Biological Anomalies around the 2009 L'Aquila Earthquake.

Fidani C - Animals (Basel) (2013)

Bottom Line: Around the time of the seismic swarm many instruments were operating in Central Italy, even if not dedicated to biological effects associated with the stress field variations, including seismicity.Data on animal behavior, before, during and after the main shocks, were analyzed in space/time distributions with respect to the epicenter area, evidencing the specific responses of different animals.Several instances of strange animal behavior were observed which could causally support the hypotheses that they were induced by the physical presence of gas, electric charges and electromagnetic waves in atmosphere.

ABSTRACT
The April 6, 2009 L'Aquila earthquake was the strongest seismic event to occur in Italy over the last thirty years with a magnitude of M = 6.3. Around the time of the seismic swarm many instruments were operating in Central Italy, even if not dedicated to biological effects associated with the stress field variations, including seismicity. Testimonies were collected using a specific questionnaire immediately after the main shock, including data on earthquake lights, gas leaks, human diseases, and irregular animal behavior. The questionnaire was made up of a sequence of arguments, based upon past historical earthquake observations and compiled over seven months after the main shock. Data on animal behavior, before, during and after the main shocks, were analyzed in space/time distributions with respect to the epicenter area, evidencing the specific responses of different animals. Several instances of strange animal behavior were observed which could causally support the hypotheses that they were induced by the physical presence of gas, electric charges and electromagnetic waves in atmosphere. The aim of this study was to order the biological observations and thereby allow future work to determine whether these observations were influenced by geophysical parameters.

Mentions: Grasshoppers invaded the L’Aquila area three months after the main shock. It was reported to be a biblical sight on July 15, 2009. Millions of grasshoppers had invaded the territory of the epicenter starting from Bazzano and Onna and diffusing in Sant’Elia, San Gregorio, Barisciano, Poggio Picenze, Raiano, Pianola and Preturo. The insects were found in hundreds of buildings and camping sites. The health authorities disinfected the areas and the phenomenon decreased at the beginning of August. Live grasshoppers were taken and examined. Results from this analysis showed that the orthoptera were not dangerous for humans and in this case did not harm the cultivation, see Figure 3. It was determined by health authorities [36] that the grasshoppers proliferated in a recently cut grassed area near Bazzano due to the high temperature and humidity. It could be hypothesized that this proliferation was due to soil degassing which was reported to have occurred [37,38]. Grasshoppers invaded the villages of Fontecchio, Fossa, Onna and Bazzano from the city of Popoli along the Valle Peligna.
