Satellite photos of New Zealand coastline before and after 7.8 earthquake

Monday’s massive earthquake lifted the seabed 1-2m around the coast.

You can even see the epic uplift from low resolution satellite photos. Surfers are wondering how their breaks will change. I’m wondering what happened to the sand castle I built in March.

The differences below look sliiiightly greater than they really are, because the post earthquake photo was taken at extremely low tide. I found it difficult to find satellite photos on cloudless days where the tides were exactly the same.

all photos from LandSat 8, easy to get on EarthExplorer. Each pixel in the photos is about 30m.
