Description

A 7.8-magnitude earthquake struck New Zealand’s South Island near the town of Kaikoura on 14 November 2016. Sentinel-1 radar data from before (3 November 2016) and after (15 November 2016) the quake were combined to create this interferogram (contours are 2.8 cm of ground motion). The results shows that the quake caused the ground to uplift 8–10 m and offset features like roads that crossed the fault by up to 12 m. This caused large landslides and triggered a tsunami.
