For mapping the seismic activity tlie earthquake energy<br />releaseil per square degree per liundred years was determined, and tlie values<br />obtained were used for drawing isoenergetical lines. Two maps constructed<br />in this way for the periods 1710-1959 and 1841-1959 show clearly tliat the<br />earthquake activity in the Greek area is concentrated, for the most part, along<br />the large fault zone bordering the western and southern coasts of Greece.<br />It is believed tliat this fault zone marks the trend of a marginai geosyncline,<br />which is now in the course of development in the Eastern Mediterranean.<br />Tlie map of earthquake efflciency in Greece sliows clearly tliat the main<br />part of the earthquake energy released in the Greek area comes frolli two<br />well developed centres of higher seismic activity, located along the abovementioned<br />large fault zone.
