Shear-Wave Splitting Beneath MOMA

Shear wave splitting measurements were taken at MOMA and other eastern North American stations to examine the continental keel and patterns of mantle flow. [Fouch et al., 2000]

Anisotropy at the Base of the Mantle from SHdiff/SVdiff Waves

Differences bewteen the SHdiff and SVdiff waves observed at MOMA stations are used to examine the horizontal and vertical anisotropic variations in the D” layer beneath the mid-Pacific. [Fouch et al., 2001] [Fouch et al., 2002]
