Abstract:
We have analyzed a set of ERS-2 images to investigate centimetric
surface deformations within the city of Paris (France) using the radar
interferometry technique. We show that a large scale uplift phenomenon
occurred during the summer 1998 south of the Saint-Lazare railway
station (maximum amplitude of 1.3 cm +/- 0.3 cm). This area corresponds
to an important underground working site, which required to lower the
piezometric level during 1995 and 1997. The uplift correlates in time
with the increase of the underground water level at the end of the
construction work. The amplitude of the uplift corresponds to the
amplitude of a subsidence which was previously observed in the same
area, suggesting that the deformation mechanism is elastic and not
simply due to compaction.
