Report on broad-band stations on topography in Italy

Abstract

In Italy, a large part of the national territory is affected by significant topographic variations (grey scale variations of Fig.1). Inevitably, many stations of the Italian Seismic Network (a total of more than 250 broad-band seismological stations) are installed on topographic irregularities. The frequent seismicity of Italy (Fig. 1) produces a useful data set for a comparative study of effects caused by typical topographic shapes (e.g. ridges and cliffs). This report illustrates criteria adopted for the station selection and methods to be used in NERA for the characterization of station topography and site amplification.
