| Zusammenfassung |
Fostered by and embedded in the general development of information and
communications technology (ICT), the evolution of tsunami warning systems
(TWS) shows a significant development from seismic-centred to multi-sensor
system architectures using additional sensors (e.g. tide gauges and buoys)
for the detection of tsunami waves in the ocean.
Currently, the beginning implementation of regional tsunami warning
infrastructures indicates a new phase in the development of TWS. A new
generation of TWS should not only be able to realise multi-sensor monitoring
for tsunami detection. Moreover, these systems have to be capable to form a
collaborative communication infrastructure of distributed tsunami warning
systems in order to implement regional, ocean-wide monitoring and warning
strategies.
In the context of the development of the German Indonesian Tsunami Early
Warning System (GITEWS) and in the EU-funded FP6 project Distant Early
Warning System (DEWS), a service platform for both sensor integration and
warning dissemination has been newly developed and demonstrated. In
particular, standards of the Open Geospatial Consortium (OGC) and the
Organization for the Advancement of Structured Information Standards (OASIS)
have been successfully incorporated.
In the FP7 project Collaborative, Complex and Critical Decision-Support in
Evolving Crises (TRIDEC), new developments in ICT (e.g. complex event
processing (CEP) and event-driven architecture (EDA)) are used to extend the
existing platform to realise a component-based technology framework for
building distributed tsunami warning systems. |
