National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

The Seismic Activity in the Cyprus Area.

Publication Date	1965
Personal Author	Galanopoulos, A. G.; Delibasis, N. D.

Abstract	Cyprus has two dominate topographic features, the Kyrenia range in the north and the Troodos Mountain in the south. There is evidence that the summit of Troodos, an igneous massif, has been elevated by more than 3.000 meters since Cretaceous time while the rest of the island has risen only some 700 meters, indicating isostatic adjustment to the underthrusting of the Eurasian hinterland by the African foreland. Cyprus and the adjacent sea areas are covered by one of the largest positive gravity anomalies found in the eastern Mediterranean. This large positive anomaly is superimposed on a regional negative anomaly. The earthquakes history of Cyprus shows only 15 severe earthquakes with damaging effect on the island. Two of these were accompanied by tsunamis strong enough to cause destruction on the southern coast. During the period 1911-1963 there are records of 18 earthquakes with epicenters within a distance of 100 km from the nearest coast of Cyprus. Six of these had a magnitude of 5,8 to 6,5 while the rest ranged between 4,75 and 5,75. The fact that all but one of the 18 occurred in or near the zone of underthrusting suggests that the earthquake activity is closely related to the evolution and the deep-seated structure of this zone.
