Most Powerful Earthquakes in History


Specialists say that the activity of the tectonic plates intensified. The effect is disastrous as devastating earthquakes occur killing hundreds of people and leaving serious damages. Despite all the precise scientific innovations, the earth is moving and man seems to be helpless in front of the most powerful earthquakes in history.

Earthquakes represent the result of the tectonic plates shifting. Sometimes, an important shifting can cause powerful earthquakes that can kill people, destroy entire cities, while the tsunamis they can trigger are able to erase islands. Here are some 5 most powerful earthquakes in history.

Valdivia, Chile (May 22, 1960) - magnitude 9.5

On May 22, 1960, an earthquake struck the coast of South Central Chile. The earthquake in Valdivia, or the Great Chilean earthquake, is the most powerful earthquake ever recorded with a magnitude of 9.5 on the moment magnitude scale. The tsunami it triggered affected the southern part of Chile, Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska. This powerful earthquake killed over 2.000 people and another 3.000 people injured, and left 2.000.000 people homeless causing damages of 550 million dollars only in the southern Chile.

The cities that most experimented the fear were Talcahuano, Arauco, Lota, Chiguayante, Cañete, and San Antonio. The earthquake generated a tsunami that caused serious damages on coastal towns in south-central Chile. It was also issued a tsunami warning in 53 countries.
