in Nunavut and one in British Columbia. In addition to the 3.8 magnitude earthquake recorded in this region on July 1, there was also a 3.8 quake in Quebec on June 28. It isn’t until you reach quakes of magnitude 6 or higher that you start to see any significant damage, according to Earthquakes Canada.
