If a large earthquake were to strike Japan today, some people would receive advance notice.
如今的日本若出现地震来临的事件，部分人将能提前得到通知。
This kind of public address alert, recorded at a Tokyo university, will automatically be triggered at certain locations seconds before a big tremor is felt. In other cases, such as trains, the alert will be transmitted digitally, or by radio.
这种大众警报会在感觉到大震动的前几秒自动触发到特定的位置，并由东京大学记录。在其他情况下，如火车，警报会通过数字或广播方式发送。

这个系统的秘密在于具体剖析某一地震。地震实际上会产生两种波，第一种是以每秒7公里传播的较小的初级波；第二种波则是能造成毁坏的波，以每秒4公里的速度传播，速度较慢。

新系统就是利用这两种波之间的速度差，在地震来临之前发出警报的。日本国家网络内共有1000多个这样的地震测试仪，经过几十年的发展，现在均和计算机系统相连接，可自动触发发出警报。本周开始正式运行。

Keihin Kyuko铁路部门的Kenji Kuwashiro称他们的往返列车网络已经使用这种预警系统。 |
