Scientific work on the 1925 Charlevoix-Kamouraska earthquake
Dr. Ernest A. Hodgson was the Dominion Obervatory seismologist who studied this earthquake. During 1925 and 1926, he made numerous field trips with his still camera in the areas most affected by the earthquake. He gathered numerous scientific data and first hand accounts.
In addition, he studied the recorded seismograms in order to locate the epicentre of the main shock. In fact, this earthquake was recorded by several canadian seismographs. The history of seismographs in Canada had started towards the end of the XIXth century.
