Over the last decade, faster and more accurate GPS devices have allowed scientists to illuminate how the ground moves during big earthquakes. GPS has led to better warning systems for natural disasters such as flash floods and volcanic eruptions. And researchers have even MacGyvered some GPS receivers into acting as snow sensors, tide gauges and other unexpected tools for measuring Earth.
“People thought I was crazy when I started talking about these applications,” says Kristine Larson, a geophysicist at the University of Colorado Boulder who has led many of the discoveries and wrote about them in the 2019 Annual Review of Earth and Planetary Sciences. “Well, it turned out we were able to do it.”
Here are some surprising things scientists have only recently realized they could do with GPS.
