1510 -1540 hrs. local -> Unloaded pump from trailer and moved into the Mechanical Room using the smaller of the two roll-up doors (not the Large Equipment Access, LEA, door).  Likely created a measurable seismic signal at 1518 hrs. local and again 10 -15 minutes later as pump rolled over trailer-to-concrete transition and building doorway threshold.
