The objective of this project is the microzonation of the Bucharest city (Romania). For a better understanding of the geological structure under Bucharest, non-invasive methods are used, as: wavelet-polarization analysis at each station, H/V for ambient vibrations and earthquakes, and the three-components array analysis of ambient vibration recordings from URS experiment, in order to retrieve the characteristics of surface waves. Surface wave dispersion curves, their ellipticity and the data from boreholes (depth < 100m) are jointly inverted to estimate the velocity structure under the city. The final 3D structure will be used for the numerical simulation of the seismic waves propagation from the Vrancea intermediate-depth source to the city in order to investigate the seismic hazard in the city. Data used in this project are from: National Institute of Earth Physics, CRC461-Proiect URS – URban Seismology 2003-2004, BIGSEES ”BrIdging the Gap between Seismology and Earthquake Engineering: from the Seismicity of Romania towards a refined implementation of seismic action EN1998-1 in earthquake resistant design of buildings” |
