1935 Timiskaming earthquake

From Wikipedia, the free encyclopedia

The 1935 Timiskaming Earthquake was a magnitude 6.2 earthquake that occurred on November 1, 1935 in the Abitibi-Témiscamingue region of Quebec.

The earthquake had its epicenter on a thrust fault in the Ottawa-Bonnechere Graben, approximately 10 kilometres east of Témiscaming, and occurred at 1:03 a.m. ET.

Although the most significant damage connected to the earthquake was to chimneys, both in the immediate area and as far south as North Bay and Mattawa, a railroad embankment near Parent, 300 km away, also collapsed as a result of the earthquake. Researcher E. A. Hodgson later concluded that the embankment slide was already imminent, and was merely hastened by the earthquake vibrations. Some rockfalls and structural cracks were also reported, although there were few major structural collapses aside from the Parent embankment. The relative lack of major damage has been attributed primarily to the sparseness of the area's population.

The earthquake was felt over a wide swath of North America, extending west to Fort William, east to Fredericton, north to James Bay and south as far as Kentucky and West Virginia. Occasional aftershocks were also reported for several months following the earthquake.

A magnitude 5.2 earthquake on January 1, 2000 had its epicentre at Lac-Kipawa, very near the epicentre of the 1935 quake.
