We will soon mark the 5th anniversary of the Indian Ocean Tsunami.

We teamed up with Reuters to introduce you to 4 people whose lives were forever changed by the events on December 26, 2004.

One person featured, Dina Astita, volunteered for the American Red Cross after losing her three sons in the tsunami. She helped children and their parents overcome the emotional trauma caused by so much death and devastation. Today, she works for the Indonesian Red Cross in Calang and has started her family again with the birth of a new son.
