ABSTRACT: Twelve sites were investigated where unexplained footsteps, apparitions, electrical disturbances, strange behavior by pets, and other haunt phenomena had been reported. Recordings were made of the local geomagnetic fields (GMFs), electromagnetic fields (EMFs), and ion densities. On the basis of previous studies it was predicted that the sites would exhibit anomalous EMFs or GMFs. Ten of the sites showed such anomalies. At three sites there were intense, transient EMF increases. At one of these the anomaly was attended by a drop in temperature and an apparitional sighting by one of the investigators. At one site an intense and constant EMF overlapped with an intense local GMF. The remaining eight sites showed normal EMFs, except in proximity to electric installations. Six sites exceeded the norm for GMFs by...
