People in the UK are to be sent text message alerts warning them of local terror attacks, fires and floods.
The system is to be trialled in Suffolk and if it works it will be rolled out across the country, reports the Daily Mail.
The first trial of the system, based on the same technology that alerts people to Covid spikes in their area, will take place this month.
The system will send a message to anyone in the vicinity of appropriate mobile phone towers - including people who enter the area after the initial alert is sent.
Messages should arrive with 10 seconds - with a loud tone and vibration.
Similar systems are already in use across North America, east Asia, Holland and New Zealand.
Cabinet Office Minister Penny Mordaunt told the Mail: "The Emergency Alerts Service will be a vital tool in helping us to better respond to emergencies, both nationally and locally.
"[It] will allow us to more quickly and effectively get life-saving messages to people across the UK."
The first message will be tested on May 25.
