From Seismic Historical Information to Seismic Intensity Assessment through Fuzzy Set Theory

Abstract

To define the damages buildings have suffered due to the past earthquakes, the information we have at disposal is generally linguistic and often difficult to interpret. The present model aims to formalize the knowledge we get from historical data as well as its reliability. To formalize and to represent uncertainty, we have adapted some techniques realized in the frame of the Fuzzy Set Theory. The same techniques, once the damage has been defined, are used to carry out the evaluation of the macroseismic intensity of the earthquake in question.
