ShakeAlert’ is an earthquake early warning (EEW) system designed to warn people in advance.It does not foresee but rather detects an earthquake just as it starts and alerts that shaking is imminent.During an earthquake, energy is carried away from the hypocentre, the point where an earthquake originates underground, by two types of seismic waves: primary (P) and secondary (S) waves. The P waves are similar to sound waves and can reach about a speed of six kilometres per second. The S waves are slower, moving at a velocity of four kilometres per second. As they have larger amplitude, they cause greater damage than P waves, though.The time and place of an earthquake cannot be predicted by the EEW system since an earthquake must have begun in order for it to operate. It can only tell how many seconds you have before the strongest wave reaches where you are. To do this, it detects P waves that reach the seismometers closest to the earthquake, and sends the signal information to a computer system. Using this information, ShakeAlert first estimates the location and magnitude of the earthquake. Then, it will calculate how long it will take both P and S waves to reach your spot. Next, it notifies you of how much time is left before S waves arrive. After the alert, you will have a few seconds to ‘drop, cover, and hold on’. Unfortunately, however, you cannot receive warning if you are too close to the epicentre, the on-ground location directly above the hypocentre, because it is a blind zone.Apart from telling you to take cover, the system provides enough time to shut down electric supply lines and gas pipes; get away from dangerous chemicals or heavy machines in workplace environments; stop planes from taking off or landing; prevent cars and trains from entering tunnels or bridges; stop surgeries and; enable emergency personnel to get ready to respond. Being able to carry out such actions before the earthquake hits can help reduce the amount of damage and casualty rate. For example, the fires can be prevented by shutting down electric supply lines. By constructing buildings more resistant to earthquakes, coordinating emergency management, and educating the public, the EEW system can literally become a life-saver technology.
