Abstract: Displacement waveforms derived from Global Navigation Satellite System (GNSS) data have become more commonly used by seismologists in the last 15 years. Unlike strong-motion accelerometer recordings that are affected by baseline offsets during very strong shaking, GNSS data record displacement with fidelity down to 0 Hz. Unfortunately, fully processed GNSS waveform data is still scarce due to limited public availability and the highly technical nature of GNSS processing. In an effort to further the use and adoption of high-rate GNSS for earthquake seismology, ground-motion studies, and structural monitoring applications, we describe and make available a database of fully curated high-rate GNSS displacement waveforms for significant earthquakes. We include data from high-rate GNSS networks at near-source to regional distances (1–1000 km) for 29 earthquakes between Mw6.0 and 9.0 worldwide. As a demonstration of the utility of this data-set we model the magnitude scaling properties of peak ground displacements (PGD) for these events. In addition to tripling the number of earthquakes used in previous PGD-scaling studies, the number of data points over a range of distances and magnitudes is dramatically increased. The data are made available as a compressed archive with the manuscript.
