2001年インド西部地震におけるGandhidhamの建物被害

抄録

In order to investigate the cause of building damage concentration in Gandhidham city,the microtremor measurement on the soil surface and buildings are performed.None of the H/V spectra show a clear peak and the soil conditions cannot be accounted for the damage concentration from the microtremor measurements.However,from the survey it is inferred that the quality of construction and the number of stories may be related to the building damage.Furthermore,it is presumed that the earthquake motion intensity of Gandhidham was IX grade on MSK seismic intensity scale.
