Improving Local Tsunami Warnings by Combining Geodetic and Seismic Observations

Combining geodetic and seismic observations can reduce the amount of time needed to assess the tsunami intensity generated by a large magnitude thrust fault earthquake along a subduction zone. Through retrospective analysis of four tsunamigenic large earthquakes in Japan and Chile, the tsunami potential at the local coast was estimated within less than 2 minutes.

Testing Earthquake Early Warning Using Geodetic Data in the Pacific Northwest

The addition of geodetic data into the Pacific Northwest Seismic Network earthquake early warning system shows important enhancement to the warning system. Tests show the Geodetic First Approximation of Size and Time (G-FAST) could determine the characteristics of the 2001 Mw 6.8 Nisqually earthquake with sufficient robustness to warn communities at risk.

Seismogeodesy for Rapid Earthquake Response

Combining geodetic and seismic measurements for the moderate 2014 Mw 6.1 Napa, California earthquake shows that rapid earthquake assessment is effective, so in a future real-time implementation, early responders will have more information to know where to concentrate their efforts to mitigate losses.

Quality Assessment: A new technique to assess and monitor long-term quality of GPS data

Before becoming a professor of physics at the University of Nevada Reno (UNR), Dr. Friedwardt Winterberg published a paper in 1955 that proposed a direct test to investigate one of the most important theories of modern physics: general relativity.

Researchers working towards automated generation of life-saving imagery following an earthquake using UNAVCO datasets

Geodetic imaging such as InSAR combined with GPS has provided the means to view the surface deformation caused by earthquakes at a high level of detail, but currently these images require up to several days to be created by an expert.

UNAVCO facilitates access to inter-disciplinary datasets, and supports the development of a Geodesy Community Workbench

UNAVCO has helped collect and distribute huge amounts of GPS data throughout the world, on the order of several pedabytes, providing unprecedented access to free high-quality scientific data. The next step may be the development of a Geodesy Community Workbench, which would provide a unified framework for analyzing and interpreting GPS data, according to researchers at the University of Nevada in Reno.
