We are currently working
with other groups in Europe to bring over very new technologies that are not
currently being utilized in North America.
A group from Italy (LiSALAB) has developed a ground based InSAR system
(left) that can do repeat short interval scans of slopes up to a three
kilometers away to generate deformation maps at a higher resolution and
frequency than can be obtained from spaceborne InSAR. Also, as this technique can be used at
night and in fog, it has distinct advantages over laser techniques. This technique has been used on volcanoes
in Italy and the application shown is for a rock slide on a fjord in Western
Norway. The reflector shown on the
right is for another ground based radar system used at another site in
Western Norway artificial targets are used to monitor point source movements
on a large rock slide.
