What to do when there's an earthquake in Japan

Attention: The sound of EEW chime composed by NHK is not included in the video due to the copyright. You can hear the sound on the NHK website (in Japanese) - http://www.nhk.or.jp/bousai/movie/sample.html

The Earthquake Early Warning provides advance announcement of estimated seismic intensity and expected arrival time of a strong tremor before it hits your place. These estimations are based on prompt analysis of the focus and magnitude of the earthquake using wave form data observed by seismographs near the epicenter. This video helps you to picture what you should do to keep your safety when you see or hear Earthquake Early Warning at home, while driving, and at the department store.

Please note that the period between the Earthquake Early Warning and the arrival of strong tremors is very short, i.e. a matter of seconds (or between several seconds and a few tens of seconds). As a result, areas that are close to the focus of the earthquake may not receive the Earthquake Early Warning transmission before strong tremors hit.

Please also note that there are limits to the accuracy of the Earthquake Early Warning, such as the estimated seismic intensity. This is because the system is necessarily dependent on very short-term data.
