Focal depth of earthquakes of the St. Lawrence Valley based on crustal phases recorded within 100 km epicentral distance / M. Lamontagne.

"We have computed the focal depth of 53 earthquakes of the St. Lawrence Valley (defined as latitudes 45ºN to 47ºN and longitudes 70ºW to 75ºW) between Montreal and Quebec City using a minimum of six Pg and Sg phases from three seismograph stations or more located within 100 km of each epicentre. In addition, the epicentre had to be within the polygon defined by the seismograph stations (i.e. the azimuthal gap had to be less than 180º). Although all 607 events of the period 1980-2015 inclusively were considered, the majority of selected events were in the period 2013-2015 when the USARRAY stations occupied the region of interest"--Abstract, page 3.
