The event occured within the Network of the Americas (NOTA) footprint. NOTA is a core component of the NSF Geodetic Facility for the Advancement of Geoscience (GAGE), operated by UNAVCO.
NOTA GPS/GNSS Real Time Data Solutions
11 GPS/GNSS stations within 300 km of the epicenter were operating in real-time during the event, i.e., they were continuously streaming high rate (1-sps / 1 Hz) data to UNAVCO (Figure 1). Typical latencies for real-time stations, the time lapse between and observation being recorded on the receiver and it arriving in Boulder are less than 1 second.
GAGE GPS/GNSS Displacement Estimates
Coseismic offsets were not estimated for this event.
