“…There are two likely explanations for this discrepancy. Firstly, the results of Papadopoulos et al [2007] give the probabilities of tsunamis occurring somewhere in the eastern Mediterranean, whereas our results are for individual sites. Secondly, the observed catalog may contain tsunamis generated by submarine slides triggered by earthquake ground shaking.…”

“…They find that in this region, landslides generate more severe tsunamis, and that earthquake generated tsunamis are limited to wave heights of up to 1-3 m. This is in good agreement with the maximum PCTA values found for the Levant coast in this study. For a larger region in the eastern Mediterranean, Papadopoulos et al [2007] consider the observed tsunami history and find a mean recurrence of strong tsunamis (maximum wave height exceeding $4 m) of $142 years. Comparable tsunami waves are found in our hazard map for 0.02 annual probability (corresponding to a mean return period of 500 years), indicating a lower hazard level than that found by Papadopoulos et al [2007].…”

[1] Estimating the occurrence probability of natural disasters is critical for setting construction standards and, more generally, prioritizing risk mitigation efforts. Tsunami hazard in the Mediterranean region has traditionally been estimated by considering so-called "most credible" scenarios of tsunami impact for limited geographical regions, but little attention has been paid to the probability of any given scenario. We present here the first probabilistic estimate of earthquake-generated tsunami hazard for the entire Mediterranean Sea. We estimate the annual probability of exceeding a given tsunami amplitude at any coastal location in the region by applying a Monte Carlo based technique. Earthquake activity rates are estimated from the observed seismicity, and tsunami impact is derived from deterministic tsunami wave propagation scenarios. The highest hazard is in the eastern Mediterranean owing to earthquakes along the Hellenic Arc, but most of the Mediterranean coastline is prone to tsunami impact. Our method allows us to identify the main sources of tsunami hazard at any given location and to investigate the potential for issuing timely tsunami warnings. We find that the probability of a tsunami wave exceeding 1 m somewhere in the Mediterranean in the next 30 years is close to 100%. This underlines the urgent need for a tsunami warning system in the region.

“…Similarly, relatively small deviations of the growth axis angle and the differences in the lamina thickness and color seen in the stalagmite tip are largely consistent with historical earthquakes. These earthquakes, AD 334 Antioch, AD 341 Antioch, AD 344 Rhodes, and AD 365 Cyprus, had intensities of 9, 8, 9, and 9, respectively (Antonopoulos, 1980;Pararas-Carayannis, 2011;Erel and Adatepe, 2007;Papadopoulos et al, 2007;Sbeinati et al, 2005;Soloviev et al, 2000;Tinti et al, 2005). In literature, Rhodes was largely collapsed as a result of Rhodes Earthquake in AD 344.…”

Abstract:The study area is located in the central part of the Taurus Mountains, where karstification is widespread and strongly influenced by tectonic rise of the region and sealevel changes in the Mediterranean Sea during the Pleistocene. Young karstification in the area was largely affected by NE-SW trending left-lateral strike-slip faults and NW-SE trending discontinuities. The general extension of discontinuities is perpendicular to the faulting direction indicated by evaluation of the caves with the digital elevation model and lineament analysis. Findings of this investigation suggest that differences in the periodic development of the stalagmites are mainly due to tectonic movements. Therefore, the times of the growth-axis angle deviations for representative stalagmite samples from the Sakarlak Ponor and Kepez Cave were determined by U/Th analyses. The results tend to significantly overlap with times of historical earthquakes.

“…The catalogue was constructed following the format of the New European Tsunami Catalogue produced by a large group of specialists in a continuing effort within the frame of the EU GITEC, GITEC-TWO and TRANSFER research projects (e.g. Tinti and Maramai, 1996;Papadopoulos et al, 2007). A characteristic case is the key earthquake and tsunami event of 544/545 AD.…”
