| Goal of the report | This report descibes the earthquakes recorded by the seismograph stations of the Lower-Saint-Lawrence-Norther-Coast regions between January 1st and December 31, 2000. |
| Performance of the local network |
The Lower-Saint-Lawrence/North-Coast region
monitored by a local networkof 5 seismic stations: MNQ (Manicouagan), CNQ(Côte-Nord),
ICQ (Islets-Caribou) et SMQ (Sainte-Marguerite).
The local network is integrated into the Canadian National Seismographic Network. The uptime for these stations was very acceptable in 2000, ranking over 90%. Data from this station is continuously archived on optical disk Taking into account the distribution of stations in the Canadian network, any event with magnitude 2.0 or higher would be located. |
| Recorded earthquakes |
About 102 earthquake were recorded as shown in the map and described in the list.
Besides some isolated and low magnitude events, the large majority of them occurred inside the recognized seismic zone of the Low-Saint-Laurent. |
| Felt earthquakes | According to the reports of citizens and journalists, three earhquakes were felt locally. |
| Blasts | Many explosions related to work of the Sainte-Marguerite project (SM-C3) were detected. Their nature was confirmed by Hydro-Quebec with Bay-Comeau or their characteristic signatures. These explosions do not appear on the map and list above. |
| Induced earthquakes | Four events could have been induced by the variations of water level of the reserve of dam. Two of these earthquakes occurred under or near the tank from Manic-2 (January 23, mn February 1.9, and 19 2000, mn 1.5) and two close to the tank Sainte-Marguerite-3 (November 12, mn December 1.9 and 22, mn 1.4).
