Abstract The European Marine Observation and Data Network (EMODnet) Project provides freely available data on European seas. The main purpose of EMODnet is to overcome the fragmentation and dishomogeneity of the available data, providing access to a harmonized and interoperable database. The EMODnet Geology Lot includes information at multiple scales on the seabed and its substrate ( http://www.emodnet-geology.eu/ ). The dataset on ‘Geological events and probabilities’ collects information on landslides, earthquakes, volcanic structures, active tectonics, tsunamis and fluid emissions. The Geological Survey of Italy, which coordinates the collation of ‘Geological events and probabilities’ data, provided guidelines to compile layers complemented by comprehensive and detailed patterns of attributes for each feature in order to characterize each type of geological event. Occurrences of events are often associated with each other, particularly in tectonically active areas. Geological events affect both submerged and coastal environments. Data gathered by EMODnet Geology provide a good basis for further studies, contributing to the outlining of different tectonic settings and providing support to the use of marine resources, as well as to the management of marine-coastal areas particularly regarding the identification and assessment of geological and environmental hazards.

ABSTRACT We present the results of a compositional characterization study of amphorae from the ancient Greek town of Pharos, today Stari Grad, on the island of Hvar, in central Dalmatia, Croatia. The aim of the study was to identify the provenance of amphorae unearthed in Pharos, to determine the locally produced amphorae, and to identify the provenance of imported amphorae with a scientific-based approach, using optical thin-section petrography and bulk geochemical analysis by wavelength-dispersive X-ray fluorescence on 19 samples of different types of amphorae and reference materials. The results of the analyses allowed us to identify a group of imported amphorae from Corinth or Corfu and a group of imported amphorae from southern Italy, probably from Calabria. We were also able to identify a third group of imported amphorae from an as-yet-unknown provenance/workshop. Finally, according to the geochemical composition and close match with the reference material, namely, kitchenware, only two amphorae from the examined collection could be identified as local products. The results of the compositional characterization of amphorae from Pharos show us that an ancient Greek town had trade contacts beyond the Adriatic-Ionian region, and they provide opportunities for further studies of ancient amphorae production and circulation in this part of the Mediterranean.

Abstract We applied a computational method to aid in clustering 41 alluvial fans along the southern coast of the Gulf of Corinth, Greece. The morphology of the fans and their catchments was quantitatively expressed through 12 morphometric parameters estimated using geographical information system techniques and the relationships among the geomorphometric features of the fans and their catchments were examined. Self-organizing maps were used to investigate the clustering tendency of fans based on morphometric variables describing both the fans and their corresponding catchments. The results of unsupervised classification through the self-organizing maps method revealed correlations among the morphometric parameters and five groups of alluvial fans were identified. These groups had a clear physical explanation, showed a preferred geographical distribution and reflected the processes related to the development of the fans. The geographical distribution of the fan catchment groups was partially controlled by variations in the relative tectonic uplift rate, which was the main control on the accommodation space for the development and accretion of the fans. The smaller fans were located in the central part of the study area, where the uplift rates were higher, whereas larger fluvial-dominated fan deltas formed to the east and west of the central group, where the uplift rates were lower.
