Abstract
The seismic activity of Romania, is part of the Mediterranean-Asian seismic belt. It follows the chain of young mountains starting from Southern Europe, continuing through Turkey, Iran, the Caucasus and Central Asia. In this framework, the identification of series of strong earthquakes allows, through the application of advanced techniques of artificial intelligence and data science, to extract certain patterns of global, regional and local seismicity. Our paper has as final goal the forecast of crustal and subcrustal strong events in Romania, considering the application of advanced AI and Data Science techniques to extract hidden patterns from data sets, and to provide analytical arguments for the correlation of seismicity. We review seismic patterns involving adjacent tectonic plates, the migration of earthquakes along plate boundaries, but also intraplate seismic models involving Romanian crustal and subcrustal earthquakes. In the continent-continent collision between Eurasia, Africa and India we remarked not only eastward but also a westward migration such as the one in the years 2020-2022 originated in Indonesia and Myanmar then moving from Hindukush, Iran, East Turkey, Syria, West Turkey, and ended with a moderate intermediate depth earthquake in Vrancea. A much higher velocity migration of two month only started in the Indian Ocean, Indonesia, Iran and culminated in Turkey-Syria with the Mw 7.8 event of February 6, 2023. The highly debated connection of the crustal seismic activity from Vrancea and Targu Jiu, Romania, starting immediately after the 7.5 earthquake from Turkey (5.02.2023) will be discussed.
