| Abstract | 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. |
| Summary | (Plain Language Summary, not published)
This report summarizes regional centroid moment tensor solutions for eastern Canadian earthquakes of magnitude 4.0 or greater for the period 2011-2013.
These solutions provide focal mechanism (fault orientation and slip direction), depth and seismic moment (best measure of earthquake size), all of which have implications for seismic hazard and help improve our understanding of the seismotectonic
environment in which the earthquakes occur. These solutions are expected to provide input into future research projects. |
