Canada 서해(西海)의 Seismicity

Seismicity of the offshore area of western Canada

This paper examines the seismicity of the offshore area of western Canada in the light of findings from a detailed study of an earthquake swarm which occurred in the area during November-December in 1971. The distribution of epicenters and focal mechanism solutions of a few main events suggest that the seismicity of the area may largely be interpreted in terms of plate interactions among the Pacific, Juan de Fuca, Explorer and North American plates. Differences between the patterns of seismicity along the transform fracture zones and at their junctions with the ridges were also observed.
