Top 5 Captivating Facts About Earthquakes

The Cities That Moved

Chile is known for being the home of some of the world’s largest earthquakes. This is because of the country’s proximity to the so-called Ring of Fire, where two of the Earth’s tectonic plates are pushing against each other.

In 2010, one particular earthquake was labeled by the science community as one of the most important earthquakes ever studied. This compliment is, of course, not for claiming the lives of 523 people and leaving 1.5 million homeless. It’s for the quake’s sheer power that shifted the entire city of Concepcion 3 meters (10 ft) to the west.

Concepcion was not the only city displaced by the quake. Other affected cities include Chilean capital Santiago, which shifted about 28 centimeters (11 in), and Buenos Aires, which still managed to move almost 4 centimeters (1.5 in) despite being 1,300 kilometers (810 mi) away.

These changes were observed by teams from four US universities, who compared GBS measurements of the area before and after the 8.8-magnitude quake.
