EARTHQUAKE OF 30 OCTOBER 2020 IN THE AEGEAN SEA: NUMERICAL SIMULATION OF THE GENERATION AND PROPAGATION OF TSUNAMI WAVES

Abstract

The paper considers the earthquake in Samos on October 30, 2020 and the subsequent tsunami. Based on the data on both intensity of the earthquake and localization of the epicenter of the earthquake and aftershocks, taking into account the tectonic setting for this region, where active tension and shear deformations coexist, two possible sources of the earthquake were considered. Virtual sources have been constructed along the fault zone north of Samos. Using the keyboard model of the earthquake, the optimal kinematic movements of the keyboard blocks in the earthquake source were found, which most adequately describe the generation of the tsunami source and the propagation of tsunami waves to the coastal zone. 3D histograms of the distribution of the maximum wave heights along the coast were constructed and compared with the available field data and data from other authors.
