“…As in all such cases, the data points were scattered below the upper bound lines for any given set of conditions. The attenuation characteristics agreed with data obtained at other sites by Oriard (1994).…”

“…Other similar measurements are shown in BuMin RI 8896 (Stagg et al, 1984). When the data from BuMin RI 8896 are plotted, a regression line would show that an outside temperature change of 27 degrees can generate strains in one of the gage locations approximately equivalent to more than 8 in./second (20 cm/second) ground vibration, as explained by Oriard (1994Oriard ( , 1999. Although that may come as a surprise to some, such relationships would have to exist to account for the extensive damage caused by these environmental forces.…”

There have been many studies of the human response to sound and vibration.…”

In response to public concerns about the damage potential of vibroseis vibrations from seismic exploration, Fina Oil and Chemical Company (now TOTAL E&P USA, INC.) sponsored full-scale testing of a typical residential dwelling. The test house was vibrated by four vibroseis trucks on both soil and asphalt surfaces at declining separation distances. Ultimately, the vibrators were only 13 feet from the front porch and 10 feet from the front sidewalk. Peak particle velocities of the ground motions were about 1 in/s at the house foundation. As expected, the responses of the superstructure were strongly dependent on the frequencies of the ground motions. No damage to the house of any kind was produced by these vibrations, even though the vibrators were operating at 90% maximum output. Tests were also conducted away from the house to explore the vibration intensities and attenuation characteristics of the ground motions generated. The resulting vibrations were compared to previous work and found to be consistent with those results (Oriard, 1994). Changes in crack width and associated weather-induced changes in temperature, humidity, and other environmental factors were recorded every two hours for one year. Environmental effects are known to produce larger crack responses than vibrations that conform to common standards and regulated limits. That fact was demonstrated again in
