Σεισμοτεκτόνικη μελετή των νήσων του Ανατολικού Αιγαίου.

Περίληψη

In the present study an examination of the seismotectonic features of eastern Aegean is made with the use of the accurately determined focal parameters of the earthquakes occurred. A description of the seismotectonic properties of the area is reported and information about the tectonic features and the formation of the study area are presented. Evidence of the strongest shocks and their macroseismic results are described from reports from historical times, and information for the focal mechanisms of them. In order to examine the seismotectonic properties of the study region, accurate focal parameters of the earthquakes occurred in the area are necessary. For this reason earthquake data were collected and with a procedure followed, travel time residuals were calculated for each station used, and relocation of them was done with the use of the HYPOINVERSE computer program. The results from the relocation of the earthquakes showed the spatial distribution of the seismicity of the area and they were compared with the results of other studies in order to examine the accuracy of them. Finally some study cases of earthquake sequences were made with the use of the HYPODD location program and the use of the static stress changes, to investigate the interaction between events in the study region.
