How to predict an earthquake and can you stop it?

An earthquake also known as seismic activity is a sudden and violent shaking of the ground,and sometimes causing great destruction, as a result of movements within the earths crust or volcanic action. Earthquakes most likely happens near boundaries of tectonic plates. And tectonic plates are the two sub layers of the earths crust that move, float and even fractures and whose interaction causes earthquakes,mountains,and many more.
    Earthquakes are one of the most devastating natural disasters. But like a hurricane, tornado, volcano etc can you predict it? My answer to you all is yes you can predict a earthquake. The ways you can predict it is laser beams which can be used to detect plate movement, A seismometer that is used to pick up the vibrations in the earths crust a increase in the vibrations may indicate an earthquake, and also when radon gases escapes from cracks in the earths crust. I'm no scientists, but i think the most promising way to predict an earthquake is by measuring radon gases. i say this because once the radon gases seeps through the earth crust you can make a educated guess on where the earthquake will happen. For example, a technician at Italy's National Institute for Nuclear Physics claimed that he was able to predict the L'Aquila earthquake by measuring the radon gas seeping from the Earth's crust. 
       We can predict an earthquake but the real question is can we stop it from happening? The answer is no it is impossible to physically stop an earthquake. But with the proper structures and equipment went can lower the chance of catastrophic damage. Some companies are building safer structures, so if a earthquake was to happen the building wouldn't just collapse. We can also prepare in advance by taking preventative measures and knowing how to respond. Some things you can do during an earthquake is take cover, react safely, and many more. 
     Hence, even though we can not stop earthquakes,but we can learn more. In hopes of discovering ways to protect ourselves from them.
