"I'm really impressed by Japan's earthquake warning system and quick dissemination of info to the public, it probably saved a lot of lives. This video shows a regular broadcast interrupted by the earthquake warning (giving people time to take cover), then an anchor calmly reads information, and within minutes the tsunami warning was sent out in various languages."- Shaokai Fan via Facebook
Breakdown of the video (copied/pasted from the comments below the video on YouTube):
0:08 an earthquake warning appeared for 5 northern prefectures in Japan. people were advised to prepare for a strong earthquake that will come within a few seconds
0:48 it starts shaking in Tokyo (not included in the initial warning)
1:35 announcer repeats earthquake warning
2:35 footage from NHK Tokyo office
3:28 tsunami warnings in different languages
basically the video shows Japan's early warning system for earthquakes. It gives people a few seconds warning before the shaking starts. [The] announcer and crews remain[ed] on their posts and warn[ed] people. They're the true heroes. The newscaster is speaking so well in spite of this scary situation.
