A sinkhole, at the very least. If under the ocean it could produce a tsunami or a tidal wave.
It is called weathering.
No, subsidence is typically caused by the collapse of underground materials such as soil and rock, rather than flooding caves. Flooding caves may contribute to erosion of underground materials, but it is not a direct cause of subsidence.
Yes, erosions can happen underground through processes such as underground water flow dissolving rock formations, cave formation through solution erosion, and soil erosion caused by water movement in underground aquifers. These processes may lead to the formation of caverns, tunnels, and other underground features over time.
If you stood near a shake hole, you would see a depression or pit in the ground. These holes are caused by the gradual movement or collapse of underground material, such as limestone, creating a visible cavity on the surface. They can be small or large in size, depending on the extent of the subsidence.
Excessive pressure from overlying structures can cause collapse of the cavern, leading to sinkholes or subsidence. It can also potentially lead to the rupture of the cavern roof, resulting in a cave-in or collapse. Additionally, it may trigger seismic activity within the cavern or surrounding areas.
Doline or Shakehole - the names given to the resulting depression if the collapse extends to the surface.Within the cave a collapse is often simply called that - "collapse", the result being a pile of boulders that may fill the passage completely, forming a boulder choke. (also boulder ruckle in the UK at least - possibly cavers' regional dialect.)
caldera
The word may be any of several names, such as Kevin/Kevan. The similar common term is "cave-in" -- a collapse within a cave, mine, or cavern.
A shake-hole, sink-hole or doline. The collapse may also form an entrance to the cave below, if the slumped material has not filled the passage.
It is called weathering.
There isn't a specific term for such a thing, beyond "pool"!
This may be an area that has not yet been developed.

If you were a speleologist, you would study caves and their physical, chemical, and biological features. This includes exploring cave formations, mapping cave systems, studying the underground environment, and investigating any unique life forms that may exist underground.
