| Abstract | The 20 October 1870 magnitude 6.6 Charlevoix Earthquake occurred at around 11:30am local time. The main shock was felt from Nova Scotia to the east to Sault Ste. Marie to the west and as far south as
Cincinnati, Ohio, almost 1500 km from the epicenter. Newspapers in Quebec City reported the extensive damage caused in Charlevoix by this earthquake. Based on these accounts, we know that the earthquake was sufficiently powerful to cause a few
landslides and soil liquefaction in the epicentral region. Damage was reported to many houses, including complete destruction of some dwellings, in Baie-Saint-Paul, Saint-Urbain, Ile aux Coudres and Les Éboulements. It is one of five known magnitude
6-7 earthquakes that have occurred in the Charlevoix Seismic Zone between 1663 and present. This Open File Report presents the macroseismic information and its ratings on the Modified Mercalli Scale for a total of 192 locations in Canada and the
United States. For each locality, the felt information is rated on the Modified Mercalli intensity (MMI) scale and tabulated in a Microsoft Excel sheet. The text of many of the newspaper accounts were copied and when possible, the newspaper clipping
was scanned. The Open File also provides a GoogleEarth kmz file that allows the felt information reports to be viewed in a spatial tool. |
| Summary | (Plain Language Summary, not published)
The 20 October 1870 magnitude 6.6 Charlevoix Earthquake caused damage near the piecntre and in the surrounding regions and was felt almost 1500 km from
the epicenter. This Open File Report presents the macroseismic information and its ratings on the Modified Mercalli Scale for a total of 192 locations in Canada and the United States. |
