Real time earthquake source parameters for Romania (2015- 2025)

This methodology uses the Brune spectrum (Brune et al 1970), the corner frequency and is applied to the S waves (method described in Gallo et al. 2014). The algorithm for estimating the seismic source parameters (M0, f0 and Mw) and ground motion parameters has been installed and configured in Antelope for Vrancea intermediate-depth earthquakes and for the crustal seismicity of Romania and is currently running at the National Institute for Earth Physics.

We have analyzed over 600 seismic events with 1.7≤ML≤6.0, recorded in Romania during 2004-2024, using the broadband and short-period sensors from the National Seismic Network department of the National Institute for Earth Physics (NIEP). All these results are obtained in a 5 minutes time interval after the occurence of an seismic event in Romania.
