Modern technology has brought about a paradigm shift in public safety through the development of earthquake early warning systems relying on motion sensors built into smartphones. These systems transform devices into a global monitoring network that detects initial seismic waves and sends immediate alerts to users before destructive tremors arrive. Although this technology does not entirely replace traditional monitoring stations, it has proven highly efficient in providing a crucial time buffer to save lives in many countries, thus becoming an indispensable auxiliary tool in natural disaster management.
