タイトル(英): AMPLIFICATION FACTOR ESTIMATION USING THE RECORDS FROM SUPER-DENSE EARTHQUAKE OBSERVATION SYSTEM
抄録(英): A new realtime monitoring system ‘SUPREME’ by Tokyo Gas has about 3,700 earthquake observation sites. A map of SI-value during a large earthquake is estimated by interpolating observed values. It needs the site amplification factor at each observation site and at each 50m*50m grid point. In this paper, the amplification factors are estimated using the observed records of the new SI sensors, taking the ratio with the attenuation relationship obtained for each earthquake event using K-NET observation records. It is shown that the amplification factors of SI-value estimated by the mean S-wave velocity (AVS(20)) are in good agreement with the observation records, however, a map of observed amplification factor gives more detail information on the site effects.
