so far we know that GPS is a tool to track the whereabouts and give directions or where a place is located or where a place was usually placed in the car. but different with this one GPS, GPS has been modified, combined with the accelerometer and barometer which can then be used to predict earthquakes and flash floods.
quoted from the MIT Technology Review, At the fall meeting of the American Geophysical Union in December , cientists from Scripps Institution of Oceanography ( SIO ) in San Diego , NASA's Jet Propulsion Laboratory ( JPL ) in Pasadena , and the National Oceanic and Atmospheric Administration ( NOAA ) they explained that the way they do is by piggybacking on existing networks that spread hundreds of GPS in Southern California . on some of these stations , initially diapasang to measure the movement of the tectonic boundary between the Pacific Plate and the North American Plate , the researchers have added other seismic and meteorological sensors that allow it to be able to monitor malicious activity in real time and even predict malicious activity before it occurs . The prototype system was tested this past July .
the amount of time it takes the signal from the satellite to the ground can be used to measure the moisture level of the troposphere . then the data is combined with the humidity and barometer thermometer which can then be used to increase accuracy in predicting rainfall and flash flooding .
to predict earthquakes the researchers added to the base station accelerometers , GPS sensors record changes while large land position , accelerometers take a small movement
Yehuda Bock , geodesist research and project lead at SIO , explaining that combines GPS and data suitable for estimating accelerometersangat big , fast , and other characteristics of earthquakes with magnitudes between 7 and 9 . In addition , Bock said , accelerometers take primary or P - wave , which can be used to predict the arrival of the secondary or S - wave that marks the beginning of the damage , violent shaking during an earthquake . and this information can be integrated into an early warning system .
