When a disaster strikes, effectively informing the public to keep them safe becomes critical. But first, it’s essential to understand the full context to tailor the crisis communication accordingly.
There is no universal alert system
Choosing alert broadcast technologies depends on many factors:
- Nature and severity of the event: Is it a storm, cyclone, or earthquake? Is there a domino effect risk (e.g., an earthquake triggering a tsunami that affects industrial sites releasing toxic substances)?
- Number of people at risk: For example, geolocated SMS usually alert targeted at-risk populations precisely. For national alerts reaching millions, cell broadcast is preferred to avoid network overload.
- Time available to alert and respond: Are there seconds, minutes, hours, or days to react? The delivery method varies whether it’s a flood predicted in 48 hours or an earthquake that just occurred.
- Infrastructure in the area: What channels are available? Do most people have mobile phones? Does the network cover remote zones? Is radio well broadcast and listened to?
- Organizational capacity: Are authorities ready to act efficiently and in coordination? Are roles and responsibilities around communication channels clearly defined? Are crisis managers well trained on alert tools?
- Profile of the population concerned: Do they have access to mobiles? Are they connected to digital and traditional channels? Does illiteracy prevent some from understanding written instructions? Is the place frequented by many tourists without local SIM cards?
- Geopolitical context and trust in institutions: In conflict zones with fragmented information, people may distrust or reject official messages.
Multiply channels to leave no one behind
The real challenge lies in creating an alert system that integrates both technology and context. For extreme disasters or remote rural areas, a multichannel approach is essential.
- Mobile technologies - Cell Broadcast (CB) and location-based SMS (LB-SMS)—remain central for rapid, mass alerts when infrastructure permits.
Traditional channels (TV, radio, sirens) primarily reach older, isolated audiences or those outside mobile coverage.
- Digital tools (social media, official websites, apps, emails) effectively relay alerts before, during, and after crises.
- Satellites are also valuable relays when ground infrastructure is damaged or in cross-border incidents.
- Given this diversity, a hybrid approach is necessary. The most effective systems combine multiple channels, tailoring their use to the situation. For example, an initial alert may be sent via Cell Broadcast for speed, followed by detailed instructions through radio, social networks, or specialized apps.
AI, a vital ally when every minute counts
The challenge goes beyond choosing channels or technologies. Alert issuers need support, especially under stress where responsibility is heavy. Artificial intelligence acts as an assistant—not a replacement—but a catalyst to act confidently and efficiently.
At Intersec, we focus heavily on these issues. When used wisely, AI harnesses powerful analytics to serve people, ensuring the right information reaches the right person at the right time. Intersec.AI allows you to:
- Visualize risks and available resources in real time
