western Quebec seismic zone and 8.2 km for the southern Ontario seismic zone. Focaldepths higher than 18 km are observed for 24 events in the region, which reflects thedepths for clusters of seismicity in the western Quebec (near the St. Lawrence River).Events with shallower depths are mainly located in Southern Ontario Seismic Zone.Figure 4.2: Distribution of focal depths for the events in a) Southern Ontario, andb) Western Quebec.47
