A Shakehole or Sinkhole.
it is a sinkhole
A cavern is a large underground cave, and a sinkhole is part of the ground that has collapsed into a hole due to weight on top of it or because of the ground underneath it dissolving. A sinkhole might occur due to land being over a cavern when the cavern roof dissolves too small and the weight on top overcomes the strength of the land.
A cavern is a large underground opening formed by weathering and erosion. This process can occur in various types of rock formations, such as limestone or sandstone. Caverns often feature unique formations like stalactites and stalagmites as a result of dripping water and mineral deposits.
A large crack in the ground formed by a river is called a gorge or canyon. If it is formed by a series of earthquakes, it is called a fault line or fissure.
The large hole at the top of a volcano is called a "crater." It is formed when explosions or collapses create a depression at the summit of the volcano.

The large circular depression at the top of a volcano that forms when the roof of the magma chamber collapses is called a caldera. Calderas can be huge in size and are formed during explosive volcanic eruptions or when the magma chamber empties and the summit collapses into the void left behind.
