| Zusammenfassung |
| An innovative newly developed modular and standards based Decision Support
System (DSS) is presented which forms part of the German Indonesian Tsunami
Early Warning System (GITEWS). The GITEWS project stems from the effort to
implement an effective and efficient Tsunami Early Warning and Mitigation
System for the coast of Indonesia facing the Sunda Arc along the islands of
Sumatra, Java and Bali. The geological setting along an active continental
margin which is very close to densely populated areas is a particularly
difficult one to cope with, because potential tsunamis' travel times are thus
inherently short. National policies require an initial warning to be issued
within the first five minutes after an earthquake has occurred. There is an
urgent requirement for an end-to-end solution where the decision support
takes the entire warning chain into account. The system of choice is based on
pre-computed scenario simulations and rule-based decision support which is
delivered to the decision maker through a sophisticated graphical user
interface (GUI) using information fusion and fast information aggregation to
create situational awareness in the shortest time possible. The system also
contains risk and vulnerability information which was designed with the far
end of the warning chain in mind – it enables the decision maker to base his
acceptance (or refusal) of the supported decision also on regionally
differentiated risk and vulnerability information (see Strunz et al., 2010).
While the system strives to provide a warning as quickly as possible, it is
not in its proper responsibility to send and disseminate the warning to the
recipients. The DSS only broadcasts its messages to a dissemination system
(and possibly any other dissemination system) which is operated under the
responsibility of BMKG – the meteorological, climatological and geophysical
service of Indonesia – which also hosts the tsunami early warning center.
The system is to be seen as one step towards the development of a "system of
systems" enabling all countries around the Indian Ocean to have such early
warning systems in place. It is within the responsibility of the UNESCO
Intergovernmental Oceonographic Commission (IOC) and in particular its
Intergovernmental Coordinating Group (ICG) to coordinate and give
recommendations for such a development. Therefore the Decision Support System
presented here is designed to be modular, extensible and interoperable (Raape
et al., 2010). |
