Fidani cristiano.fidani@fisica.unipg.it Dipartimento di Fisica, Universitá di Perugia, Via A. Pascoli, Perugia, Italy A seven-month collection of testimonials about the 6 April 2009 earthquake in Aquila, Abruzzo region, Italy, was compiled into a catalogue of non-seismic phenomena. Luminous phenomena were often reported starting about nine months before the strong shock and continued until about five months after the shock. A summary and list of the characteristics of these sightings was made according to 20th century classifications and a comparison was made with the Galli outcomes. These sightings were distributed over a large area around the city of Aquila, with a major extension to the north, up to 50 km. Various earthquake lights were correlated with several landscape characteristics and the source and dynamic of the earthquake. Some preliminary considerations on the location of the sightings suggest a correlation between electrical discharges and asperities, while flames were mostly seen along the Aterno Valley. Alfano, G.
