    SUMMARY: The European Space Agency's Envisat Earth observation satellite is so sensitive it can track changes on the surface of our planet that move at the pace your fingernails grow. One of Envisat's tasks as it orbits the Earth every 100 minutes is to make a precise map of the seismic areas that make up 15% of the planet's surface. At the end of its five year mission, the spacecraft will have provided details about how these seismic areas have changed over time. By comparing these changes to the locations of earthquakes around the world, scientists should get an insight into regions that could be due for a shakeup.

    This is an interesting story, Fraser.

    Public support for ESA and NASA may improve if the Envisat satellite successfully obtains information on seismic areas - information that might be useful in forecasting earthquakes.

    With kind regards,

    Very cool info! It's only a matter of time before a big one hits out west. It's been along time, and way over due!

    It could be useful to track the movement of vehicles (military) too I suspect.
