Title: Effects of a major earthquake on the PEP housing, structures, and utilities

Technical Report ·
DOI:https://doi.org/10.2172/6430961· OSTI ID:6430961

The PEP tunnel, above-ground structures, and utility structures have been designed to withstand a major earthquake. This means they will experience minor or moderate damage in an earthquake which will cause widespread devastation in the surrounding region. The earthquake on October 17, 1989, which was not very severe locally, caused no damage to the PEP tunnel, buildings, or utilities. There was apparently some permanent displacement of the PEP tunnel. The PEP ring magnets moved enough to require re-alignment. A major earthquake will probably cause sufficient displacement of the PEP tunnel and magnet systems to necessitate extensive re-alignment. This may be the dominant factor determining the length of the shutdown after the quake.
