Big earthquake in Chile

A big earthquake struck off the coast of northern Chile near the town of Iquique on April 1. It had a magnitude of 8.2 on the Richter scale. The country’s army and rescue teams were sent to the area to help people. Many prisoners escaped from a jail in the area, some of whom came back on their own or were caught. The earthquake was also felt in neighboring Peru and Bolivia.

Chile gets a lot of earthquakes. The largest recorded earthquake in the world was a magnitude 9.5, also in Chile in 1960. The magnitude of an earthquake is measured on the Richter scale, and is determined by how much the earth shakes. Here is a list by the United States Geological Survey of the world’s ten largest earthquakes recorded since 1900.

Chile’s capital is Santiago, and the country is one of the world’s largest copper producers. Here is a video about earthquakes, and here is a video about copper.
