Effect of water on seismic attenuation of the upper mantle: The origin of the sharp lithosphere–asthenosphere boundary

C Liu, T Yoshino, D Yamazaki… - Proceedings of the …, 2023 - National Acad Sciences
Oceanic lithosphere moves over a mechanically weak layer (asthenosphere) characterized
by low seismic velocity and high attenuation. Near mid-ocean ridges, partial melting can …
