A total number of 22 tsunamis were generated in the Black Sea in the past, as stated in the literature. Three from the twenty-two events were triggered by earthquakes occurred in Shabla area, the most dangerous one for the Romanian and Bulgarian shores, as follows: the oldest one, in Bisone area, 1st Century BC; year 543-544 AC, an earthquake of 7.5 M triggered waves of 2 - 4 m; the most recent, on 31st of March 1901, a 7.2 M earthquake generated 2.5 - 3 m tsunami waves, or 5 m according to other sources. The TRID...

In this paper, we analyze almost ten years of continuous recordings (November 2007пїЅ April 2017) from 114 stations of the Romanian Seismic Network using the power spectral densities and their corresponding probability density functions (PSD PDF). For each vertical station component, we compute the statistical mode for noise levels from the PSD PDFs. The noise mode represents the highest probability noise level for a given station. We then construct the PSD PDF mode low-noise model for Romania (RONM) from the mini...
