WebThe severity of shaking at a site is controlled primarily by two factors: earthquake characteristics and attenuation of ground motion. Attenuation is the dissipation of seismic energy as seismic waves move through layers of varying soil and rock strata. Also, once at a site, seismic waves can be modi ed by the site characteristics.
