In the early morning hours of February 27, 2010, Martina Marturana felt a slight tremor that lasted a long time. The 12-year-old lived on Robinson Crusoe Island, 325 miles off the coast of central Chile. She looked out the window and noticed the boats in the harbor moving in an unusual way, and ran to ring an alarm bell in the town square. Eight people died in her village but she is credited with saving over 600!
