"The Charlevoix Seismic Zone northeast of Quebec City is one of the most active seismic zones in eastern Canada and the seismograph station density is higher than in most other regions of eastern Canada. These two factors combined make it an ideal region for comparing earthquakes of different magnitudes and for comparing the same earthquake at local and regional distances. Using data from the Charlevoix region we develop magnitude conversion relations between magnitudes recorded at distances of less than 50 km and the standard MN magnitude based on the Lg phase"--Introduction, page 4.
