Zusammenfassung |
Warning systems commonly use information provided by networks of sensors able to monitor
and detect impending disasters, aggregate and condense these information to provide reliable
information to a decision maker whether to warn or not, disseminates the warning message
and provide this information to people at risk. Ultimate aim is to enable those in danger to
make decisions (e.g. initiate protective actions for buildings) and to take action to safe their
lives. This involves very complex issues when considering all four elements of early warning
systems (UNISDR-PPEW), namely (1) risk knowledge, (2) monitoring and warning service,
(3) dissemination and communication, (4) response capability with the ultimate aim to
gain as much time as possible to empower individuals and communities to act in
an appropriate manner to reduce injury, loss of life, damage to property and the
environment and loss of livelihoods. Commonly most warning systems feature strengths
and main attention on the technical/structural dimension (monitoring & warning
service, dissemination tools) with weaknesses and less attention on social/cultural
dimension (e.g. human response capabilities, defined warning chain to and knowing
what to do by the people). Also, the use of risk knowledge in early warning most
often is treated in a theoretical manner (knowing that it is somehow important),
yet less in an operational, practical sense. Risk assessments and risk maps help to
motivate people, prioritise early warning system needs and guide preparations for
response and disaster prevention activities. Beyond this risk knowledge can be
seen as a tie between national level early warning and community level reaction
schemes.
This presentation focuses on results, key findings and lessons-learnt related to tsunami
risk assessment in the context of early warning within the GITEWS (German-Indonesian
Tsunami Early Warning) project. Here a novel methodology reflecting risk information
needs in the early warning context has been worked out. The generated results
contribute significantly in the fields of (1) warning decision and warning levels,
(2) warning dissemination and warning message content, (3) early warning chain
planning, (4) increasing response capabilities and protective systems, (5) emergency
relief and (6) enhancing communities’ awareness and preparedness towards tsunami
threats. Additionally examples will be given on the potentials of an operational
use of risk information in early warning systems as first experiences exist for the
tsunami early warning center in Jakarta, Indonesia. Beside this the importance of
linking national level early warning information with tsunami risk information
available at the local level (e.g. linking warning message information on expected
intensity with respective tsunami hazard zone maps at community level for effective
evacuation) will be demonstrated through experiences gained in three pilot areas in
Indonesia.
The presentation seeks to provide new insights on benefits using risk information in early
warning and will provide further evidence that practical use of risk information is an
important and indispensable component of end-to-end early warning. |
