Abstract
Canadian studies in paleoseismology have led to the publication of over 40 papers in the last 12 years, 80% of which have appeared since 1989. Considerable progress has been achieved by confirming that the last great earthquake on the Cascadia subduction zone happened about 300 years ago and by working toward a chronology of prior earthquakes from their tsunami and turbidite records. As-yet-sparse evidence suggests that the geological effects of large crustal earthquakes are also recorded in southwestern British Columbia, but there is as yet no chronology. In the stable craton of eastern Canada, studies of silt layers in lakes that are floored by organic sediments have shown considerable potential to provide local earthquake chronologies that can be tested against the more sporadically preserved evidence from liquefaction, landslides and other possible indicators of paleoshaking. By contrast, research using more traditional techniques, involving direct examination of faults through geomorphological studies or trenching, has been hampered by the difficulty of identifying active faults in the first place. On the basis of the past dozen years, an accelerating pace of discovery should be expected in the next decade.
