| | Pagan, Northern Marianas, a Close-Up Look at an Active Volcano (Site not responding. Last check: 2007-10-10) |
 | | The islands of the Marianas (which include Guam at the southernmost end), are arranged in two parallel arcs. |
 | | Closest to the trench is the inactive frontal arc, which runs north from Guam to Medinilla, and then continues underwater in a series of seamounts. |
 | | To the west runs the active volcanic arc, going from Farallon de Pajaros in the north to Anatahan in the south, where the chain passes underwater. |
