Seismic Precursory Phenomenology in Unusual Animal Behaviour in Val Pellice, Western Piedmont, in Comparison with Anomalies of Some Physical Parameters

摘要

The unusual animal behaviour, often observed before earthquakes in a moderate seismic area in Western Piedmont (NW Italy), can be connected with the anomalies of some physical parameters, recorded in a multiple parameters monitoring. Physical phenomena such as radioactive decay, gas emission, soil temperature increase, water pH variations in creeks and lakes, magnetic declination anomalies, air electricity and infra-sound, can generate damages to biological structures or, sometimes, death. A multiple parameters physical monitoring started recently in Western Piedmont, which is useful to propose the study of seismic precursors possibly linked to animal behaviour. Observations of unusual animal behaviour as vocal communications and movements were collected in the same area. A statistical analysis of strange behaviours in dogs and cats may indicate the probable early warning factor of the sense of smell.
