The 1925 Charlevoix-Kamouraska earthquake was a major earthquake that struck the entire northeastern part of North America on February 2, 1925, reaching 6.2 on the moment magnitude scale.^[1]

This earthquake is one of the most powerful earthquakes of the 20th century.^[1] The main shock epicenter occurred in the area of Quebec City and Shawinigan and was felt as far south as Virginia, and as far west as Mississippi.^[2] It caused damage in three separate areas. The first had extreme damage constricted to a narrow belt 20 miles long on both shores of the Saint Lawrence River near the epicenter.^[3] In this area, damage at the villages of Baie-Saint-Paul, Saint-Urbain, Les Éboulements, Pointe-au-Pic, La Malbaie, Tadoussac and the other nearby villages of Ste-Anne-de-la-Pocatière, St-Pacôme, Rivière-Ouelle, Saint-Philippe, Saint-Denis, and Saint-Pascal on the south shore, was remaining mostly to the strength of the earthquake's irritation in some reasons by the deep grainy soil on which the destroyed buildings were built.^[3] The two other damaged areas were Quebec City and in the Trois-Rivières - Shawinigan regions where the destruction was worst, not so much to the strength of the earthquake, as to the uneven nature of the landscape.^[3] A total of 55 aftershocks were recorded, which lasted for weeks, ranging from magnitude 5 to 2.^[4] Over the years, several studies were published on the 1925 Charlevoix-Kamouraska earthquake, some as recently as 1999.^[1]
