Recent research articles published in magazines Earthquake Science (EQS)) report on a new use of GNSS data in a seismological study conducted in northeastern Tibet, the highest region on Earth (>4500 meters above sea level).
The researchers report on the results of combining GNSS and seismic anisotropy data.
Key Point
- For the first time, Global Navigation Satellite System (GNSS) deformation data were collected and used simultaneously with seismic anisotropy data to determine regional distribution characteristics of surface and upper crustal deformation. We summarize the application of this technology in the northeastern Tibetan Plateau and its adjacent regions.
- Differences in deformation at the crustal surface and upper crust are analyzed to reveal differences in regional deformation mechanisms.
- Combining GNSS data and seismic anisotropy data can reveal differences in depth variation in regional crustal deformation.

GNSS data reveals surface deformation caused by seismic activity, and the authors report that “GNSS velocity fields reflect the kinematic signature of tectonic activity and directly reveal tectonic patterns.”
