Regional centroid moment tensor solutions for eastern Canadian earthquakes: 2011-2013

Regional centroid moment tensor solutions have been determined for twenty-eight moderate-sized earthquakes in eastern Canada for the period 2011-2013. Three other earthquakes were evaluated but good quality solutions could not be obtained. The moment tensor inversion method is used to determine the focal mechanism, depth and seismic moment of the earthquakes. These parameters, in turn, provide information about the seismotectonic environment in which the earthquakes occur and may help improve seismic hazard estimates. The purpose of this paper is not to provide an in-depth analysis of any specific earthquake but to catalog the solutions and data used to obtain them to make them available for future research projects.
