With the increasing intensity and frequency of extreme weather events, the need for efficient weather control systems alert for emergency situations is becoming increasingly crucial. In response to this demand, the Federal Government has launched a new pilot project that aims to improve communication with the population during disasters.
This system delivers alerts directly to users’ mobile devices, providing a vital tool for crisis management. In this article, we’ll explore how this new alert system works and what its main benefits and challenges are.
Operation of the New Alert System
A new alert system called Defesa Civil Alerta was recently launched and will be tested in 11 Brazilian municipalities. The initiative involves a collaboration between the Federal Government, the National Telecommunications Agency (Anatel), and the main mobile phone operators. The system uses the mobile phone network to send notifications with audible warnings that interrupt any content displayed on the user's screen. These alerts are designed to work even when the cell phone is in silent mode. This ensures that residents in risk areas receive crucial information without the need to register in advance.
The selected municipalities are Roca Sales (RS), Muçum (RS), Blumenau (SC), Gaspar (SC), Morretes (PR), União da Vitória (PR), São Sebastião (SP), Cachoeiro do Itapemirim (ES), Indianópolis (MG), Petrópolis (RJ) and Angra dos Reis (RJ). During the 30-day evaluation period, the operators and the National Civil Defense will monitor the functioning of the system to ensure its effectiveness and identify possible improvements.

Benefits and Operation of the Alert System
Civil Defense Alert provides several significant benefits for disaster management. First, the system allows alerts about natural disasters to be sent directly to the cell phones of people in risk areas, such as floods, landslides and storms. The technology is able to overlay these alerts on the content in use, and ensures that the message is seen immediately. Compatible devices are those with 4G or 5G coverage and that have updated operating systems, such as Android R or higher and iOS 17 or later versions.
Alerts are classified into two types of severity: extreme and severe. An extreme alert, which represents the maximum level of urgency, emits a loud siren-like sound, even in silent mode, to ensure that the alert is heard. A severe alert, on the other hand, uses a “beep” sound similar to that of an SMS, and, even in silent mode, it can be heard, but it is less intrusive.
Challenges and Additional Considerations
Despite the advantages, implementing Civil Defense Alert faces some challenges. It is essential to ensure that all compatible devices receive the messages correctly and that the system operates reliably during emergencies. Technical problems or network failures can compromise the effectiveness of the system. In addition, protecting user privacy is a constant concern. And citizens should be aware that there will be no charge for receiving the alerts. If they receive any request for payment related to these alerts, residents should verify the authenticity of the messages. To do so, they need to contact the institutions directly through official channels.
The new warning system is an important step towards improving disaster response and ensuring the safety of the population. The integration of modern technologies with risk management practices promises to provide an efficient tool. And, with this, it will be possible to face the growing threats of climate change and other types of emergencies.
