The Chileans brought the red, white and blue national flag with them to South Africa and have hung it on a flagpole next to their training pitch near Nelspruit, in the east of the country.
"I always pass by it after each practice session and it symbolises a little bit the suffering that our country went through during that time - the earthquake, the tsunamis, the many deaths," centre-back Waldo Ponce said.
"It's an extra motivation for us when we walk out on the pitch. We're trying to bring a little happiness to all those people who suffered so much during the earthquake. The flag is a symbol of what happened in our country."
Chile's captain and keeper Claudio Bravo said the earthquake "is on our minds. It's a very, very important thing for us."
