Emergency alerts are notifications sent to the public to inform them about urgent situations that may pose a threat to safety. These alerts can be issued for various emergencies, including natural disasters like hurricanes and tornadoes, as well as man-made incidents such as terrorist attacks or chemical spills. They are designed to provide timely information and instructions to help people stay safe. These alerts can be delivered through multiple channels, including text messages, TV broadcasts, and radio announcements. In many countries, government agencies and local authorities are responsible for issuing these alerts, ensuring that communities receive critical information quickly during emergencies.
