| Research Abstract |
I tried the strong motion evaluation of the Katmandu Basin that was the world heritage area of the Nepalese country. I evaluated basement structure in cooperation with an expert of the local geological feature, seismology.
I started strong motion observation inside and outside of the basin. I estimated the shallow underground structure near the observation sites by the surface wave exploration method. High quality strong motion data was recorded in each site. I could confirmed these time series data and spectra with the shallow underground structure for each sites. These data which were recorded in Katmandu Basin and a penumbra for the first time will be important basics data to a strong motion prediction in the future.
