NASA Developing Natural Hazard Warning Systems

Scientists at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., and Scripps Institution of Oceanography at UC San Diego have enhanced existing GPS technologies to develop new systems for California and elsewhere to warn of hazards from earthquakes, tsunamis and extreme weather events.

The technology was demonstrated in July by forecasters at NOAA National Weather Service offices in Oxnard, Calif., and San Diego. They used it to track a summer monsoon rain event affecting Southern California and issue more accurate and timely flash flood warnings. The system uses real-time information from GPS stations upgraded with small, inexpensive seismic and meteorological sensors. (more…)

PASADENA, Calif. – The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States. Results from the new Real-time Earthquake Analysis for Disaster (READI) Mitigation Network soon could be used to assist prompt disaster response and more accurate tsunami warnings.

The new research network builds on decades of technology development supported by the National Science Foundation, the Department of Defense, NASA and the U.S. Geological Survey (USGS). The network uses real-time GPS measurements from nearly 500 stations throughout California, Oregon and Washington. When a large earthquake is detected, GPS data are used to automatically calculate its vital characteristics, including location, magnitude and details about the fault rupture. (more…)
