This is the city of Onihah. Due to the practice of naming a land by the same name as the city, it is presumed to also be the land of Onihah. The city of Onihah is on the Sea East shore. The land of Onihah borders the land of Mocum and is southward of the lands of Jerusalem and Mocum.

III NEPHI 4:29 [9:4]: And behold, that great city Moroni have I caused to be sunk in the depths of the sea, and the inhabitants thereof to be drowned.
Commentary: This verse references the places of Jerusalem, Mocum, Moroni, Onihah, and the Sea East. The city Moroni is close enough to the Sea East shore to be sunk into the sea. By Occam's Razor, the city of Moroni would be near the other cities that were also covered by the sea. These would be the cities of Jerusalem, Mocum, and Onihah.
III NEPHI 4:32 [9:7]: Yea, and the city of Onihah, and the inhabitants thereof, and the city of Mocum, and the inhabitants thereof, and the city of Jerusalem, and the inhabitants thereof, and waters have I caused to come up in the stead thereof,
Commentary: This verse references the places of Jerusalem, Mocum, Onihah, and the Sea East. These cities were covered by water, which means they were near the seashore. They are listed in geographic order meaning they shared borders in the order listed. Since the lands of Mormon, Antionum, and Moroni are northward of the land of Jerusalem, the cities of Mocum and Onihah would be southward of the land of Jerusalem.
