Images of Taʻū Island in American Samoa.
This reference map depicts the volcanic islands of American Samoa, and specifically the Manu‘a Islands of Ofu, Olosega, and Ta‘ū. In recent days and weeks, residents of the islands have been feeling moderate earthquakes, and the Hawaiian Volcano Observatory has deployed several staff members to American Samoa to help monitor the unrest.

Earthquakes in oceanic environments can generate pressure waves that travel long distances within the ocean itself. Much like seismographs record ground shaking, this energy is recorded by submerged hydrophones measuring pressure changes in water.
