ABSTRACT
This chapter presents the application of ground-penetrating radar (GPR) in the ancient harbour of Falasarna in north-western Crete. Even though the Ancient Falasarna archaeological site includes a series of man-made constructions, such as bridges, towers and water tanks, here we present only the results from the vicinity of the harbour. GPR proved to be very efficient in tracing the lateral extent both of the harbour's main jetty and of the tsunami sediments, deposited in the area during two major historical seismic events. Based on excavated trench sedimentological evidence, a surface layer of fine-grained (silt and clay) deposits containing angular gravel fragments and terrestrial molluscs overlies a distinct layer containing a mixture of gravel, sand, shell fragments and flattened clasts that represent the tsunami deposits, triggered by the AD 66 and in all likelihood by the AD 385 earthquakes too.
