Objective
To process and interpret about 2000 km of multichannel marine seismic data, including signals received at land stations. Specific objectives are the evaluation of the performance of a new marine seismic source, interpretation of the crustal images in the Ionian and Aegean seas in relation to present-day tectonics, and comparison of the crustal signatures of the Aegean volcanic arc and Mt. Etna.
The close contact that was maintained between the partners throughout the project ensured that all the project's objectives were fully met. The signals from the new seismic source were found to be ten times stronger than signals from conventional methods. This produced a much clearer signature of the earth's crust, in which there was greater clarity to rock fractures and other geological phenomena. The identification of deep fault structures in the crust has important implications for predicting the occurrence of major earthquakes and volcanic activity. Also, the new seismic method does not generate high frequencies which are harmful to wildlife.
This work builds on and continues the work of the STREAMERS project (JOUG-CT90-0013) and other nationally funded seismic surveys in the Mediterranean and Aegean regions. This contract covers the processing of multiple coverage multichannel marine seismic data to common mid-point stack time sections. Interpretation will cover three separate areas: - Processing of the STREAMERS data from the Ionian sea.
- Processing of the STREAMERS data from the Aegean sea.
- Processing of ETNASEIS data (contract no. EV5V-CT92-0187) from around Sicily.
Each of these parts will be reported in a separate document. As half of the seismic profiles have been shot with a new design of seismic source which offers significant budgetary and logistical savings, the project will include an evaluation of the relative performance of this equipment and its more expensive conventional counterpart.
The purpose of the work is to provide input to models of crustal structure, fracture and fluid circulation properties and environmental hazards arising from the complex and active tectonics of the region.
