  1. That is the coolest image, and I wanted to make an astro-interferometer. If only I thought to look down instead of up. Duh

  3. Those are interference lines. They combine two scans, one before the earthquake and one after. I sort of think of them like contour lines. Where you see a lot of them, that's where there has been permanent displacement.
