Abstract:
The tsunami phenomenon is a worldwide natural hazard, triggered by various sources: submarine earthquakes and/or landslides, underwater volcanic eruptions and/or lava flows, aerial landslides, extra-terrestrial collision, or a mix of sources. Twenty-two tsunamis were documented in the Black Sea area in the past (Altinok, 1999). The first historical tsunami refers to an event generated in the 1st century BC, in Bisone, on the Bulgarian shore of the Black Sea (Nikonov, 1997). The earthquake with the highest magnitude generating a tsunami in the Black Sea was on 25th of December 1939, in Turkey, known as “Erzincan Earthquake”, having a magnitude M 8 (Yalciner, 2004). This event was generated onshore, 60 km away from the shore, still it had a high impact in the area. The most known tsunami from the western Black Sea was related to an earthquake of M 7.2, generated in Shabla area (Bulgarian shore) on 31st of March 1901, at a depth of 15 km. It has triggered tsunami waves of maximum 5 m height and also material losses (Papadopoulos et al., 2011). The most recent event was on 7th of May 2007, in the Bulgarian area of the Black Sea, with a non-seismic origin, probably following a submarine landslide (Ranguelov et al., 2008). Numerical simulations using Tsunami Analysis Tool (TAT) were accomplished for some areas from the Black Sea, where past earthquake parameters were available. Using these parameters (depth, location, focal mechanism) and recent information about the bathymetry of the Black Sea, tsunami modelling simulations were obtained for possible strong earthquakes. The results of these simulations could be compared with measured sea level data, in case of a future tsunami triggered in the area, and will be useful for improving the warning measures and prevention actions.
