Query: Simulation of seismic response in a city-like environment   We study the seismic response of idealized 2D cities, constituted by non
equally-spaced, non equally-sized homogenized blocks anchored in a soft layer
overlying a hard half space. The blocks and soft layer are occupied by
dissipative media. To simulate such response, we use an approximation of the
viscoelastic modulus by a low-order rational function of frequency and
incorporate this approximation into a first-order-in-time scheme. Our results
display spatially-variable, strong, long-duration responses inside the blocks
and on the ground, which qualitatively match the responses observed in some
earthquake-prone cities of Mexico, France, the USA, etc.
