Another earthquake spot is on the north shore of the St. Lawrence River, most interestingly just in a large meteorite impact structure ( "astrobleme") called Charlevoix.
A comprehensive comparative analysis with other complex meteorite impact structures demonstrated that it is the oldest, the largest and the only example on earth providing a full geological profile of an astrobleme below the crater floor, thereby enabling research into the genesis and development of an astrobleme immediately post impact.
Only one astrobleme in Europe fit the description, a crater called the Ries that lay some 300 kilometers to the east, on the northern shore of the Danube River.
The structure called the Ries (or Rieskessel) is the subject of some controversy-one school of thought accepting it as an astrobleme, while another holds it to be the result of a cryptovolcanic explosion that brought to the surface "meteoritelike" materials.
The word 'astrobleme' comes from the Greek 'astron' ("star"), plus 'bleme' "throw of a missile; wound caused by a missile".
