A preliminary LCSN moment tensor solution for the event located at 60 km North of Medina, NY; 30 km S from Port Hope, ON, Canada (43.70N, 78.25W, h= 5 km, ML=3.3; LCSN; Mn=3.8 GSC) on 08/00/2004 at 23:55:26 UTC. Mw 3.1 and depth of 5 km were obtained from long period waves recorded by POLARIS (Portable Observatories for Lithospheric Analysis and Research Investigating Seismicity) stations in Ontario, Canada; CNSN stations (SADO, KGNO), USNSN (BINY) and LCSN (ALLY) stations in the region.
