BCH Dam Safety: Historical Ground Motion Recordings


The purpose of this project is to compile ground-motion recordings from induced earthquakes in the Western Canada Sedimentary Basin (northeast British Columbia and western Alberta). This project includes three steps. In the first step, a catalog of earthquakes in the region is compiled from various sources including Natural Resources Canada, Alberta Energy Regulator, and published papers. In the second step, waveforms are gathered for each earthquake in the catalog. The third step includes waveform processing and compilation of aground motion table. The table contains earthquake parameters (date and time, location, local and moment magnitudes, and depth) along with ground motion parameters in terms of peak ground acceleration, peak ground velocity, peak ground displacement, and pseudo-response spectral acceleration at selected periods. Moreover, the database includes strong motion duration (bracketed and significant duration) and Vs30 for each station.
