Effects of Low Flying Aircraft on Archaeological Structures

Induced vibrations from aircraft overflights were measured at Long House, an Anasazi Indian site dating from approximately AD 1300. Aircraft overflights were performed by RF-4C, A-7, and B-52 aircraft at altitudes ranging from 60 to over 300 meters AGL. Seismometers on the Long House structure recor...

Description
Summary:Induced vibrations from aircraft overflights were measured at Long House, an Anasazi Indian site dating from approximately AD 1300. Aircraft overflights were performed by RF-4C, A-7, and B-52 aircraft at altitudes ranging from 60 to over 300 meters AGL. Seismometers on the Long House structure recorded the site response. None of the overflights produced site responses exceeding established criteria for archaeological sites, taken to be a peak vector sum wall velocity of 1.3 mm/sec.
