static map showing earthquakes highlighted in this list
Notes:
- Older historical (particularly pre-20th centtury) earthquakes were not instrumentally recorded, their locations and magnitudes are evaluated from felt reports and descriptions of damage.
- In some earthquake catalogs, an earthquake is reported to have occurred between the two voyages of Jacques Cartier during the summers of 1534 and 1535, respectively. According to P. Gouin (1994), this entry is based on a Huron oral tradition which states that before 1637, an earthquake was felt in Old Huronia (Georgian Bay Region). P. Gouin (1994) showed that the 1534-1535 event was entirely fictitious and, consequently, should be removed from earthquake catalogs. (Pierre Gouin, 1994. About the first earthquake reported in Canadian history, Bulletin of the Seismological Society of America. 84; 2, Pages 478-483).
- In some earthquake catalogs, the 11 June 1638 earthquake is associated with the Charlevoix region. This association is erroneous since this earthquake is thought to have occurred in New England, possibly near Boston or Plymouth, Massachusetts (Stevens, A.E. 1995. Eastern North American Earthquakes prior to 1660. Bull. Seism. Soc. Am., 85, 1398-1415).
