The GPS data is from JPL and NASA and the attached caption reads: The displacement is both horizontal and vertical. The displacement in space ranges from just a fraction of a meter to more than 4 meters (24 ft).
Imagine the amount of energy necessary to shove tens of thousands of square kilometers of landscape a meter or more in a matter of seconds!
Cool. (Though 4 meters is only about 13 feet.)
ReplyDeleteWell tectonic plates usually only move aobut 70mm a year average. So 4m = 4000mm... Japan moved ALOT.
ReplyDeleteYeah but still, 24 feet is nearly 8 metres. Do NASA work on a 100 % error is close enough?
