In the case there is any unusual activity residents in Nagoya City will be notified through official announcements. These warning announcements, called keikai sengen (警戒宣言), will come in the form of sirens outside, sirens inside stores, sirens in government buildings and in train stations, official cars with speakers, television, radio, and other local media.

Sirens and Bells
A system of sirens and bells has been set up to warn people of a strong earthquake. Sirens are set to sound off for 45 seconds straight with a 15 second interval and then go off for 45 seconds again, repeating five times in a row. Bells are set to ring for 10 cycles of five rings.

Where to go (Evacuation Areas)
Generally the closest elementary school or park has been designated as an evacuation area. Be sure to ask co-workers where to evacuate in times of emergency and to find the nearest elementary school or park in your residential and business area. The Nagoya International Center has information on evacuation areas for each residential and ward area, so feel free to come and ask for more information.
　

During an Earthquake

If indoors: Take cover under a heavy piece of furniture or against an inside wall and hold on.
Stay inside, the most dangerous thing to do during the shaking of an earthquake is to try to leave the building as objects could fall on you.

If outdoors: Move into the open, away from buildings, street lights and utility wires.
Stay there until the shaking stops.

If in a moving vehicle: Stop quickly and stay in the vehicle. Move to a clear area away from buildings, trees, overpasses, or utility wires. Once shaking stops proceed with caution. Avoid bridges or ramps that may have been damaged by the quake.

Other Important things to remember

The behaviour of pets may change dramatically after an earthquake. Normally quiet and friendly animals may become aggressive. Be sure to watch animals closely and leash your dog.
Do not move seriously injured persons unless they are in immediate danger of further injury.
Only use the telephone for emergency calls.
Clean up flammable liquids immediately and leave the area if you smell gas or fumes from chemicals or if you hear a hissing sound, most likely leaking gas pipes.
Listen to a battery-operated radio or television for the latest emergency information.
