Reply #8: You and computer could only stay still in a building moving [View All]

3 feet in one direction and then the other if you and the computer were suspended in mid-air. Otherwise the computer certainly moved in space, even if it did not move relative to the desk.
If the program is in there to see if computer fell the measurement would likely begin with the sudden movement before it falls to get more information on the fall. So even if it shifts through space and doesn't fall that move would provide the earthquake info
