Death toll is expected to climb into the hundreds and many are still missing. Four tsunami waves 15 to 20 feet high hit American Samoa about 15 minutes after the quake, reaching up to a mile inland. The tsunami may have been destructive along coasts near the earthquake epicenter and could also have been a threat to more distant coasts.

About Samoa Islands
American Samoa is a group of six Polynesian islands in the South Pacific located between Hawaii and Australia. Fourteen degrees below the equator, it is the United States’ southern-most territory. It is known as the heart of Polynesia. If you drew a triangle from Hawaii, New Zealand and Tahiti you would find Samoa in the middle. Western Samoa is a neighboring independent country that shares the same culture. American Samoa became an unorganized U.S. territory in 1900.
