500 Pound Military Bombs Source of Strange Noises Air Waves Shake Houses
It appears that the cause of strange noises and vibrations to houses in the Provost and Czar area recently were caused by 500 pound bombs being dropped.

Residents in the Provost and Czar area had reported unusual noises and even shaking of houses at nights.

Lt.-Colonel Paul Duff, base commander of Canadian Forces Base Wainwright told The News on May 6 that “I have confirmed that there was fighter aircraft activity, dropping 500 pound bombs on the two nights you mentioned. If weather conditions were right, then the concussion could have been heard out in your area. In the future, we will be placing public notices in advance of these kinds of exercises.”

A reader from near Czar called on May 5 suggesting the phenomenon was caused by activity at the base, approximately 50 to 60 miles by road from Provost.

An earthquake seismologist with Natural Resources Canada, John Cassidy of Sidney, B.C. was sent the recent newspaper stories to read. He replied stating that “I have checked out the dates and times mentioned in the articles on seismic records at our closest seismic station (to Provost and Czar)—that is a station near Edmonton. There were no obvious seismic signals . . . and we can pretty much rule out earthquakes. Most likely these are air waves shaking peoples houses and creating the noises.”

Owners of three houses in Provost described the mysterious shaking on the night of April 7 while later another man in Provost noticed a similar event at his house three times in recent weeks at around 11 p.m. His neighbour also reported the sensation one night at about 11:30 p.m.
