Details for: Megata
An aerial view from the NW with Toga Bay in the foreground shows Sannomegata (center), one of a group of the three small Megata maars along the tip of the Oga Peninsula. The names of the three maars, Ichinomegata, Ninomegata, and Sannomegata mean First, Second, and Third Megata, respectively. Lakes 300-700 m wide fill the maars, which are noted localities for mantle-derived xenoliths and are located immediately east and south of Toga Bay.
