the feedback from the community through the online commenting system
on the GEM website. They are: GEM Ontology and Taxonomy, Global
Exposure Database, Global Vulnerability Estimation Methods, Global
Earthquake Consequences Database, Inventory Data Capture Tools; all
these Global Components are now operative. It is noted that during this
fi rst 5-year phase of GEM, the emphasis will be placed on the seismic risk
of buildings (residential and commercial) due to budget and time con-
straints, whilst future extensions are expected to consider infrastructure/
lifelines.
Following a discussion and iteration process of more than a year related
to measurement and incorporation of socio-economic impact of earthquake
events, a project on social vulnerability and disaster resilience was initiated
at the start of 2012. The project directly supports GEM's mission of produc-
ing a holistic global earthquake risk model that integrates metrics of social
vulnerability and disaster resilience with the ongoing activities of hazard
and physical risk.
The ten Global Components as well as the project on social vulnerability
and resilience are described in more detail below, followed by a description
of the project on social vulnerability and disaster resilience.
30.2.1 Global Earthquake History
The Global Earthquake History is compiling an archive of historical earth-
quakes studies and a global parametric catalogue called Global Large
Historical Earthquake Catalogue (GLHECAT) containing events with
magnitude M
7.0 that occurred in the temporal window 1000 and 1903AD
(http://www.globalquakemodel.org/hazard-global-components/earthquake-
history).
The catalogue is compiled by critically merging catalogues (e.g. Utsu,
2002, or Dunbar, 2009) or datasets taken from published and publically
available material. The online archive of historical earthquake studies con-
taining, for each event, reports and macroseismic data points (when avail-
able) accompanies the information in the catalogue. The catalogue and the
archive of historical earthquake studies will build upon AHEAD, an archive
of earthquake data for Europe prepared in the context of the NERIES
project (see http://www.emidius.eu/AHEAD/main/).
This is a fi rst global collection providing for each event in the catalogue
a comprehensive compilation of the different most recent studies per-
formed as well as the original information studies referenced by the cata-
logue's authors to infer the main parameters describing the event. This
makes the present catalogue online an archive, a comprehensive collection
of historical earthquakes and to the greatest extent a dynamic database
updatable and improvable in the future. Moreover, this catalogue and the
