A preliminary LCSN moment tensor solution for the event on 03/06/2005 at 06:17:49 UTC located at 17 km SW of Riviere-du-Loup, QC, Canada. Location: 47.76N 69.69W, h=15 km, LCSN A moderate earthquake occurred in the Charlevoix seismic zone in Quebec, Canada. Moment magnitude, Mw 4.7, and focal depth of 15 km were obtained from analysis of long period waves recorded by 21 stations of the Canadian National Seismic Network (CNSN), Lamont-Doherty Cooperative Seismographic Network (LCSN) and U.S. National Seismic Network (USNSN) stations in the region.
