| Abstract | Regional centroid moment tensor solutions have been determined for seven moderate-sized earthquakes in eastern Canada during 2017. Two 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. 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)
Regional centroid moment tensor solutions have been determined for seven moderate-sized earthquakes in eastern Canada during 2017. The moment tensor
inversion method is used to determine the focal mechanism (style of faulting), depth and seismic moment of the earthquakes. These parameters provide information about the seismotectonic environment in which the earthquakes occur and may help improve
seismic hazard estimates. The purpose of this report is to catalog the solutions and data used to obtain them to make them available for future research projects |
