A comparison of seismicity to the crustal deformation predicted by a glacial isostatic adjustment model in northern Canada and western Greenland / T.S. James and T.D. Schamehorn. : M183-2/8106E-PDF

"The stretching and squeezing induced by glacial isostatic adjustment (GIA) in northern Canada and western Greenland is compared to the spatial pattern of earthquakes to determine whether earthquakes occur where GIA-predicted crustal strain-rates are high. For the comparison, an updated seismicity catalogue was created from two previously-existing catalogs. Crustal motion rates were computed for a recently published GIA model that simulates the Earth's response to the last Ice Age. This GIA model fits sea-level and vertical crustal motion observations better than previous models. A region in Baffin Bay where predicted GIA strain-rates are high also features historically high seismicity, including the 1933 M 7.4 and the 1934 and 1945 M 6.5 earthquakes. Elsewhere, agreement is not strong. Suggestions are made for further investigations"--Summary provided by publisher.
