A firefighter with CA-TF2 and his live-human scent working dog search debris for tsunami victims during a search and recovery mission in Ofunato, Japan on March 15, 2011. When an earthquake occurs off the coast or by a coastal region, the shifting in plates can displace the water, creating an immense wave that rages across the ocean at up to 600 miles per hour. This destructive wave is called a tsunami. (U.S. Air Force photo/Tech. Sgt. Daniel St. Pierre)
