ΣΕΙΣΜΙΚΗ ΤΟΜΟΓΡΑΦΙΑ "ΠΡΟΣΔΙΟΡΙΣΜΟΣ ΖΩΝΩΝ ΤΑΧΥΤΗΤΑΣ ΣΤΟΝ ΕΥΡΥΤΕΡΟ ΕΛΛΗΝΙΚΟ ΧΩΡΟ"

3-DIMENSIONAL VELOCITY STRUCTURE BENEATH GREECE AND SURRONDING REGIONS IS DETERMINED USING THE METHOD PROPOSED BY AKI AND LEE. THE DATA USED ARE ARRIVAL TIMESOF P-WAVES FROM 166 EARTHQUAKES WHICH OCCURRED SINCE 1972 TO 1986 AND RECORDEDAT 62 STATIONS IN THE AREA INCLUDED BETWEEN 33.0 N - 43.0 N AND 18.0 E - 30.6 E. THE EARTH'S CRUST AND UPPER MANTLE BENEATH THE INVESTIGATED REGION IS DIVIDED INTO 10X10 RECTANGULAR BLOCKS OF 1 SIZE. FOUR LAYERS OF 40KM THICKNESS WERE USED. BY INVERSION OF THE DATA, THREE MAIN VELOCITY ZONES WERE DETERMINED. I) A HIGH VELOCITY ZONE AT THE MARGIN OF EUROPEAN PLATE. II) A HIGH VELOCITY ZONE WHICH COINCIDE WITH THE AFRICAN ILAH AND III) A LOW VELOCITY ZONE AT AEGEAN SEA, WHERE LARGE SCALE EXTENSION AND VOLCANIC ACTIVITY ARE PREDOMINANT.
