DH Down-Hole C Deep deposits of dense or medium dense sand, gravel or stiff clay with thickness from several tens to many hundreds of m (Vs30=180–360 m/s). ES ESAC D Deposits of loose-to-medium cohesionless soil (with or without some soft cohesive layers), or of predominantly soft-to-firm cohesive soil (Vs30<180 m/s). / ) FK FK E A soil profile consisting of a surface alluvium layer with Vs values of type C or D and thickness varying between about 5 m and 20 m, underlain by stiffer material with Vs>800 m/s.
