PROGRAMA DE PREVENCIÓN Y PREPARACIÓN ANTE
DESASTRES NATURALES
Early Warning System
Are the provision of timely and effective
information through identified institutions, that
allow individuals exposed to a threat, taking
action to avoid or reduce their risk and
preparedness for effective response. Early
warning systems include three elements, namely
knowledge and hazard mapping, monitoring and
forecasting impending events, processing and
dissemination of understandable warnings to
political authorities and population, as well as
adoption of appropriate and timely action in
response to such alerts. What is the ultimate
goal of Early Warning System?Reducing disaster
risk in a society

PREVENTION PROGRAM AND DISASTER PREPAREDNESS
Early Warning Systems offer the possibility to
institutions and social groups vulnerable to the
risks of designing a coordinated action to
protect extraordinary range of events potentially
harmful.It is a tool (a means to an end) to
coordinate the alert or warning the population
that may be affected by a natural process
determined and institutional action. Improve
the responsiveness of a company upon the
occurrence of potentially harmful natural
processes and, ultimately, reduce disaster risk.

PREVENTION PROGRAM AND DISASTER PREPAREDNESS
Some prerequisites for the construction of the
SATIt is held in a cardinal pillar the
socialization of information. We refer to the
warning being delivered to a sector of the
population is exposed to risk in the occurrence
of a disturbing phenomenon and the mechanisms of
response (action strategy to deal with
potentially destructive natural phenomena).It
is imperative to train people to be able to react
when an alert is issued, otherwise the Early
Warning System will be completely useless.

"According to experts, if the countries affected
by the Indian Ocean tsunami had received a
warning system such as exists in case of eruption
and earthquakes in the Pacific Rim, the death
toll would have been much less than the 165,000
dead and 27,000 are reported missing so far, as
people have had time to save themselves by taking
refuge in areas near high ... ".Source News

What agencies are involved in an Early Warning
System?
Those agencies, higher education institutions,
NGOs and private entities that generate
information relevant to the establishment of an
efficient SAT and useful for the population
vulnerable to natural hazards.These organisms
may be related to meteorology, hydrology,
geology, seismology, environmental ...In the

What other elements are an early warning system?
A vital aspect for the efficient operation of
the SAT is the correct interpretation is made of
the information released. We refer to the
leaders, businessmen and people.
The efficiency of SAT depends on the
socialization of information (dissemination of
the alert) and the quality of the interpretation
of it.

society identified by the Technical Committee of
the Early Warning System are the risk

HYDROGEOLOGICAL RIVER BASIN IN THE NUNEZ JUANA IN
SALCEDO.

PREVENTION PROGRAM AND DISASTER PREPAREDNESS
Visit the Early Warning System for
hydrogeological risk of river basin Juana Nunez
de Salcedo, Dominican Republic.
The objective of the mission on 27 October was to
evaluate the current functionality SAT Salcedo, a
project implemented by the Italian NGO Movimondo
in 2004.
The area of ??the basin Juana Nunez covered by
the project is about 9 square kilometers. With a
North - South River runs for 9 miles and save a
drop of over 500 meters.
Three rainfall stations located in the upper,
middle and Salcedo, and a gauging station
(located in Salcedo also) feed a mathematical
model that estimates, based on the amount of
precipitation, if a flood occurs eventually
affect a sector of the population (neighborhood
of Las Mercedes and El Matadero).
The system provides a period of up to an hour to
work on the design of an action strategy to
danger.

in Salcedolessons Learned
Identified weaknesses
Data collection stations is performed manually by
volunteers who have no economic incentive.The
training was conducted under the project just
looked at the management software. The operator
(only two people have sufficient knowledge to
enter the data into the software) does not know
how it was designed and built the mathematical
model, therefore, are unable to conduct a review
and update.The small population served by the
SAT Salcedo.Reduced SAT test period (two years),
time in which only warned of a flood easily
