MEAN reference Earth model is based on the Earth model IASP91. MEAN replaces IASP91’s mid-crustal discontinuity and Moho depth of 20 and 35 km to 18 and 30 km, respectively.

|Short Description||MEAN reference Earth model is based on the Earth model IASP91. MEAN replaces IASP91’s mid-crustal discontinuity and Moho depth of 20 and 35 km to 18 and 30 km, respectively. It also replaces IASP91’s a high S-velocity zone of the uppermost mantle (to the depth of 210 km) with a low S-velocity zone less than 4.5 km/s.|
