A tunnel is an underground or underwater (or both) route for the transit of people and/or goods. The tunnel is surrounded by rock or other earthen materials, water or other things, and these all apply pressure on the structure of the tunnel. Sometimes these structures fail.
The failure of a tunnel can come as the result of poor engineering or construction. A "bad" design or the failure of the construction crews to follow a design can leave a tunnel vulnerable to failure. Additionally, there may be earthquakes or other natural disasters, fires or explosions in the tunnel, or other events that the tunnel was not made to withstand, and collapse is possible under the circumstances.
It generally falls under Claustrophobia. It can also be classified as Agoraphobia, which is not the fear of open spaces (as is the common misconception). Agoraphobia is defined as the fear of being in a place that is hard to get help in and escape from. Fears of lifts, tunnels and small rooms come under this. This I know because I have a fear of tunnels.
Via Canosa in Barletta building collapse happened on 1959-09-16.
Via Giotto in Foggia building collapse happened on 1999-11-11.
It has not. The ceramic industry is extremely active.
It's called an implosion.
To effectively collapse mole tunnels in your yard, you can use a garden roller or simply stomp on the tunnels to flatten them. Another method is to flood the tunnels with water to drive the moles out. Additionally, you can use traps specifically designed to catch moles.
They are liable to collapse.
Collapse earthquakes are formed when material within a geological structure collapses into underground spaces such as caves, mines, or tunnels. This sudden collapse can create seismic waves that are often localized but can be strong enough to register on seismic sensors. The collapse can be triggered by various factors, including human activities such as mining or natural processes such as erosion.
Termite tunnels on the ceiling can weaken the structure of a building and lead to potential collapse. Solutions include professional inspection and treatment to eliminate the termites, repair of damaged areas, and prevention measures such as regular maintenance and monitoring.
They were cut as tunnels into the solid rock, so they didn't need supports. Sometimes, though, they did partially collapse, as in the tomb of Hatshepsut.
they are vertical tunnels, angle tunnels, and horizontal tunnels. THE END
yes there are tunnels
Ants live underground in giant colonies. When they build tunnels, the tunnels sometimes collapse. This moves the dirt around and brings rich soil to deep parts of the ground. Ants are also part of the cycle of life. They eat other small insects and get eaten by animals such as anteaters. They also eat wood.

when they finish making the tunnels
Depends on what you mean by tunnels. There are the short tunnels that allow you to move from playground to street and vice-versa.
Not tunnels for auto traffic. There are two auto tunnels on the westbank of the Mississippi River.
