4.1.3 Where shrinking-swelling occur in France

Hence, high damage related to shrinking and swelling has been recorded. Since 1989, it is more than 5 000 communes for 75 departments, which were affected par the shrinking-swelling. This phenomenon is largely distributed. However, certain areas are more particularly affected in close relation with the geological nature of the ground. It is the case in particular of the plain of Flandres, the southern part of the Basin of Paris, the graben of Limagne, the area of Apt and especially of the whole of the molassic slopes of South-west, between Agen and Toulouse and many others to a somewhat lesser extent.

In the figure we could see a number of times that a commune was recognized in a ‘state of natural disaster’ (following the law of 13 July 1982) with respect to shrinking-swelling until August 15, 2006 (from http://www.argiles.fr/)
