Charlevoix - Natural History

Natural History

The topography of this region was dramatically altered by a meteorite impact that occurred 350 million years ago creating the Charlevoix crater.

"The impact created the forty-mile-wide crater that is the heart of Quebec's Charlevoix region, ranging from just west of Baie-Saint-Paul to just east of La Malbaie. Today, the area inside the crater is home to 90 percent of Charlevoix residents and is a very pastoral setting by comparison to what it could have been."

This area was subsequently reshaped by glaciation.

There have been several major earthquakes in the region in recorded history:

  • on February 5, 1663, centred south of La Malbaie. See 1663 Charlevoix earthquake.
  • on December 6, 1791, centred near Baie-Saint-Paul
  • on October 17, 1860, centred under the Saint Lawrence River
  • on October 20, 1870, centred near Baie-Saint-Paul
  • on February 28, 1925, centred under the Saint Lawrence River. See 1925 Charlevoix-Kamouraska earthquake.

There were 8 earthquakes between magnitude 4 and 5 on the Richter scale between 1977 and 1997 in Charlevoix, with minimal damages.

Famous quotes containing the words natural and/or history:

    Natural knowledge, seeking to satisfy natural wants, has found the ideas which can alone still spiritual cravings. I say that natural knowledge, in desiring to ascertain the laws of comfort, has been driven to discover those of conduct, and to lay the foundations of a new morality.
    Thomas Henry Huxley (1825–95)

    The history of the genesis or the old mythology repeats itself in the experience of every child. He too is a demon or god thrown into a particular chaos, where he strives ever to lead things from disorder into order.
    Ralph Waldo Emerson (1803–1882)
