A sinkhole, at the very least. If under the ocean it could produce a tsunami or a tidal wave.
I'd probably call it a "sinkhole" instead. It may lead to a cave, but the depression itself is not a cave.
An earthquake may cause injury and loss of life, road and bridge damage, general property damage (which may or may not be covered by earthquake insurance), and collapse or destabilization (potentially leading to future collapse) of buildings. The aftermath may bring disease, lack of basic necessities, and higher insurance premiums.
Waves pounding the shoreline can make cracks. The cracks then gradually get larger and turn into a small cave. When the cave wears through the headland, an arch forms. Further erosion causes the arch to collapse, leaving the pillar of hard rock standing away from the coast-the stack. Eventually, erosion will cause the stack to collapse, leaving a stump.
In earthquakes buildings are damaged from a combination of shaking and the ground there are set into being distorted. In cases of minor damage there may be cracks in the walls and furniture and appliances may be knocked over. Interior and exterior walls typically take equal amounts of damage In cases of more severe damage a structure may partially or completely collapse. earthquakes also often disrupt underground utilities, breaking gas pipes, water mains, and underground power lines. In tornadoes buildings damage is done be very strong winds and debris carried by those winds. Minor to moderate tornado damage is almost exclusively done to the exterior of a building. Such damage includes loss of roofing material, gutters, and siding and broken windows. Stronger tornadoes may result in the removal of the roof, and possibly the collapse of some walls, with exterior walls and upper-story walls usually failing first. Very violent tornadoes can completely level most buildings, with debris blown downwind. Sometimes entire buildings can swept off their foundations. Tornadoes usually do not have significant effect underground, but utility poles are easily toppled and destroyed buildings may leave broken gas lines.
It is usually called a tornado shelter. It may be called a storm cellar if it is underground.
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.
This may be an area that has not yet been developed.

No. It is impossible for Uluru to collapse. There is more of this natural rock feature beneath the earth than there is above the surface. It is an inselberg, with a solid foundation underground which is joined to Kata Tjuta, about 35 km away. Whilst it is possible that, in the future, sections of cliff on the outer edges may collapse, this is not a sign of weakness in the inherent structure of Uluru.
Financial collapse is the primary form of collapse due to corruption.
Yes. The only known way to produce a black hole (although there may be others) is for a massive star to collapse, after it runs out of energy.
Tilly Whim Cave, located in Dorset, England, was formed through a combination of erosion and the dissolution of the surrounding limestone rock by underground water over thousands of years. The cave was likely formed by the action of waves exploiting a weakness or fissure in the limestone, gradually enlarging it to create the cave we see today. It may have also been influenced by the collapse of underlying rocks, creating the distinctive entrance and chamber.
Yes, caves are natural underground spaces. They are formed through various geological processes, such as the dissolution of limestone or the erosion of volcanic rock. Caves can vary in size and shape, and they often have unique ecosystems and geological formations inside them.
