American Samoa to get local tsunami warnings

The National Weather Service in American Samoa has been given authority to issue local tsunami warnings in some cases before official word comes from the Pacific Tsunami Warning Center in Hawaii.
Meteorologist Mase Akapo says a local warning can be issued if at least a 7.1-magnitude quake is felt by residents of the U.S. territory.
Akapo says it takes the center about 10 to 15 minutes to the gather needed information and determine if a quake generated a destructive tsunami. He says if a strong quake occurs close to the territory, that's too long.
Last Sept. 29, tsunami waves up to 46 feet (14 meters) high were generated by a magnitude 8.0 earthquake near neighboring Samoa, killing 194 people, including 34 in American Samoa.
