Ground motion visualization animations display real accelerations that have been
measured at selected seismic stations across the state. The scale runs from 0 ug
to greater than 500 ug. A ug is 0.0001 % the acceleration of gravity.
While the exact details are very complex and dependant on the individual situation,
many humans can perceive motions greater than 1500 ug.
