Summary of earthquake history and assessment of new events / J. Adams. St. John's, Newfoundland, newspapers between 1810 and 1914 were systematically scanned for reports of earthquakes which had been felt but not previously catalogued. No new earthquakes were discovered in this period. The newspapers and other sources were searched to refine the location and size of previously catalogued earthquakes. Three new earthquakes were found: 11 April 1930 magnitude 3.6 near Ramea, 05 January 1956 magnitude 3.5 near Heart's Content, and 28 January 1957 magnitude 3 near Grates Cove. Significant reports were found to modfify the paramaters of four other known earthquakes. Reports confirming the non-seismic nature of some suspicious events were also found. The confirmed events, together with the high level of earthquake awareness evidenced, confirm the low level of local seismicity observed since the region was closely monitored by seismographs.
