Inbuilt models

Most users of SeisModels will probably want to simply calculate properties for one of the inbuilt models, which are all exported. These are listed below:

Earth models

SeisModels.Earth.AK135 — Constant

AK135

1-D layered model of the Earth, containing density.

SeisModels.Earth.EK137 — Constant

EK137

1-D layered model of the Earth, containing density.

SeisModels.Earth.IASP91 — Constant

IASP91

1-D model of velocity.

N.B. iasp91 does not contain density.

This version of the model uses the original coefficients and is a PREMPolyModel as published. Other implementations available may use a layered piecewise linear model and/or add density from other sources.

SeisModels.Earth.PREM_NOOCEAN — Constant

PREM_NOOCEAN

Version of PREM where the liquid ocean layer is replaced by the crust beneath. This model may be useful when the surface must be a solid.

SeisModels.Earth.SC_REM_25_LOW — Constant

SC_REM_25_LOW

Retracted model

The SCREM25_LOW model has been retracted by the authors and is only retained in SeisModels to retain compatibility. Future major versions of SeisModels may remove this model.

Lower bound of the 25% credible interval of the SC-REM model of Kemper et al. (2023).

SeisModels.Earth.STW105 — Constant

STW105

1-D layered model of the Earth, containing radial anisotropy, density and attenuation.

Attenuation is taken from QL6 (Durek and Ekström, 1996).

This version was obtained from: https://ds.iris.edu/ds/products/emc-stw105/ The original model is parameterised by radial splines.
