Something similar was experimented with where I live (western Sweden) to see if the technology is usable to determine the stability of soil layers against land slides. The area around the local river - Göta Älv - is known to be prone to landslides so it was deemed to be a good test subject. A helicopter carrying something which was best described as an enormous chicken run on a long line criss-crossed the area mapping it with what I assume was ground-penetrating radar. The results [1] show our farm to lie on an extremely landslide-prone part of the river valley and I know there have been landslides here in the 60's so there is something to this method. The subsoil consists of silt (the fraction over clay) on top of bedrock, as long as the water content stays below a certain percentage it has quite a high bearing capacity but once it gets over that it easily liquifies.
