Earthquakes represent a real threat in Romania. They can cause important damages, loss of lives, socio-economic as well as cultural losses. The National Institute for Earth Physics (NIEP) is the only governmental organization responsible for monitoring the seismic activity on Romania?s territory. NIEP provides different kind of information minutes to hours after the occurrence of a significant earthquake in Romania: near realtime information (location, depth and magnitude), ground shaking parameters and maps with ...

In this paper, we analyze almost ten years of continuous recordings (November 2007? 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 minimu...
