Moreover, the disaster highlights the effects of wind and temperature profiles in the upper atmosphere on sound propagation, generating the phenomenon of "silence zone". These geographical zones, which in the case of Oppau were located about 100 to 200 km from the explosion site, are zones where no sound from the explosion was heard whereas the sounds of the explosion were heard in a wider radius (until nearly 300 km in a case study).
