memories because of their strangeness. Depending on the amount and quality of information collected, 323 cases were listed for further analysis. After dogs, earthworms were the most observed escaping from the ground and dying on the sidewalks surrounding buildings. This was observed up to six days before the shock. Whereas, dogs acted nervously few hours before. For animals only slightly smaller than dogs: hens, chickens and all birds in general, which were less frequently observed, the anomalous behavior was also reported several hours before the quake. In these latter observations, abnormal behavior was characterised by an unwillingness to return inside the hen house, their disappearance from certain areas and in their constant waking state. Cats were heard making strange meows in unusual places and straying from home with a little less frequency compared to birds. The cat behavior anticipated the shock by several hours. Therefore, one of the conclusions of this study is that the smaller the animal, the shorter the anticipation period (Fidani, 2013).
