| Goal of the report |
This report descibes the earthquakes recorded by the seismograph stations of the
Western Quebec region between January 1st and December 31, 1998.
|
| Performance of the local network |
The Western Quebec Seismic Zone
is monitored by 9 seismic stations:
MNT (Montréal, Québec),
TRQ (Mont-Tremblant, Québec), WBO (Williamsburg, Ontario),
GAC (Glen Almond, Québec), OTT (Ottawa, Ontario),
GRQ (Grand-Remous, Québec), CRLO (Chalk River, Ontario),
SADO (Sadowa, Ontario) and EEO (Eldee, Ontario)
These stations belong to the
Canadian National Seismograph Network.
The uptime for these stations was very acceptable in 1998, ranking over 90%. One must note however that the clock of GAC is not synchronized with the remainder of the network. Data from this station is continuously archived on optical disk Taking into account the distribution of local network in the Canadian network, any event with magnitude 2.0 or higher would be located. |
