Caldera

Maug Islands are three small elongated islands up to 2.3 km long in the northern Mariana Islands. They mark the northern, western, and eastern rims of a largely submerged 2.5 km wide caldera.

The caldera has an average depth of about 200 m and contains a twin-peaked central lava dome that rises to within about 20 m of the surface.

The growth of coral on the central lava dome indicates no recent eruptions.
