More Insar on the Chinese Quake


First the Italian earthquake, and now this. The Insar technique is proving to be very powerful in mapping out the post-quake deformation field.

That is the coolest image, and I wanted to make an astro-interferometer. If only I thought to look down instead of up. Duh
Peter, de the (still) wiggling wires, near Peterborough. How prescient of them to name it before me.

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.
