Tornadoes tend to be an end result rather than a cause of disasters. In some cases tornadoes have been known to start fires when wood and coal-burning stoves have been knocked over in olden times. Fires do occasionally start from ruptured gas lines today, but rarely spread beyond a single building.
The tornado is itself the catastrophic event. They generally not not cause other disasters. he powerful winds of tornadoes are often strong enough to destroy houses and other buildings.
A catastrophic event in the Llano Uplift region could involve a large-scale natural disaster, such as a severe earthquake or a major flooding event. These types of events can result in significant damage to infrastructure, loss of life, and disruption to the local ecosystems. The Llano Uplift is a relatively stable geological region in central Texas, but it is still susceptible to occasional catastrophic events.
No. A cyclone can produce tornadoes, but it cannot become one. They are two very different types of weather event.
Catastrophic impacts.
A tornado is a violent, rotating windstorm that occurs within a severe thunderstorm. They are generally classed separately from other types of windstorm.
None. A tornado is fairly small compared to other types of storm. While a large enough tornado could destroye a town, not tornado is large enough to destroy a country.
Not really. A tornado is a kind of whirlwind, but most whirlwinds are not tornadoes. Other types of whirlwind include dust devils, steam devils, and firewhirls.
Compared with other types of weather event yes. The chances of any given spot being hit by a tornado in a year is very low. Although the U.S. records an average of about 1200 tornadoes annually, these are spread out over a very large area and most of them are small and short lived, so they don't affect a very large area.
In most cases the storm the produces a tornado is called a supercell, though in some cases tornadoes can develop in other types of thunderstorm.
Failure of safety critical systems can be catastrophic. like a fire alarm system in a building.
Catastrophic, Intermittent and Latent
There are many types of events where candlelight services are held. Some may be disasters such as for tornado or hurricane victims. Others may be for a victim of a tragic event.
