These seismic waves travel for great distances before finally losing most of their ... WebHá 2 dias · Hence, most of these can only simulate the vertical component. There is seldom a case for full wave-field simulation. To fill the gap, we simulate multi-component traffic-induced ambient noise by the two-dimensional finite difference method in this paper. Although only the vertical and radial components are simulated, it is enough for our study. phillongvpn.com
