- Description:
- For investigation of influence of various subsoil geological structures on spectral acceleration amplitudes of foundation soil it is necessary to continue in long time monitoring of near seismic events by using of large number of field accelerometers. The new special apparatus for automatic recording of spectral acceleration response was constructed. Principle of this apparatus is reverse pendulum with piezoelectric converter. This simple construction makes possible production numerous series with small requirements on capital expenditure and installation. The function of developed apparatus prototype was field-tested in station Prague - Květnice. Various seismic signals were recorded and also response amplitude of earthquake with focus near Červený Kostelec (10 October 2005, 10 : 51 : 57.4 ; M = 3.4; R = 156 km; φ = 50.47; λ = 16.07)., Jiří Buben and Vladimír Rudajev., and Obsahuje bibliografii
