Revised epicenters for large historical earthquakes in Baffin Bay [electronic resource] / A. Bent. [Ottawa] : Natural Resources Canada, 1998. 44 p. : charts, maps Open file ; 3644 Historical publication digitized by the Geological Survey of Canada. "1998." Includes bibliographical references (p. 8). "Accurate epicentral locations can provide information about fault orientations and seismotectonic processes in the regions in which the earthquakes occur. Since 1933 there have been five earthquakes of magnitude 6.0 of greater, including one of magnitude 7.3, beneath Baffin Bay. Current earthquake catalogs generally place these earthquakes at locations published in the International Seismological Summary (ISS) bulletins. However, the epicenters for two of these events appear to have been fixed at the epicenters of previous events and all are based on an outdated model of the Earth's interior. In this study, the five largest Baffin Bay earthquakes have been relocated using a modern Earth model and path corrections (determined in this study) for the stations that recorded the events. Several epicenters were changed by tens of km, although all still fall within the boundaries of the Baffin Bay seismic zone. This paper discusses the relocation of these events and tabulates all arrival time and station correction data used in the procedure"--Abstract, p. 2.
