Increasing Seismic Safety by Combining Engineering Technologies and Seismological Data
Introduction
The current state-of-the-art allows seismologists to give statistical estimates of the
probability of a large earthquake striking a given region, identifying the areas in
which the seismic hazard is the highest. However, the usefulness of these estimates
is limited, without information about local subsoil conditions and the vulnerability
of buildings. Identifying the sites where a local amplification of seismic shaking
will occur, and identifying the buildings that will be the weakest under the seismic
shaking is the only strategy that allows effective defence against earthquake damage
at an affordable cost, by applying selective reinforcement only to the structures that
need it.
