InSAR in Wenchuan - China

Funky 'Seismic' Pattern

InSAR is the hottest tool to use from space - look how totally hippie the Wenchuan earthquake looks like using interferometry.

Using InSAR and GPS data, scientists are able to measure and monitor where and how stress changes in the crust as well as how any associated deformation is distributed.

We are definitely going to see more of these kind of maps! :-)

And oh, yeah. I dedicated an episode of A Green Space - A Green Earth to natural hazards. There you can see equivalent maps of L'Aquila after the earthquake this April. It has absolutely nothing to do with G8 in case you wonder...:-)
