This leads to the hypothesis that only small amounts of water, present at depth within the mantle (on the order of 0.1 wt%), will lead to significant seismic attenuation and could potentially explain the anomalously low Q·¹ values which extend over a broad region in the mantle below Northeast Asia.
The hypothesis indicates that minimal water content, situated at depths within the mantle (about 0.1 wt%), could significantly impact seismic wave attenuation and may account for the anomalously low Q·¹ values found over an extensive region in the mantle below Northeast Asia.
