Temperature Inversions and Sound Propagation
A temperature inversion occurs when warmer air is present above cooler air near the surface. Under these conditions, sound waves can refract, or bend, back toward the ground, allowing sounds to be heard at greater distances than under normal atmospheric conditions. While sound travels faster in warmer air, long-range sound propagation is influenced more by atmospheric structure and stability than by temperature alone.
Based on available weather observations from the evening of June 1, only a weak temperature inversion was present, accompanied by moderate winds. These conditions do not appear favorable for exceptional long-distance sound propagation.
Could the source have been Tannerite?
Yes, a Tannerite detonation remains a plausible explanation. However, based on the available meteorological data, atmospheric conditions alone would not be expected to significantly enhance the distance over which the sound traveled.
Could a Tannerite explosion account for reports from Danville, approximately 39 miles away?
While it cannot be completely ruled out, the available weather data does not strongly support unusually efficient sound propagation over that distance. Additional information regarding the size and location of any detonation would be required to assess that possibility with confidence.
Current Assessment
At this time, several explanations remain possible, including a large explosive event, a sonic boom, a meteor or bolide entering the atmosphere, or another unidentified atmospheric phenomenon. The widespread reports of a loud boom, along with accounts of windows, doors, and homes rattling across a broad area, suggest the event generated a significant atmospheric pressure wave.
Until additional evidence becomes available, no single explanation can be conclusively confirmed or ruled out. Further investigation and corroborating data will be necessary to determine the source of the event.
