The increasing knowledge of general seismicity patterns in northern Canada follows the expansion of the Canadian seismograph network in the north. Most large and major earthquakes in this century have been located, but there is only a partial record of moderate earthquakes. A knowledge of minor earthquakes in northern Canada begins only in the early 1960’s because of a previous lack of suitable recording stations. Examples of recent seismic activity on Baffin Island, on Prince Patrick Island, northeast of Melville Island and in the northeastern Yukon illustrate that present earthquake locations delineate areas of significant seismic activity but in general are not known with sufficient accuracy to be used to map active faults. In northern Canada the known seismic history is too short to predict that new areas of significant seismic activity will not occur in the foreseeable future.
