Deformation Examples (cont'd)

Following are more case examples of deformation - hydro dams failure;

Rempen (1924); Gleneau (1932); Stava (1985) - all in Europe; San Fransisco (1928) and Teton (1976).

Cases of Stava, San Fransisco & Teton lead to the establishment of standards for deformation survey since 1920s.

Another case of deformation which was highlighted most is Turtle Mountain Alberta. Seventy people perished and the deformation was caused by geological structure and excessive coal mining.
