[2] The earthquake occurred at 5:30 p.m. local time and was estimated to have a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale.

The Great New England Earthquake of 1663, also known as the Charlevoix Earthquake, started along the Saint Lawrence River, between the mouths of the Malbaie and Ouelle rivers. Geologists estimate it measured 7.3 to 7.9 on the Richter scale. It wreaked the most damage in Canada, but in Boston and Portland it toppled chimneys, tossed pewter off ...

Jun 1, 2023 · 1663 CE earthquake is largest to occur in CKSZ over the past roughly 10 ka. This paper examines the distribution, stratigraphy and chronology of landslide deposits within the Gouffre Valley to provide a long-term context for the 1663 CE M 7.0–7.5 Charlevoix earthquake, Charlevoix-Kamouraska Seismic Zone (CKSZ), southern Quebec, Canada.

Jun 1, 2011 · This paper presents a new and comprehensive analysis of the magnitude of the 1663 Charlevoix, Quebec, earthquake. Based on a modified Mercalli intensity scale (MMI) of about VI from reports of damage to chimneys and a masonry wall in Roxbury and Boston, Massachusetts, the best estimate of the moment magnitude of this earthquake is M 7.3 to 7.9 ...
