The Real-time Earthquake Analysis for Disaster Mitigation Network is a NASA-inspired research project that leverages the 600+ station real-time GPS super-network (Datasources) in Western North America to prototype an earthquake and tsunami early warning system using GNSS technology as well as GNSS/seismic integration (seismogeodesy). Primary participants include real-time UCSD's Scripps Institution of Oceanography, Central Washington University, Caltech's Jet Propulsion Laboratory, University of Washington and University of Oregon.
Currently, the primary projects include (1) development of a local tsunami warning system using GNSS and seismogeodetic data, in collaboration with NASA and NOAA’s Tsunami Warning Centers in Alaska and Hawaii – include hyperlink when available, (2) tsunami early warning system by GNSS ionosphere monitoring.
Upgrades of UNAVCO/PBO and SOPAC stations include deployment of SIO Geodetic Modules and MEMS accelerometer packages (GAPs – add hyperlink when available) at existing real-time GNSS stations in southern California and the San Francisco Bay Area (locations are available through the map interface).
In February 2018, the CSRC published a new geodetic datum for California called “CSRS Epoch 2017.50 (NAD83)” under a Caltrans contract to SIO/SOPAC. The new epoch-date coordinates will be transmitted with RTCM 3.0 data streams starting March 1, 2018.
