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


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.


Some prerequisites for the construction of the SAT:

It 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 [...] ".

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 ...

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.

How can we build an early warning system in the Dominican Republic to reduce the vulnerability of the population to major

natural hazards in the country?

Hydrogeological risk

Seismic-geological risk

The main natural hazards affecting the Dominican society identified by the Technical Committee of the Early

Warning System are the risk hydrogeological and geological seismic risk

A case study:

EARLY WARNING SYSTEM FOR THE RISK HYDROGEOLOGICAL RIVER BASIN IN THE NUNEZ JUANA IN SALCEDO.


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.

Neighborhood of Las Mercedes, Salcedo. 2006.

In the district has identified several locations where people can go in times when the river level represents a real threat to them.

Identified weaknesses

Institutional strengthening (Civil Defense, COE, ONAMET, ...).Interagency information flow in real time

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 predictable (Hurricane Jeanne).
