Ground electric field effects on rats and sparrows : Seismic anomalous animal behaviors (SAABs)

Electric field effects on behaviors of albino rats, Mongolian gerbils (sand rats), hair-footed Djungarian hamsters, guinea pigs and red sparrows (Avadavat) have been investigated in order to determine whether seismic anomalous animal behaviors (SAABs) witnessed prior to a major earthquake are due to...

Description
Summary:Electric field effects on behaviors of albino rats, Mongolian gerbils (sand rats), hair-footed Djungarian hamsters, guinea pigs and red sparrows (Avadavat) have been investigated in order to determine whether seismic anomalous animal behaviors (SAABs) witnessed prior to a major earthquake are due to seismic electric signals (SES). Animals placed on a wet conductive floor initially showed grooming, nervous and field avoidance behaviors and finally ran and jumped in panic as the ground field intensity was increased from 1 to 1000 V/m. An electromagnetic model of a fault, in which piezo-compensating bound charges appear as a result of sudden reduction of the piezoelectric polarization due to the release of seismic stress, gives sufficient field intensity to produce a critical body current of a few µA. It is considered that animals showed electrophysiological responses to seismic current.
