AbstractRegional centroid moment tensor solutions have been determined for five moderate-sized earthquakes in eastern Canada during 2016. Four additional earthquakes were also evaluated but their solutions did not meet the minimum quality standards for acceptance. 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. Focal mechanisms determined from first motions for four small earthquakes in New Brunswick are also included. The purpose of this report 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 paper, covering the year 2016, is one in a series of annual reports summarizing regional moment tensor inversions for eastern Canada. Moment tensor inversions provide information about focal mechanisms (fault parameters), depths and magnitudes. These parameters have implications for seismic hazard assessment and regional seismotectonic studies.
