Recursive islands and lakes

Summary

A recursive island or lake, also known as a nested island or lake, is an island or a lake that lies within a lake or an island.[1] For the purposes of defining recursion, small continental land masses such as Madagascar and New Zealand count as islands, while large continental land masses do not. Islands found within lakes in these countries are often recursive islands because the lake itself is located on an island.

Until 2020,[15] Vulcan Point was an island that existed in Main Crater Lake on Volcano Island in Lake Taal on Luzon in the Philippines.[16] Main Crater Lake evaporated during the 2020 Taal Volcano eruption,[15] but the water in Taal Lake has returned and has a new island. Vulcan Point became a peninsula.[citation needed]
