In Italy, three main Institutions are active in
the field of seismology and earthquake engineering

SIGE - Informative System for Emergency
Management and simulation scenarios

• After a seismic event it is very important to
  recognise the dimension of the problem as soon as
  possible. Particularly useful is the use of a
  G.I.S.
• In case of an earthquake, of magnitude 5 or more,
  an automatic procedure is immediately activated
  by SSN to produce data, maps, and information
  concerning the epicentral area
• On the basis of attenuation relations , several
  ground motion parameters (intensity, PGA, PGV,
  spectral values) are calculated for each
  municipality within a radius of 100 km from the
  epicenter. These values are used to give a
  preliminary evaluation of the damages and losses
• Several maps and data, giving a complete
  description of the main features of the stricken
  area are transmitted, within one hour, to the
  Civil Defence Department

Emergency management

• MAPS OF THE EPICENTRAL AREA
• event localization
• historical epicenters in the area and
  seismogenetic zones
• isoseismal of the historical earthquakes
• strong-motion and seismometric networks
• expected values of macroseismic intensity
  (attenuation from the epic.)
• expected values of PGA, PGV, and spectral
  acceleration (attenuation from the epic.)
• resident population
• population density
• distribution of dwellings in different
  vulnerability classes (A, B, C - MSK)
• dwellings built before the enforcement of the
  building code
• hospitals per municipalities
• classrooms in primary and secondary schools
• risk industries
• landslide vulnerability
• road and railway network, lifelines
• expected structural damage (collapsed,
  uninhabitable and damaged dwellings, damaged
  surface, monetary loss)
• expected number of casualties (fatalities and
  homeless)

UMBRIA MARCHE EARTHQUAKE September 26, 1997 Real
values verified on field and values predicted by
the scenario
The values relative to the number of victims are
strongly overestimated, whereas the number of
homeless, unusable dwellings and monetary loss
are closer to the real values. This is probably
due to the fact that the strongest shock (Ms5.9)
happened at 11.40 a.m. and was preceded by a
weaker shock (Ms5.5) at 2.33 a.m., giving to the
people the possibility of running out of their
homes. It's also interesting to note that the
effective number of unusable dwellings is higher
than the number of homeless people, due to the
fact that this figure includes any kind of houses
(rural, industrial, commercial activities, etc.)
many of whom uninhabited. Considering the amount
of uncertainties, in hazard, vulnerability, an
loss assessment, the aim of this scenario
evaluation was just to provide the order of
magnitude of damages and losses expected in
different parts of the Italian territory.
Improvements in hazard and vulnerability
assessment, estimation of losses to facilities
and lifelines, evaluation of indirect losses and
induced phenomena, will be the subject of future
investigations.

DAMAGE SURVEY AND SAFETY ASSESSMENT

• Procedure
• residents ask the Major for survey
• Operative Center send technical teams
• technicians assess buildings damage safety
• Major decides on the buildings evacuation and
  provisional safety works
