Locate modern addresses on Earth 240 million years ago

Pangaea Addresses

Ian Webster built a tool to plot modern addresses on a map of the Earth from up to 750 million years ago. Just input an address and it’ll find where that spot of land was on the Earth at a given time. The tool defaults to a view from 240 million years ago, smack in the middle of the Pangaea supercontinent era, but you can select views from 750 million years ago right up to the present. Webster explained a bit about the project on Hacker News:

I built this by adapting GPlates (https://www.gplates.org), an academic project providing desktop software for geologists to investigate plate tectonic data. I’m amazed that geologists collected enough data to actually plot my home 750M years ago, so I thought you all would enjoy it too.

Even though plate tectonic models return precise results, you should consider the plots approximate (obviously we will never be able to prove correctness). In my tests I found that model results can vary significantly. I chose this particular model because it is widely cited and covers the greatest length of time.

The visualization is open source and Webster is working on integrating the plate techtonics and location data into that repo soon.
