Recent earthquakes in Connecticut:

CT quakes

 

We recorded the recent magnitude 3.1 quake in Connecticut very well on both our research and educational seismographs.
Above is an interesting comparison of the differences in quality of recording for our research seismograph vs. our educational seismograph (both in Devlin Hall, Boston College).
If you were watching the Devlin seismograph on the day of the quake, and saw a sharp spike at the time of the quake, that was the quake (see graphic above).  It looks that way because we are displaying the entire day on the screen. The record is expanded to show what was recorded during the time of that short spike.
