We conducted a benchmark tests for the strong motion simulation methods using various theoretical methods (the wavenumber integration method, the discrete wavenumber method, and the thin layer method). For steps 5 and 6 in 2011, we conducted benchmark tests for actual sources in the Kanto sedimentary basin, such as the 1923 Kanto earthquake (M7.9). All the results generally show good agreements among simulations, but the surface waves seen in later part of observed ground motions were not reproduced well due to the limitation of use of flat-layered half-space models.
