3D satellite, GPS data can cut post quake deaths
GPS and satellite data can be used in a real-time, coordinated effort to fully characterise a fault line within 24 hours of an earthquake, ensuring that aid is delivered faster and more accurately than ever before, new research shows. Researches created a 3D map of how the ground surface moved in response to the earthquake. The map was made without using traditional rapid response instruments such as seismometers which may not afford the same level of detail
New York: GPS and satellite data can be used in a real-time, coordinated effort to fully characterise a fault line within 24 hours of an earthquake, ensuring that aid is delivered faster and more accurately than ever before, new research shows. Researches created a 3D map of how the ground surface moved in response to the earthquake. The map was made without using traditional rapid response instruments such as seismometers which may not afford the same level of detail for similar events around the globe. The technique will be most useful in the developing world. On an international scale, it dramatically reduces the time between when an earthquake happens, when buildings start to fall down, and when aid starts to show up, the authors wrote.
