The Real-time Earthquake Analysis for Disaster Mitigation Network is a research project
that leverages the 550+ station real-time GPS supernetwork in Western North America
to prototype an accurate and timely earthquake and tsunami early warning system using
GPS (GNSS) technology as well as GPS/seismic integration (seismogeodesy).
NASA funds real-time GPS projects at UCSD's Scripps Institution of Oceanography,
Central Washington University, Caltech's Jet Propulsion Laboratory, and
University of Nevada Reno. NSF's EarthScope project and Earth Sciences
Infrastructure and Facilities fund seismogeodetic upgrades of GPS stations by
SIO and UNAVCO/PBO.
Upgrades of PBO and SCIGN/SIO stations include deployment of SIO Geodetic Modules
and MEMS accelerometer packages at existing real-time GPS stations in southern
California (locations are available through the map interface).
SOPAC computes real-time GPS satellite clocks and fractional-cycle biases for
use in precise point positioning with ambiguity resolution using real-time data
from GPS stations in North America
(outside the zone of active tectonic deformation in the Western U.S. and British Columbia).
READI Working Group
The project is overseen by the READI working group, and
includes data providers and users.
