PREM has been widely used as the basis for [[seismic tomography]] and related global [[geophysics|geophysical]] models. It incorporates anelastic dispersion and [[seismic anisotropy|anisotropy]] and therefore it is frequency-dependent and transversely [[Isotropy|isotropic ]]for the [[Mantle (geology)|upper mantle]].

PREM was developed by [[Adam Dziewonski|Adam M. Dziewonski]] and [[Don L. Anderson]] in response to guidelines of a "Standard Earth Model Committee" of the [[International Association of Geodesy]] (IAG) and the International Association of Seismology and Physics of the Earth's Interior (IASPEI).<ref>{{cite journal|last=Dziewonski|first=Adam M.|coauthorsauthor2=Anderson, Don L.|title=Preliminary reference Earth model|journal=Physics of the Earth and Planetary Interiors|date=June 1981|volume=25|issue=4|pages=297–356|doi=10.1016/0031-9201(81)90046-7}}</ref> Other Earth reference models include IASPE91.
