An initial attempt is made to determine whether infrasonic waves generated by storms of distant origin affect local human behavior. Severe storm activity in North America was compared with the automobile accident rate and the rate for absenteeism among school children in the area of Chicago Illinois during the first 28 days of May 1967. The results suggest that a correlation may exist between the presence of infrasonic disturbances in the Chicago area and changes in selected human behavior. It is urged that more comprehensive studies of this nature be carried out.
