Early Warning System

 

 

Emergency situations require alerts to be transmitted as fast as possible to people in order to reduce the number of fatalities.

JRC's Early Warning System (or EWS) provides the local population with precise information about current events directly form the authorities, transmiting the urgency of the situation and alerting the locals to evacuate.

Com o Sistema de Alerta Antecipado, as fatalidades em situações de emergência podem ser muito reduzidas. No caso do terremoto japonês de 2011, por exemplo, temos que 60% da população soube da situação primeiramente através de um Sistema de Alerta Antecipado.

 

 

 

 

This is how the Early Warning System works: forecast data is sent through satellite to local governments, the data is analysed and if a threat is detected it is transmitted to the population through EWS.

 

COMMUNICATION METHODS

 

The system supports a variety of communication tecnologies to the siren and speakers. The methods bellow are the most comum:

 

Alert system through Digital Radio

The system uses Digital Radios with 60 MHz bandwidth. The local government uses it daily in communications with local communities and when providing evacuation alerts. This method was used in 2011's japanese tsunami.

 

 

 

 

 

 

 

Alert system through Broadcast Radio

The system uses already existing AM/FM radios. The warning station is equipped with AM/FM receivers with automatic activating function. If there is a radio station in the destination area, the signal can be transmitted through the already existing infrastructure. It is also possible to include a personal receiver in every house of the area.

 

 

 

 

 

Alert system through 3G/4G

The system uses 3G/4G modems and also digital rádios. Installed in Jakarta, Indonesia.
