Seismic Hazard Calculation Efficiency in Earthquake Disaster Risk Survey
Abstract We investigate the calculation of seismic hazard with 120″, 60″, 30″, 15″, 9″ and 6″ grids respectively, and then interpolate the risk results of smaller grids. We compare the direct calculation of small interval results with those obtained by interpolation of larger spatial grids, and then evaluate the reliability, applicability and requirements of the results obtained by the larger spatial intervals. The results show that the calculated values of 30″ grid gives the results of various small grid results with an error of less than 1 Gal, which is a grid interval considering both accuracy and efficiency.
