The contributions published in this volume are the re- sults of the NATO Advanced Research Workshop "Improvement of Joint Interpretation of Geophysical and Geological Data", which took place in Gradisca d'Isonzo in October 1987 and February 1988. Modern computer techniques were applied for geoscien- tific studies in a new dimension. 45 scientists from 7 Euro- pean countries, Canada and the united states of America par- ticipated in the workshop. Interactive discussions and modeling improved the understanding of the very complex structure of the investigated area. We thank all contributors, but especially those pub- lishing in this volume, for their active participation to ensure the success of the meetings. Not to forget to mention the groups of assistants from the Istituto di Minere e Geo- fisica Applicata of the University of Trieste and from the Institute of Geophysics of the Freie Universitat Berlin. Many thanks for their help around the clock. However, a major prerequisite for this success was given by the hospitality of the international Centre for Applied Sciences (ICAS) in the wonderful restored ancient pallazzi Torriani and Pretuna of the town of Gradisca d'Isonzo.Thus, we are thankful to the president of ICAS, Dr. H.R. Dahlafi, and to the town of Gradisca d'Isonzo, especially to the mayor, Signore Travan. The studies carried out in Gradisca d'Isonzo had been supported by a grant of the NATO Scientific Affairs Division and we express our thanks to Dr. L. da Cunha as a steady partner in the background.

The determination of crustal structure by means of explo­ sion seismology has been one of the major objectives of the European Seismological Commission (ESC) over the past twenty-five years. It was decided some time ago to publish the results of regional crustal investigations in Europe in a series of monographs. This publication entitled "Ex­ plosion Seismology in Central Europe - Data and Results" is Volume 1 in a sequence of publications dealing with the crustal structure in Europe. The European seismologists are indebted to the German Geo­ physical Society (Deutsche Geophysikalische Gesellschaft) for taking the initiative to publish this book. Thanks are due to the German Research Society (Deutsche Forschungs­ gemeinschaft) for providing generous financial support of the field measurements and data evaluation. It is hoped that this publication will stimulate a continuation of in­ vestigations of the earth's lithosphere in order to eluci­ date the details which are still not fully understood.
