然而由于资金不足,该系统的建设进度较为缓慢。
The system works because while earthquakes travel at the speed of sound, sensors that initially detect the shaking near the epicenter of a quake can send a message faster -- at the speed of light -- to warn residents farther away that the quake is coming.
系统的工作原理在于地震波的传播速度与声波相近,传感器在震中附近探测到震动后以光速抢先向远处的居民传递地震预警信号。
Rep. Adam Schiff (D-Burbank) said the successful test shows the need for the system.
众议员谢安达表示,这次测试的成功显示了建立系统的必要性。
While this was not the 'big one,' we need to be prepared to save lives and protect vital infrastructure -- even a few seconds of warning will allow people to seek cover, automatically slow or stop trains, pause surgeries and more," he said in a statement.
他在声明中说道,“虽然这次地震没有达到8级以上,但我们仍需做好救援准备,保护重要基础设施。即使只提前几秒预警,人们也能有更多时间寻找掩蔽物,让列车降速或停车,暂停手术和采取其他措施。”
