The main earthquake event, Mw=7,8, occurred just after midnight, on Monday 13/11/2016, near the coastal community of Kaikoura-New Zealand, 93 kilometers NE of the city of Christchurch. A series of powerful aftershocks jolted New Zealand's South Island, triggering a tsunami and sending aftershocks across the country with at least two, officially reported, casualties. Shortly after the earthquake, four successive ascending Sentinel-1 Synthetic Aperture Radar images were acquired, two before (3/11/2016) the devastating earthquake and two after (15/11/2016).
