Abstract
Present paper proposes two types of methods to estimate peak ground acceleration (PGA) based on questionnaire survey. The first method is to estimate PGA based on the method of estimating seismic intensity by questionnaire survey. The value of coefficient for seismic intensity is transferred to that for PGA using the relationshop between seismic intensity and PGA. The second methos is to estimate PGA using the questionnaire answer on TV motion during an earthquake. The TV motion and PGA relation are developed besed on results of DEM analysis. Both of proposed methods are applied to the area close to seismometer. The estimated PGA by the proposed methods were corresponding to observed PGA.
