Abstract:

The redesigned triax seismometer module has been completed and transported to Fairbanks, Alaska, for operational tests. A triax borehole facility has been prepared at the Murphy Dome ALPA site 3-4 approximately 40 miles northwest of Fairbanks. The improved module and two of the engineering prototype modules operated at UBSO have been installed at site 3-4 and field evaluation is now in process.
