FDSN Network Information

FDSN code XA (1995-1996) Operated by IRIS/PASSCAL
Network name Missouri to Massachusetts Array (MOMA) Deployment region
Start date Jan. 1, 1995 End date Dec. 31, 1996
Short description

In the MOMA experiment, 18 BB seismometers were deployed between permanent IRIS/GSN stations CCM (Catherdral Caves, MO) and HRV (Harvard, MA), providing a linear 20-station array spanning 1740 km. The goal of the experiment was to obtain new information about the structure of the core-mantle boundary, the structure of the crust and mantle beneath the eastern US (including mantle discontinuities, mantle anisotropy, and lateral velocity variations), and the structure of subduction lithospheric slabs.
