The Japan Meteorological Agency (JMA) provides residents in Japan with Earthquake Early Warnings. This is a new system that issues prompt alerts just as an earthquake starts, providing valuable seconds for people to protect themselves before strong tremors arrive.
On 1 October 2007, JMA launched the Earthquake Early Warning service for provision through a number of media outlets such as TV and radio.
