GPS Satellites: Early Detection of Earthquakes Possible

Researchers have discovered that GPS measurements may be able to detect precursors to earthquakes several hours before the main event. By analyzing GPS data from stations near known earthquake locations, the researchers found that the ground's motion began to align with the expected motion in the final two hours before a quake. However, current technology is not sensitive enough to detect these precursors, and significant advancements would be needed to make earthquake prediction possible. The study provides evidence that earthquakes may have precursor elements and raises questions about the cause of certain motion cycles observed in GPS data.
