Earthquake can be destructive. Unfortunately, we don’t have a reliable way to predict.
众所周知地震具有很大的破坏性。但是不幸的是,我们目前还没有任何可靠的预测方法。
But technologies can still help us under such a desperate situation. For example, sending a message after the earthquake happens, yet before it travels from underground where we live.
但是,在这种绝望的情况下,仍然有技术可以帮助我们。例如,在地震发生后,在短暂的时间内抢在地震从我们房屋的地下传播之前,发送一条提示信息给我们。

When an earthquake happens, the sensors can send electrical pulses to the control center and then ordinary people’s smartphones.
当地震发生时,传感器将电脉冲发送到控制中心,然后发送给用户的智能手机。
The signal travels at (almost) light speed and is much faster than the devastating earthquake shaking, giving local people a little bit time to prepare.
电脉冲信号几乎以光速传播,比破坏性地震的震波速度要快得多,给当地人一点准备的时间。
According to an internal document CGTN got from the project managers, the system can send messages to people less than two seconds after the earthquake happens.
根据项目经理给CGTN提供的内部文件资料,在地震发生后不到两秒,系统就可以向人们发送信息。
The system, overseen by China’s Ministry of Emergency Management, is set to be completed in 2022.
