Sumatra-Andaman Disaster: 5 years later

It's been five years since an 800-mile-long (1,300 km) section of colliding plates in Earth's crust unzipped and unleashed a 9.3 megathrust earthquake from Sumatra to the Andaman Islands. The rupture moved a block of earth as long as California about 30 feet. At least 230,000 people perished from the quake and the tsunamis that followed. We're remembering the disaster, as well as looking at the many lessons and discoveries been gleaned from it -- lessons that should never be forgotten.
