Japan introduced automatic disaster warning system

On February 9, Japan introduced the automatic disaster warning system, which relies on satellites launched into orbit.

Thanks to this system, warning signals will be transmitted immediately to local authorities, helping to speed up the evacuation of people from areas at risk of disaster.

Through satellites, the system called "J-Alert " will transmit warning signals of natural disasters from the Japan Meteorological Agency (MA) to disaster prevention agencies in cities and towns. town; Automatically activate alarms and emergency radio systems in the localities.

This is really a big step, because now Japanese officials still have to start these systems themselves after receiving warning signals, so evacuation of people is often slow late.

During the first test on the morning of February 9, information sent from MA to a town in Western Japan reached its destination, but the emergency radio system did not work due to a computer software error. However, after fixing this error, the second test took place successfully.

According to the original plan, the above warning system will operate in 10 provinces and 4 Japanese towns. MA plans to expand the system to all localities of Japan, but has not set a timetable for promoting this plan.

Japan is one of the most seismic countries in the world. Every time in 5 minutes, there is a earthquake in this country. According to statistics, Japan accounts for 20% of earthquakes with magnitude of 6 degrees or more in the world.
