Report to Air Force Office of Scientific Research about
a Regional Crustal Phase Observatory.
Document is 16 pages.
Dated: 14 Feb 1995 Written by James Edward Zollweg of Boise State University.
This document was originally categorized as ‘unclassified’.
This document updates the AFO on the project to re-activate the
Blue Mountains Observatory (BMO)in northeastern Oregon.
It gives a background of why the site was chosen, the original use of the Observatory, the existing structures that are being utilized, the new uses
when the upgrade is completed, the details of how and where the data will be directed for interpretation and archiving.
Background: BMO operated as a Vela
array from 1962 to 1975.
The military’s motivation for re-activating BMO is to develop their
ability to be the global monitor of nuclear tests…at the time of nuclear test bans
The primary function of the new BMO was to be used to develop the
methodology and test potential accuracy of Crustal Phase data collection, of the order
of 2 to 2.5 magnitude – to discriminate between small explosions and earthquakes
via focal depth determination.
The report explains that once the station is up and running, the data will
be digitized and directed via a duplex radio link to Boise State University where a receiver is mounted on the 8-storey Education building where the
information will be interpreted and archived, as well as accessible to other interested parties.
There are two diagrams, showing both the original array geometry plus the
new installation array geometry. There are also graphs of seismic data and maps
of the region showing seismic activity.
The report is quite legible and no blanked out areas.
