|Abstract||This is the second in a series of papers intended to describe the entire known earthquake history of eastern Canada. The area considered embraces northeastern North America and its adjacent waters east
of longitude 85° W and bounded by the 40th and 60th parallels.|
The two lists in the earlier paper, one of earthquakes in eastern Canada and the other of those in the northeastern United States, have been continued. From 1928 to 1959 there were 405
shocks in eastern Canada and 312 in the northeastern United States. To 1959 the shocks total 743 in the Canadian lists and 729 in the United States lists. Each list is accompanied by a geographical index.
Either an intensity or a magnitude has
been assigned to each shock, and a linear relation between these scales has been accepted. All earthquakes are shown on the maps by symbols proportional to their sizes regardless of the scale on which these sizes are expressed. lsoseismal maps of six
of the larger earthquakes have been included.
In general, only essential information about each shock is given, but a number of the Canadian entries are annotated and striking or unusual features of all the important shocks have been included.
After each entry in the text all the sources of information consulted are indicated by letters and numbers, which can be readily identified in the references.
