- Location:
-
OXMT is located on Ox Mountain, near Half Moon Bay.
The site was installed under the auspices of
BFI Peninsula.
This site is known as SFOXM in the
USGS Low Frequency Network.
- Geology:
-
TBD
- Vault/Borehole conditions:
-
The MiniPBO borehole was installed on 02/06/2002. The strainmeter
was installed at 662.7 ft and the seismometer package at 637.3 ft depth.
This figure
shows the location of equipment in the borehole.
