Scientists predict a major earthquake in Chile's mineral rich north

On February 27, 15 years ago, a powerful 8.8 magnitude earthquake struck the southern Chilean coast near Concepcion. The quake shook the ground for 4 minutes and unleashed a tsunami which left 550 people dead.

The quake was the most deadly natural disaster to strike the country since 1960's 9.5-magnitude tremor, which was the strongest recorded ever in the world. Scientists are predicting a large earthquake to strike the mineral-rich northern part of the country.

Chile is the second largest lithium and copper producer in the world. All of Chile's lithium and its largest copper mines can be found in the country's north.

Every 10 years, there is a major event, said Felipe Leyton a seismologist from the University of Chile. He added that fault lines in certain areas of Chile cause a great deal of stress.

This allows you to see the potential of a large earthquake, which lets us say that in the short-term, in terms of seismic and geological terms we are expecting a major earthquake in northern part.

The Andes mountains run along the western border of Chile. It is a long, skinny country that stretches 4,300 km (2672 miles).

Chile is situated on the seismically-active Ring of Fire, which surrounds the Pacific Ocean. The mountains and earthquakes of Chile are the result of the collision of the Nazca tectonic plate and the South American tectonic plate along Chile's length.

Dr. Mohama Ayaz is a geospatial and geologist at the University of Santiago in Chile. He says that GPS technology allows scientists to monitor plate movements for any variations and anticipate potential seismic events.

Ayaz stated, "We can't predict exactly when they will happen but we can prepare for them." Earthquakes are the result built-up tension and this stress depends on how long it has been since the last seismic event.

Ayaz pointed out that there have not been large releases in the northern part of the nation like there were in the southern portion of the country in 2010

Ayaz stated, "We can't predict when an earthquake will occur in the North, but we are prepared to wait." (Reporting and writing by Rodrigo Gutierrez, Alexander Villegas, Editing by Sandra Maler).
