Earthquake in Taiwan: Ground Displacement of More Than 10 cm


On February 5, an earthquake with a magnitude of 6.4 hit southern Taiwan, resulting, according to the latest report, in 116 deaths and in the destruction or damage of more than 100 buildings in the city of Tainan.

Using radar interferometry, a technique used to target displacements to the nearest centimetre, Effigis’ Earth Observation Team tried to determine whether the impact of the earthquake could be measured.

The result: The differential interferogram obtained from SENTINEL 1A (ESA) satellite data from January 9 to February 14, 2016, indicated that there were ground displacements of more than 10 cm following the event.
