急需 誰能幫我翻譯一下這些文章!!

Landslide, the relatively rapid downslope movements of large masses of

soil and rock debris in response to the pull of gravity. Landslides are a kind of

mass wasting, a downward movement of unconsolidated surface rocks and soils.

In general, landslides are sudden and fast, unlike creep and solifluction, which

involve gradual and slow movement.

All slides involve the failure of earth materials under shear stress (a stress

that tends to make part of a block of material slide with respect to an adjoining

part). The material can fall, slide, or flow; it may move a few feet or several

miles. Gravity provides the energy to displace the soil and bedrock, but other

factors contribute to an increase in stress and decrease in strength. An increase in

the water content of soil may reduce its cohesion and internal friction, thus

lowering its resistance to movement. To a lesser degree, the added weight of

waterlogged soil can also hasten downslope movement. The removal of lateral

support by streams, glaciers, waves, and construction or mining activities is

another factor. Construction activity may have triggered the massive landslide

that killed 70 people in the coal-mining village of Frank, Alberta, in 1903. But

natural causes were basically responsible for the increased shear stress involved.

Vibrations from blasting, heavy traffic, and earthquakes also can contribute

to shear stress and precipitate slides. An earthquake-induced slide clogged

Montana's Madison River Canyon on Aug. 17, 1959. The slide tore some 40

million cubic yards (30,000,000 cu km) of rock from the canyon wall. Moving at

an estimated speed of 100 miles (160 km) per hour, the slide buried 26 people

and formed a natural dam creating a lake 6 miles (9.7 km) long and 180 feet (55

meters) deep.
