Figure 2. Lithologic map of the urban area of Rome together with the distribution of the damage caused by the 1915 Fucino earthquake (after Ambrosini et al., 1986). Three types of damage are distinguished: slight damage (cracking of plaster, the downfall of small pieces of moldings), intermediate damage (between slight and heavy damage), and heavy damage (deep and diffuse damage of indoor and outdoor walls, downfall of large parts of moldings and of chimneys).
