The BRS was very rung up this morning so I went to investigate. It looks like the damper may have caused the BRS to ring up.
People were at End X yesterday but left around 1230 pst, where as the BRS didnt start to dramatically ring up till around 1900 pst. The damper seemed to be on before the large amplitudes seen on both the INMON and the DRIFTMON. Siesmometers aren't showing any signs of an earthquake within the past 24 hours, so that seems to be be out.
I went to EX to turn OFF the damper by uncommenting the line of code, and adjust the damper masses (about 75 degrees out of position). I left the damper OFF to allow the BRS to ring down on its own like we have done previousily.
Screenshots attached: 1st - A 4.5 hour view around the event. 2nd - 24 hour trend. In the 2nd, you can see when people were at EX and the damper seemed to relax the signals back down to normal where they stayed for a little over 4 hours before everything picked up again.
