...Allison L. Bent Abstract The 1 March 1925 Charlevoix earthquake is one of the largest earthquakes known to have occurred in southeastern Canada. Because it occurred in one of the most active seismic zones of southeastern Canada, and near now heavily populated regions, understanding this earthquake...

... range of 5.5–6.0. After corrections for epicentral‐distance differences are applied, the modified Mercalli intensity ( MMI ) data for the 1870 earthquake and for the moment magnitude M 6.2 Charlevoix earthquake of 1925 at common sites show that on average, the MMI readings are about 0.8 intensity units...

...Ronald Doig Abstract Silt layers in organic-rich lake sediments are interpreted to represent the historic earthquakes of 1638, 1663, 1791, 1870, and 1925 of the Charlevoix region of eastern Canada. This interpretation is based on the relative spacing of the layers and the accelerator-mass...

.... The felt area exceeds 3.5 million km 2 and closely approaches that of the 1925 Charlevoix earthquake. The location of the Saguenay event in a region with little historic seismicity, its depth, and its large high-frequency generation, pose several problems for existing models of seismic zoning and hazard...
