Earthquakes create global-scale GPS errors

US: Twelve years of supersised earthquakes have contaminated GPS sites around the world, a new study finds. Except for spots in Australia, western Europe and the eastern tip of Canada, every GPS site on the ground underwent small but important shifts since 2000 because of big earthquakes, according to a study published in the Journal of Geophysical Research: Solid Earth.

The research confirms that great earthquakes, those bigger than magnitude 8.0, can have far-reaching effects on the Earth”s crust. And because GPS is critical for everything from calculating satellite orbits to sea level rise to earthquake hazards, scientists can”t ignore these tiny zigs and zags, the researchers conclude.
