The National Earthquake DataBase (NEDB) comprises a number
of separate databases that together act as the national repository for all
raw seismograph data, measurements, and derived parameters arising from the
Canadian National Seismograph Network (CNSN), the Yellowknife Seismological
Array (YKA), previous regional telemetered networks in
eastern and western Canada (ECTN, WCTN), local telemetered networks (CLTN,
SLTN), the Regional Analogue Network, and the former Standard Seismograph Network
(CSN). It supports the efforts
of Earthquakes Canada in Canadian seismicity monitoring,
global seismic monitoring, verification of the Comprehensive nuclear Test Ban
Treaty, and international data exchange. It also supports the
Nuclear
Explosion Monitoring project.
The Parameters database contains available information for all
Canadian earthquakes since the 16th century, including epicentral
solutions, phase arrival measurements and comments, and (for modern events) an index to
corresponding digital waveform data stored in the National Waveform Archive.
The Stations database contains seismograph station-related data. This
includes stations of
cooperating agencies/networks such as POLARIS, SOSN, and NONT.
