GEOPHYSICAL INVESTIGATIONS OF TERRESTRIAL TSUNAMI DEPOSITS AT CAESAREA MARITIMA, ISRAEL
Our 2018 fieldwork sought to advance current understanding of the spatial distribution, architecture, and stratigraphic relationships of sedimentary units as related to tsunami events at Caesarea Maritima. The team employed ground-penetrating radar (GPR) and frequency domain electromagnetic (FDEM) techniques to elucidate the subsurface architecture. GPR has increasingly become a favored tool in research on past tsunami activity, due to its capacity for visualization of deposits both in terms of internal structure and lateral extent. FDEM is a useful complement to GPR, providing rapid characterization of sediment composition over a landscape, and allowing for differentiation between types of sedimentary deposits. During our field campaign, we generated GPR and FDEM profiles for coastal areas to the north, south, and inland of Caesarea, targeting areas with high potential for preservation of tsunami deposits such as the Herodian hippodrome and agricultural plots. Here we present initial interpretations of the geophysical data, and integrate the results with the previously conducted research to improve understanding of potential tsunami inundation history and deposit preservation in archaeological contexts.
