Copyright ESA/IRAP/CNES/TU Delft/HTG/Planetary Visions Description ESA's GOCE satellite detected sound waves from the massive earthquake that hit Japan on 11 March 2011. At GOCE's orbital altitude, the concentration of air molecules is very low so weak sound waves coming up from the ground are strongly amplified. Variations in air density owing to the earthquake were measured by GOCE and combined with a numerical model to show the propagation of low frequency infrasound waves.

Measuring Earthquakes from Space

March 23, 2013By Meika JensenGIS Learning

Up until recently, seismometers have been a strictly Earth-bound devices, diligently tracking each and every change in the Earth’s surface due to earthquakes, volcanic eruptions, and tectonic plates shifting around. For the first time in the history of seismology, a device been able to capture the noise of vibrations caused […]

GIS continues to grow in several areas that will enable it to be an essential tool in designing the sustainable buildings of the future.

What is Geodesign?

September 30, 2011By Meika JensenGIS Learning

Recent progress with the use of technology to analyse data from various sorts to a very fine level of granularity has allowed planners to understand requirements as never before. The benefits that technology has brought to the planning world are considerable. A planning project can now use standard data sets […]

The Benefits of GIS

January 23, 2010By Meika JensenGIS Learning

GIS uses geospatial technology to create and manage information about location. In the strictest sense, the term describes any information system that integrates, stores, edits, analyzes, shares, and displays geographic information. GIS programs are resources that allow users to create entertaining issues (user created searches), evaluate spatial details, modify information, maps, […]
