Recommended NISAR GSLCs for Interferogram Notebook

[jwhite124]

I am about to start working on a notebook for ASF's NISAR Cookbook that produces an interferogram from two GSLCs. I'd like to pick an area that (1) shows interesting change and (2) is relatively simple to understand. Does anyone have any suggestions on where to look? Or know of an interesting (non drastic) event that would have been captured by the NISAR data that's currently available?

The two examples of large deformation that I know about in the February release are the December volcanic eruption in Ethiopia, and the ongoing deformation of the landslide on the south coast of Palos Verdes peninsula south west of Los Angeles. The volcanic eruption deformation is quite large so it is a clear signal.

On 12-day NISAR pairs, the Palos Verdes landslide complex moves slightly less than one fringe, so it is visible but not so dramatic. It is a well-known landslide complex.

I forgot, another example of surface deformation that is in the February release is the subsidence of Mexico City. It is somewhat slower than the Palos Verdes landslide complex, so it is less visible in a 12-day pair but more visible in longer intervals. This is well-known ongoing subsidence of the city due to compaction of the lake sediments that it was built on.
