A preliminary map for co-seismic landslides of the New Zealand M7.8 earthquake (13 November 2016) was compiled using available satellite images.
Landslides were mapped using Sentinel-2 satellite images from Copernicus, European Space Agency, dated 15 November 2016. Images were compared with previous last available image without cloud cover (13 September and 26 October). Areas covered by cloud are omitted and shown on map. 1092 landslide sites are shown. Due to the preliminary nature of the map, a small number of landslides could have been mis-identified due to insufficient resolution of the images or for other reasons. Authors believe the spatial coverage is sufficient for available data and restrictions.
High resolution map files and a .kml are available here https://zenodo.org/record/167130
More material about the earthquake environmental effects will be available soon.
