Olafsson and Sigbjornsson (1999)

Ground-motion model is: $log(amax) = ϕ1 + ϕ2logM0 - ϕ3log(R)$
where a_max is in cm∕s2, M₀ is in dyncm and R is in cm, ϕ₁ = 0.0451, ϕ₂ = 0.3089, ϕ₃ = 0.9642 and σ = 0.3148.
Instruments in basement of buildings located on rock or very stiff ground.
Records from 21 different stations.
Focal depths between 1 and 11km.
Most records from digital instruments with 200Hz sampling frequency and high dynamic range.
Seismic moments calculated using the strong-motion data.
Most data from M₀ ≤ 5 × 10²³dyncm and from d_e ≤ 40km.
