Top of Page Earthquakes in Canada Major Earthquakes in Canada - 20th century Seismologists estimate that more than 1,000 earthquakes are recorded each year in Canada. Most of these measure less than magnitude 3 on the Richter scale and are not felt by humans. Earthquakes of magnitude 6 or greater are strong enough to cause significant damage.
Seismographs are instruments used to record and measure earthquakes.
During an earthquake, vibrations initiated by fracturing of the earth's crust radiate outward from the point of fracture. Seismographs detect and record these vibrations for further study. The visual record produced by a seismograph is called a seismogram. Eastern Canada is located in a stable continental region of the North American Plate, and as a consequence, has a relatively low rate of earthquake activity. Nevertheless, large and damaging earthquakes have occurred here in the past and will inevitably occur in the future.
