Fereidoni and Atkinson (2014) analyzed the aftershock sequences of four M≥4.5 earthquakes that occurred in eastern Canada from 1982 to 2010 to estimate the Omori‐law parameters for those aftershock sequences. They then used this information to assess the modern rate of aftershocks of the 1663 earthquake in the area of Charlevoix, Quebec. When they compared the estimated aftershock rate with the observed rate of modern seismicity at Charlevoix, they reported that the observed modern earthquake rate is higher than that predicted even using the Omori‐law parameters from the most active aftershock sequence in eastern Canada that they analyzed. From...
