A crustal LVZ in Iceland revealed by ambient noise multimodal surface wave tomography

Frontiers in Earth Science, 2022
The crustal low-velocity zone (LVZ), an important anomaly found in some regional structures of Iceland, is still absent in the Icelandic average velocity structure due to limitations of tomography methods.
