From EARTH Magazine -- Global Positioning System (GPS) technology was conceived in the 1960s to provide precise time and location data to the U.S. military, but it was soon embraced by geodesists and earth scientists. The first major test of GPS as a seismic tool occurred on Oct. 17, 1989, when the Loma Prieta earthquake struck San Francisco just as the third game of the World Series was about to begin at Candlestick Park. The quake killed 63 people, injured several thousand and caused an estimated $6 billion in damage.
By Alex H. Kasprak -- Flying over 1300 kilometers above Earth, the Jason 2 satellite knows its distance from the ocean down to a matter of centimeters, allowing for the creation of detailed maps of the ocean’s surface. This information is invaluable to oceanographers and climate scientists. By understanding the ocean’s complex topography—its barely perceptible hills and troughs—these scientists can monitor the pace of sea level rise, unravel the intricacies of ocean currents, and project the effects of future climate change.
From EarthScope - Let your students play this game to learn how GPS is used to monitor volcanoes.
