Update information Edit(Apr.16)
Last night, when I rested at ease in my living room, my cellular phone suddenly set up a shout: “Earthquake!, Earthquake!”. I picked it up, and shakiness began when I only read the first few letters of “Earthquake Early Warning Strong shaking is expected soon. Stay calm and seek shelter nearby.(Japan Meteorological Agency)”. This service is called “Area Mail Disaster Information Service” provided by docomo.
