Revised seismicity of the Grand Banks and offshore Newfoundland / John Adams and Rutger Wahlström.: M183-2/3043E-PDF
A comprehensive reivew of the catalogued seismicity of the Grand Banks of Newfoundland (1922-1994) has revised or added earthquakes in four time periods: 1922-1970, the two largest earthquakes (M≈5) relocated to Baffin Island (1992) and the northern Labrador Sea (1962); 1977-1982, added four new earthquakes; 1969-1984, revised the locations and magnitudes for five earthquakes; 1984-1994, added 15 earthquakes. Many earthquakes appear to be spatially associated with Mesozoic extensional structures that trend northeastwards across the Grand Banks. A cluster of six pos-1970 earthquakes lies 40-80 km northwest of the Hibernia oilfield and represents the most seismically active region of the Grand Banks.
