Residents of Japan are used to receiving phone notifications of natural disasters such as earthquakes and tsunamis, but from next week the government will be able to warn them of a whole new threat. On Tuesday, the countrys Fire and Disaster Management Agency (FDMA) will flip the switch on a new alert system designed to relay information on nearby ballistic missile launches. Local governments can already receive the same missile data from the FDMA and notify citizens via loudspeaker or other means, but the phone notification system should prove more direct. North Korea fired missiles into Sea of Japan this week
