How does a landslide occur?
A landslide is caused when there is a prolonged spell of heavy rain of high intensity. The rain runs off the hillside and takes soil and vegetation with it. The hillside weakens over time and larger amounts of soil/stones and vegetation goes with it. The heavy rain penetrates /attacks the Hillside weakening it until it gives away. Landslides have impermeable rock underneath which makes the soil permeable. Gravity moves the land downhill, with rocks, pebbles and soil moving down in blocks. The aftermath of a landslide requires machinery as houses and roads can be buried underneath the rubble. It needs to clear the soil/mud and also stabilize the hill so no more collapses. A landslide can also be a result of finite stress on the slope of a hill which as a result of rain and other phenomena and sometimes the lack of tress and shubery (as these do stall the slipage) cause the land to give way.
What can occur if a forest is cut down and the soil is left bare?
new lower lying vegetation can spring up, if the soil is on an incline then erosion can occur. The extremes of erosion over a period of time could cause landslides,mudslides,etc. An ironic situation could arise if a family has logged a hillside to help build their house near where they logged,then,years later, a landslide occurred and destroyed the family's house.
Asked in Meteorology and Weather
What are Katabatic winds?
Katabatic winds, also called downslope winds or gravity winds, flow from the high elevations of mountains, hills or plateaus down their slopes to the valleys below. They occur over slopes that are cooled. Katabatic winds occur where air in contact with sloping ground is colder than air at the same level away from the hillside over the valley. They are generally nocturnal in most parts of the world when there is little cloud or no heating from the sun. They can lead to the formation of frost, mist or fog in the valleys

Asked in Natural Disasters
What factors cause natural disasters?
There are a variety of natural disasters with different factors causing them. One think is an even is often only considered a disaster if it has a major human impact. Often, though, natural disasters occur because some system or part of a system becomes unstable. An unstable hillside may give way and cause a landslide; tension between two tectonic plates may be released to cause an earthquake; An unstable air mass can release its energy in violent storms.

Asked in Criminal Law, Pyrotechnics and Fireworks
Why are fireworks illegal?
Because when you get right down to it, they are EXPLOSIVES, and are required to be handled with great care or serious injury or death could occur due to their mishandling. Most laws are passed to promote public safety and/or reduce public liability. Several locations that outlaw fireworks, yet their city hires someone to handle a 4th of July fireworks display, then it gets out of hand, and a hillside goes up in smoke. The flora and fauna are difficult at best to replace, the lives of the firefighters are endangered (for a fireworks show!) and the city gets a negative image to spend money fixing.
