Sentinel-1 provides support in Taiwan's earthquake
22 February 2018
The Sentinel-1 satellites of Europe's Copernicus Programme are being used to quantify the surface deformation of the disaster area around the Hualien earthquake.
On 06 February 2018, an earthquake of magnitude 6.0 on the Richter magnitude scale hit Taiwan. The epicentre was on the coastline near Hualien, which was the most severely affected area, with a maximum shaking intensity of 7.
The earthquake formed the largest of a sequence of events that affected the area over a period of days, with 11 foreshocks of magnitude 4.6 and greater, starting on 03 February. The 06 February earthquake was a result of oblique-slip faulting.
The Centre for Space and Remote Sensing Research (CSRSR) in Taiwan accessed Sentinel-1 data after the earthquake struck. Researchers there have been downloading Sentinel-1A data from data hubs since 2014, for multidisciplinary research and application. The additional acquisitions obtained largely inspired local researchers, such as Dr Jiun-Yee Yen, and colleagues Chih-Heng Lu and Chun-Ching Wang at the Eastern Taiwan Earthquake Center (ETEC), who processed the Sentinel-1A and -B data, producing deformation maps.
