Paleoearthquake features as indicators of potential earthquake activities in the Karameh dam site

Prehistorical earthquake induced features, such as faults, folds, fissures, and slumps have been discovered during the Karameh dam construction. The d am is located close to the plate tectonics boundary formed by the active Jo rdan Valley Fault. Of most importance are those known as the fold-type defo rmations "decollement type of structure" which are well preserved in the la minated Lisan formations. These features show that historical moderate to s trongly sized earthquake activities are likely to have been originated in t he vicinity of the dam site. Such features may well provide valuable inform ation for identification of areas of highly strong earthquake regions.
