How much Everest moved

Jack Linshi has a Time article about the Nepali quake:

The earthquake that struck Nepal was powerful enough to move a mountain, Chinese authorities said.
Mount Everest (photo) shifted three centimeters southwest after the quake on 25 April 2015, according to data from a satellite set up in 2005 by China’s National Administration of Surveying, Mapping and Geoinformation, its state-run news organization Xinhua reports. That’s a significant movement for Everest, which the agency said has moved only four centimeters annually on average between 2005 and 2015, due to crustal movements.
Authorities said the geophysical impact of the devastating quake, which left nearly nine thousand people dead, did not change the height of the world’s tallest peak.
