A landslide (or landslip) is a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal and onshore environments. Although the action of gravity is the primary driving force for a landslide to occur, there are other contributing factors affecting the original slope stability. Typically, pre-conditional factors build up specific sub-surface conditions that make the area/slope prone to failure, whereas the actual landslide often requires a trigger before being released.
Evidence of past landslides has been detected on many bodies in the solar system, but since most observations are made by probes that only observe for a limited time and most bodies in the solar system appear to be geologically inactive not many landslides are known to have happened in recent times. Both Venus and Mars have been subject to long-term mapping by orbiting satellites, and examples of landslides have been observed on both.

Landslide in progress
Landslides in which the sliding surface is mostly deeply located below the maximum rooting depth of trees (typically to depths greater than ten meters). Deep-seated landslides usually involve deep regolith, weathered rock, and/or bedrock and include large slope failure associated with translational, rotational, or complex movement.
Landslides that occur undersea, or have impact into water, can generate tsunamis. Massive landslides can also generate megatsunamis, which are usually hundreds of metres high.

my funniest moment....

Last 2007, my father decide to buy new house as a investment in the future. So he want me and my brother to look a house at bangi area because I and my brother were study here.

At the first day we find out the new house in area bangi, all the house is so expensive. So we decide to just find with property agent but still not have a suitable house.

One day, I go out with my friend to do study group at her house. When I enter to her house area I were read the signboard "FOR SALE" at gate of my friend's neighbour. So with the high confident level, I go to that house to asking the owner about the prosedur to buy that house.

When I asking the owner that I interested to buy this house, the owner of that house said " who say I want to sale this house?? I just want to sale this gate not this house". I'm so shocked when he said like that and I just left his house after that. My friend also laugh to me and I feel so embrassed. This is the funniest moment in my life.
