The authors have surveyed many damaged villages located at the epicentre of the ML=6.0 earthquake which occurred on August 24, 2016 in central Italy. Some unexpected anomalies were discovered such as very different levels of damage in Vezzano and Pescara del Tronto villages (Arquata del Tronto Municipality, Ascoli Piceno province). The two villages are situated just 1300 meters from each other. Pescara del Tronto suffered very heavy damage with many masonry building collapses and 48 fatalities, while Vezzano suffered only light damage to few buildings. This paper provides a preliminar analysis from an engineering and geophysics perspective. Particularly, rapid visual surveys were carried out in the two villages in order to detect possible significant differences in the vulnerability of their building stocks and site geophysical investigations were performed to detect possible local amplification effects.
