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

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 […]
