Emergency communication systems are tools and technologies designed to quickly share important information during crises, such as natural disasters or public safety threats. These systems can include alerts sent via text messages, emails, or social media, as well as loudspeakers and sirens. Their primary goal is to keep the public informed and safe by providing timely updates and instructions. These systems often rely on various platforms, including cellular networks, satellite communications, and internet services, to ensure messages reach as many people as possible. Organizations like FEMA and local governments typically manage these systems to coordinate responses and disseminate critical information effectively.
