Possible Risk Reduction Measures
Risk Assessment
The evaluation of risk for a tropical cyclone is a relatively
straightforward process. A hazard map should be prepared for
any given year. The following information could be used to estimate
the probability of storms of cyclones of various intersections
that may strike different parts of the county.
|
|
Analyses
of climatologically records to determine how often tropical
cyclones have struck- their intensities and locations.
|
|
|
History of wind strengths,
frequencies, height and location of storm surges frequencies
of flooding.
|
|
|
Information about tropical
cyclone occurrences in the past 50-100 years over the ocean
adjoining the part of the country in question.
|
a) An Integrated Warning/Response System
Specific preparedness measures to counter the impact of tropical
cyclones may be classified into two categories:
|
|
Those of
long term or seasonal nature, which need to be planned,
implemented and operationally tested and co-coordinated
by means of simulation exercise well before a seasonal
threat commences. Among these are pre-season co-ordination
meetings at headquarters, district and local levels, at
which operational contingency plans are reviewed and amended,
training and community preparedness programs conducted
and community lifelines.
|
|
|
Those of a short-term
nature, which relate to a state of readiness to cut in
once a contemporary cyclone threat is announced. Among
these are domestic, vocational and animal husbandry arrangements
to safeguard the survival, property assets and livelihoods of
individual families and communities.
|
b) Public Warning System
The three main objectives in a tropical cyclone warning are:
|
|
To alert
the people to the danger by announcing the existence of
a threat due to a cyclone.
|
|
|
To identify the areas
where people will be actively threatened by cyclone and
where communities should monitor further warning
announcements, and
|
|
|
To call the people to
action by recommending specific preparedness activities,
which may be part of, and integrated warning/response
plan to protect vulnerable resources.
