Resolutions as adopted in Lisbon 2000
Data from historical monuments
Considering
that seismic hazard assessments depend generally on knowledge of the effects
of earthquakes over long periods of time (up to at least 500 years),
Recognising
that most historical records prior to 1900 are focused on damage to monumental
buildings such as castles, churches, mosques and towers,
The ESC recommends
that a basic ‘code of practice’ be established for the evaluation of the effects
of earthquakes on historical monuments taking into account their structural
integrity together with their regional and time dependent characteristics.
Macroseismic field investigation missions
Considering
that a damaging earthquake is a unique opportunity to collect pertinent data
which otherwise might be lost. This fact refers specially to macroseismic
data, which have to be collected in the immediate aftermath, before the cleaning
and reconstruction process has started,
The
ESC recommends
to explore possibilities that a field investigation team be formed for immediate
post-earthquake surveys collecting and evaluating macroseismic data;
the new EMS-98 scale, should be applied;
the data gathered on these missions is disseminated rapidly to the whole seismological
community via the Internet and subsequent publications
ESC countries welcome this initiative to explore the possibilities and identify
the difficulties of implementing such field investigating missions.
European institutions and other sources will be approached for financial support
under ESC auspices.
Thanks
Acknowledging
the hard work of the Local Organising Committee in arranging the XXVII General
Assembly of the ESC in Lisbon, and noting the success of the sessions, and
fruitful outcomes of many meetings and debates, the ESC Council
Thanks
the LOC for all their efforts in this city of the famous 1755 earthquake,
which have resulted in such a memorable conference.
