Abstract
Volcanic eruptionsand earthquakes in the Christiana-Santorini-Kolumbo rift have repeatedly triggered devastating tsunamis including the 1600 BC Late Bronze Age eruption of Santorini, the 1650 eruption of Kolumbo and the 1956 Amorgos earthquake. The Late Bronze Age eruptiontsunami affected large areas of the eastern Mediterranean and contributed to the demise of the Minoan culture on Crete, while the effects of the 1650 Kolumbo and the 1956 Amorgos tsunamis were limited to the islands around the Christiana-Santorini-Kolumborift. Although intensively studied in recent decades, the potential tsunami source parameters of these events remain poorly constrained. The THESEUS project aims to parameterize various potential source parameters associated with these tsunami events using marine high-resolution reflection seismics. For this purpose, we conducted high-resolution 2D and 3D reflection seismic surveys as well as ocean-bottom seismometer refraction seismic experiments covering the Christiana-Santorini-Kolumbo rift during expedition POS538 onboard RV Poseidon in October 2019. Here, we present the first results of the ongoing analysis of our P-Cable 3D seismic dataset, which covers most of the Kolumbo volcanic edifice and a prominent fault zone to the north. In addition, we present 2D seismic profiles covering the Santorini Caldera and pyroclastic flow deposits associated with the Late Bronze Age eruption
