01Etymology
The ancient Chamorro word for Tamuning was Apurgan or Apotgan. "Tamuning" is a Carolinian word that was given to the area where Carolinians settled after an earthquake on January 25, 1849, near Guam caused a tsunami that devastated Lamotrek and Satawal. It is possibly the name of the clan of a Carolinian chief, though the American administration relocated the Carolinians to Saipan in the early 1900s. The area was also called Maria Christina in the 19th century.
