Fears are mounting that the nuclear meltdown in Japan may send plumes of radioactive contamination over nearby cities and across the Pacific Ocean as the nuclear emergency worsens in the devastated country.

The Tsunami that caused the damage also hit the shores of America, Hawaii and Chile after wreaking havoc along the coastline of Japan. These video clips show the path of the Tsunami across the Pacific Ocean.
