This page allows you to see ground vibrations by viewing seismic waveforms recorded at the stations of the Canadian National Seismograph Network. For examples of what various earthquake signals look like, see Interpreting Seismograms.

The clickable calendar-style entry form provides a number of seismogram display options: a network-hour showing all active stations in the Network; a station-day (24 hours) showing the selected Single Station; or near Realtime data from a list of available stations. Time periods for which selected seismograms are not available appear "greyed out" on the corresponding calendar entries.

Note that the form and the associated waveform plots use Coordinated Universal Time (UTC).
