To the east of these larger islands lie a number of smaller ones. The furthest north of them, northeast of Ureparapara, is Vet Tagde (also known as Vot Tande or Vot Ganai), which is an extinct volcano that last erupted 3.5 million years ago. Other small islands in this eastern chain in the Banks Island group include the Rowa Islands (also called the Reef Islands), which are a few very small, low islands on a coral atoll. Mota Lava is the largest and highest (411 m) of this eastern chain of islands; off its southern coast, attached by high corals that can be waded through at low tide, is the tiny islet of Ra. The islands of Mota, Merig, and Merelava complete the southeastern part of the archipelago.
