UNAVCO Response

GPS/GNSS Real-time Data Streams
No signals from this event were recorded by UNAVCO real-time streaming GPS/GNSS stations.

GPS/GNSS Data - Custom Downloads for Post Processing
UNAVCO is downloading high-rate 1-sps (1 Hz) data from the few PBO/NOTA GPS/GNSS stations near the epicenter of this event. In addition, 5-sps (5 Hz) data are being downloaded from available sites. Due to the remote locations and limited comms of these sites, data will take longer than usual to be acquired. A station map is shown in Figure 2; this map will be updated after data are acquired. When downloaded, these data are available from the UNAVCO high rate data ftp site.

GPS/GNSS Displacements
Coseismic offsets from this event, if any, will be estimated by the GAGE GPS Analysis Center Coordinator (ACC), Professor Tom Herring (MIT). Any observed offsets will be tabulated and published in an event (*.EVT) file available from the UNAVCO data products ftp site. As more data and final orbits become available, final offset solutions, as well as offsets estimated from Kalman filter time series analyses, will be generated. Final and Kalman filter offset files will be added to the event file at the event products ftp site.

Borehole Strainmeter Data
UNAVCO has produced a fully processed 1-sps borehole strainmeter (BSM) dataset spanning the time period of this event. This dataset can be downloaded from the UNAVCO borehole strainmeter event response page.
