Big earthquake, suspensions and ISIs tripped, damped and isolated

ops overvoew screenshot attached.  I untripped things but will not try locking tonight. 

While untripping suspensions I noticed that oddly IM2 watchdog rms monitors were just below the trip threshold, while the other IMs were 2-3 orders of magnitude smaller. The second screen shot shows this curious behavoir.  What about IM2 undamped is so different from the other IMs?
