The corrected accelration time histories of Northern Canada earthquakes (north of 52°N)and their pseudo spectra (PSA) are presented here. The catalogue of earthquakes covers the time histories of earthquakes recorded at CNSN and POLARIS stations after 1994.

The information of all records, including the values of PSA ordinates for 28 frequencies from 0.1Hz to 50Hz, PGAs and PGVs as well as information of stations and earthquakes, can be found here.

The database contains one zip file for each event. Time history information of one channel of data is stored in a file and its response spectrum is stored in another file. The event zip file contains time history and PSA files of all channels that recorded the event and considered useful for being kept in database. Please click here to go to the database page.
