Gov. Lolo Matalasi Moliga said the tsunami left him with lasting memories that periodically "flash through my mind."
He abandoned his car on the main road in Pago Pago village and ran for higher ground as waves hit the territorial capital that morning.
The tsunami taught lessons about the "resilience and the power of the human spirit," said Moliga, who was president of the government-owned Development Bank of American Samoa at the time.
The tsunami reawakened the people of American Samoa to the power and the ferocity of natural forces, he said.
"The series of waves which hit the territory, not only indiscriminately destroyed property, but simultaneously devastated our hearts and souls with agonizing pain and sorrow for 34 of our loved ones, who were forever swept away from this life," Moliga said.
Territorial leaders call the tsunami the "worst disaster" in American Samoa's history.
