خلاصه مقاله:

We develop a methodology for a shakemap for the Romanian capital Bucharest that can be rapidly computed and delivered to the public, once real-time data access is available to a sufficient extent. A systematic incorporation of previous seismological observations of weak and strong ground motion and a recent urban broadband experiment in Bucharest allows us to interpolate computed seismic intensities from 11 sites, where accelerometers measure the actual motion of a specific earthquake to 31 additional locations in the city, so that a reasonably reliable distribution of ground motion in the city can be determined. We demonstrate this methodology using the MW = 6.0 intermediate-depth earthquake of October 27, 2004.
