About this map
The island chain geographically consists of two subgroups, a northern group of ten volcanic main islands, all are currently uninhabited; and a southern group of five coralline limestone islands (Rota, Guam, Aguijan, Tinian and Saipan), all inhabited except Aguijan. In the northern volcanic group a maximum elevation of about 2,700 feet (820 m) is reached; there are craters showing signs of activity, and earthquakes are not uncommon. Coral reefs fringe the coasts of the southern isles, which are of slight elevation.
