Warning earthquakes to every house

On Monday, Japan launched a state-of-the-art earthquake warning system, allowing anyone to hear on the radio or television a few seconds before a major earthquake occurred.

Special receivers that broadcast loud emergency messages can also be sold to families or workplaces. This ensures warnings can reach the people even in the night. The system is designed to let the listener be alerted 10 to 20 seconds, depending on the distance to the earthquake center.

This system has been used in Japan since 1989, to prevent train accidents in strong earthquakes. It is also used for other infrastructure systems, such as power plants. Now it is extended to the public.

Officials hope these warnings will make people safer. Although time is not long, it is enough to prevent people from being trapped in the elevator, allowing surgeons and other sensitive workers to stop, and for schools to prepare students. .
