Canada Day quake big­ger than ini­tially recorded

Cape Breton Post - - PROVINCE -

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.
