southern and western coasts of Sumatra, Java and Bali. Although a
Tsunami Early Warning Center in Jakarta now exists, installed after the
devastating 2004 tsunami, it is essential to develop tsunami risk knowledge
within the exposed communities as a basis for tsunami disaster management.
These communities need to implement risk reduction strategies to mitigate
The major aims of this paper are to present a risk assessment methodology
which (1) identifies areas of high tsunami risk in terms of potential loss
of life, (2) bridges the gaps between research and practical application,
and (3) can be implemented at community level. High risk areas have a great
need for action to improve people's response capabilities towards a disaster,
thus reducing the risk. The methodology developed here is based on a
GIS approach and combines hazard probability, hazard intensity, population
density and people's response capability to assess the risk.
Within the framework of the GITEWS (German-Indonesian Tsunami Early Warning
System) project, the methodology was applied to three pilot areas, one of
which is southern Bali. Bali's tourism is concentrated for a great part in
the communities of Kuta, Legian and Seminyak. Here alone, about 20 000
people live in high and very high tsunami risk areas. The development of
risk reduction strategies is therefore of significant interest. A risk map
produced for the study area in Bali can be used for local planning
activities and the development of risk reduction strategies.
