Early Warning Systems (EWS) are tools designed to detect and alert communities about potential hazards, such as natural disasters like floods, earthquakes, or tsunamis. These systems use various technologies, including satellite imagery and weather monitoring, to gather data and predict events. By providing timely information, EWS help people prepare and respond effectively, potentially saving lives and reducing damage. EWS often involve collaboration between government agencies, scientists, and local communities. They may include communication methods like sirens, text messages, or social media alerts to ensure that information reaches those at risk. Effective EWS can significantly enhance community resilience against disasters.
