Quick quake calcs: GNSS data speed up assessment

POSTED ON JULY 6, 2023 BY TEMBLOR
Global satellite navigation systems (GNSS) can be used to help quickly characterize damaging earthquakes when seismic sensors aren’t available, according to new research. GNSS data especially help in areas where broadband seismometers are sparse.

Earthquakes generate body waves that travel through Earth. They can be used to study Earth’s internal structure, just like a CT scan that images your body. These seismic waves also reveal properties of the event, such as location, depth, ground motion and magnitude. These parameters are crucial for quickly characterizing an earthquake, especially if the event has the potential to produce damaging shaking, tsunamis or other associated hazards, says Revathy Parameswaran, a Research Associate at the University of Alaska Fairbanks and the lead author of a new study.
