Analysis of the necessity and possibility of tsunami early warning on the Black-Sea coast

摘要

The catastrophic tsunami of December 26, 2004 in Southeast Asia revealed the necessity of creating tsunami early warning systems in the regions of the World Ocean where these systems are still absent but the potential hazard of tsunami generation exists. The Black Sea is one of these regions. We present the general characteristic of the tsunami hazard in the Black-Sea region and describe the most probable zones of tsunami generation, the specific features of tsunami propagation, and the parameters of tsunamis according to the data of observations and the results of numerical simulations. We also discuss the possibility of tsunami early warning on the basis of the operative data provided by the network of hydrometeorological and seismological observation stations existing in this region.
