It is a Strato Volcano.
Krakatoa was a volcanic island in Indonesia Java and Sumatra. The island collapsed into the sea during a cataclysmic eruption in 1883. Continued volcanic activity caused new island to form called Anak Krakatau "son of Krakatoa". The new island Anak Krakatau is currently active.
When a volcanic cone collapses it forms a caldera.
The mountain collapses into an emptied magma chamber
I actually had problems with this question on my crossword puzzle. The answer is actually a caldera. ---------------------------------- A volcanic crater would also be a correct answer.
When a large explosive volcanic eruption destroys most of the volcano, the resulting large crater is called a caldera.

Krakatoa is a volcanic island with a caldera volcano. The caldera was formed during the catastrophic eruption in 1883, which caused the island to collapse and form a large caldera. Today, Krakatoa is composed of three main volcanic cones within the caldera.
It would have to be a caldera. A caldera is a depression in the ground, so it is logical that one would contain a lake (and some do). A volcanic neck is a pillar or mountain of rock that solidified inside a volcano, and so could not form a lake.
A caldera.
When a volcano collapses, it can form a crater or caldera. A crater is a bowl-shaped depression at the top of the volcano, while a caldera is a much larger depression that can form when the center of the volcano collapses. Both features can result in a large, empty space left behind by the volcanic activity.
Caldera volcanoes form through a process that begins with a massive eruption, where magma is expelled from the magma chamber beneath the volcano. This sudden loss of pressure causes the ground above to collapse, creating a large depression known as a caldera. Over time, the caldera may fill with water or be reformed by subsequent volcanic activity, leading to the development of new volcanic features. The result is a large, often circular basin that can be several kilometers in diameter.
Volcanic islands such as the Hawaiian Islands, particularly the Big Island, feature numerous volcanic craters that can form ponds or lakes, like Crater Lake in Kilauea. Similarly, the Azores, an archipelago in the Atlantic Ocean, boast volcanic formations with lakes in their calderas, such as Lagoa das Sete Cidades. Additionally, islands like Santorini in Greece have volcanic origins and contain caldera lakes.
The rare phenomenon you're talking about is called a calderas.Caldera is the term given to large depressions associated with volcanoes that form when volcanoes explode or collapse into the earth.
