Last Saturday, on 17th June, a landslide in Greenland caused a tidal wave, killing four people and injuring nine in the community of Nuugaatsiaq. Two other communities, Igdlorssuit and Viaqornat, were apparently affected. Read more about it on the Landslide Blog.

We thought it would be interesting to see the area in Google Earth using Sentinel-2 imagery. We downloaded the Sentinel-2 image from 19th June, 2017 and imported it into Google Earth:


The relative positions of the landslide and Nuugaatsiaq.Copernicus Sentinel data, 2017.

The distance between the landslide and the village of Nuugaatsiaq is about 30 km. Igdlorssuit is about 60km from the landslide site and Viaqornat just over 100 km.

A Landslide in California with Planet Imagery

We love Landsat and Sentinel-2 imagery for their easy accessibility and global coverage, but they are rather low resolution at 10 m per pixel for Sentinel-2 and 15 m per pixel for Landsat. Commercial satellite imaging company Planet, now covers the globe with greater regularity and higher resolution (typically about 3 m per pixel) and for the US state of California, releases the imagery under creative commons licence within a couple of weeks of capture. We recently came across a large landslide that occurred along the Californian coast in an area known as Big Sur.

We were able to find it in Planet’s tool ‘Planet Explorer’ for browsing their imagery. You need to sign up to view daily imagery, but signup is easy and free.

Once you have signed up you can try going here to see the location in Planet Explorer. Try comparing before and after images with the built in ‘compare’ feature.
