Early Warning System (EWS) for Natural Disaster

Nearly a million people have been killed over the last decade by disasters caused by storms, droughts, floods. While some material losses seem to be unavoidable, especially in the case of very large and infrequent events, in some cases the loss of human lives could have been avoided if the proper precautions and measures had been in place. This would have been the case for the December 26, 2004 Indian Ocean tsunami, which provoked fatalities surpassing a quarter of a million people.

In Indonesia, over 250,000 people lost their lives due to the lack of a tsunami early warning system. While there would have been sufficient time to warn some of the coastal population, the lack of awareness regarding tsunamis, the lack of an early warning system, and the lack of training to respond to a warning inhibited the authorities and the local population from executing the proper measures which would have significantly reduced the loss of lives.

A Solution based on Fusi Technology

Many country is threatened by the natural disaster, and several have already built subsystems for forecasting and monitoring natural phenomena, which are administered by specialised institutions. Our proposed solution consists in the addition of an acoustic warning subsystem to such forecasting and monitoring system, and the interconnection of the systems. Regarding the necessity to cover large and broken-relief territories, the satellite data transfer is the most suitable control and communications method, which can be supplemented, if necessary, with the backup radio or GPRS data transmission from ground-based transmitters. If the siren is equipped with a local control unit, not only can it be used for warning inhabitants against an impending danger, but also directly on site afterwards by rescue teams for managing their operations and communications on the affected territory. A similar warning system can be successfully used also in case of other natural disasters such as tornadoes, fires, volcano eruptions, or earthquakes.

"Natural disaster in the last decades, to represent a high risk for many country. Early warning systems that consist of sensor forecasting and monitoring subsystems can eliminate casualties on the local population."

A monitoring system

A monitoring system consisting of a set of sensors for the detection of a developing natural disaster. The sensors can be directly connected to the Pavian electronic siren and the data obtained transferred to the control centre.

Satellite data transfer for the activation of individual sirens and the data transfer from the monitoring system to the control centre.

Control and command center

Control centres intended for the analysis of the data obtained and equipped with the software. The software allows the sirens status control and activation, control of data transfer channels, and the notification of authorised persons. The system can be hierarchical, with several levels, such as the main warning centre and local subordinate centres. These centres, if desired, can be designed as unattended or remotely-controlled by smartphone, tablet, or radio.
