Abstract
In 2004 a new seismic hazard map of Italy (MPS Working Group, 2004) has been released by a task force that produced an
amount of new or updated data, such as a new version of the earthquake catalogue (CPTI04; CPTI Working Group, 2004)
and an updated seismogenic zonation. A set of WebGIS tools has been designed for the data dissemination to the
scientific community and the general public.
The design of the WebGIS tools focused first on the consultation of the DBM04 macroseismic database (DBM Working
Group, 2005), which contains the macroseismic intensity data-points (IDP) of the earthquakes listed in the CPTI04
catalogue.
The WebGIS tool design and development process had to fulfill: 1) simplicity, 2) responsiveness and 3) readiness for
future extensions.
The specific requirements for the macroseismic database consultation interface were:
- data access by place and by earthquake;
- IDP maps with queryable points;
- data download in both tabular and map format;
- easily upgradable content;
- quick and user friendly interface
