Keep calm and protect yourself
There are a limited amount of things you can do during earthquake tremors. First make sure to protect yourself, and act calmly, taking into account your location at the time.
The most immediate risk to life is head injury. Cover your head with what you have near you, and quickly move to a safe place where there is no risk of falling objects. Beware of things that may topple over or collapse such as vending machines and walls, and be careful of falling objects such as glass from buildings and signboards. Also, do not stay in the same place, but evacuate to a wide open area such as a park or vacant lot.
Do not use the elevators, as there is a chance you may be trapped. If you happen to be in an elevator at the time of an earthquake, press the buttons to every floor and get off at the first floor it stops at. If you do become trapped, use the emergency interphone to call for help. People trapped in elevators are of top priority, so calmly wait to be rescued.
It can be difficult to judge whether there is an earthquake happening on a train, but if you feel something amiss, stay away from the windows and hold on to the handrails and straps. Trains will stop if tremors are detected. Even if the train stops between two stations, it is dangerous to open the doors using the emergency stop lever and exit the train without being told to do so. Follow the instructions of the train and station staff.
Move away from large, heavy objects such as display cases. Stay close to walls and large pillars and wait for the tremors to stop. Do not move about recklessly or rush to the stairs or escalators. The most dangerous risk is of a stampede happening. Make sure to follow instructions of staff members or announcements. Products and window glass may fall down, making the floor dangerous to walk on. Be careful to mind your feet so you can evacuate safely.
Do not brake suddenly. Reduce your speed slowly, pull over to the left hand side of the road, stop the car and turn off the engine. Wait until the tremors have stopped, and get information through the car radio or your mobile phone. When leaving your car to evacuate, leave the key in, keep the doors unlocked and leave a note.
