Landslide at Rumah Anak-Anak Yatim, Hulu Langat..

بِسْــــــــــــــــــمِ اﷲِالرَّحْمَنِ اارَّحِيم

With the name of Allah, The Most Beneficent the Most Merciful

On 21st May 2011, the whole Malaysian is being surprised by the landslide at Al-Taqwa Orphans, FELCRA Semungkis, Hulu Langat. The landslide occurred on that afternoon, at 2.30 pm. According to the coordination of that place,the orphan is located at the hillside. Because of the heavy rain a night before the incident, the landslide is easily to occur. There are 49 residents of the orphans, including the student and workers and all of them are male.

The incident was happened at 2.30pm. On that time, the residents of the Al-Taqwa Orphans was gathering in the hall for preparing for an event with FINAS at 5.00pm.

Because of the landslide occurs quickly, many residents didn't have a lot of time to rescue themselves from being the victim of the landslide. This is because, there are two landslide occurs quickly on the same time.
25 of the residents was saved from the tragedy. 20 students and 4 wardens there was buried by the landslide.
There are a lot of people who are doing their job to help the people who are involved in the landslide buried such as the Fire Bridge, Police and Jabatan Pertahanan Awam Malaysia (JPAM). All of them have succeed in  issuing the first bodies at 4.30pm,second at 5.00pm and next at 6.10pm.

Introduction of landslide

بِسْــــــــــــــــــمِ اﷲِالرَّحْمَنِ اارَّحِيم

Computer simulation of a "slump" landslide in San Mateo County, California (USA) in January 1997

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.

Cause of landslide

Landslides occur when the stability of a slope changes from a stable to an unstable condition. A change in the stability of a slope can be caused by a number of factors, acting together or alone. Natural causes of landslides include:
--  groundwater (porewater) pressure acting to destabilize the slope

·       --   Loss or absence of vertical vegetative structure, soil nutrients, and soil structure (e.g. after a wildfire)

·         -- erosion of the toe of a slope by rivers or ocean waves

·         -- weakening of a slope through saturation by snowmelt, glaciers melting, or heavy rains

·         -- earthquakes adding loads to barely stable slope

·         -- earthquake-caused liquefaction destabilizing slopes

·       --  volcanic eruptions

landslides are aggravated by human activities, Human causes include: deforestation, cultivation and construction, which destabilize the already fragile slopes

·       --  vibrations from machinery or traffic

·        --  blasting

·         -- earthwork which alters the shape of a slope, or which imposes new loads on an existing slope

·        --  in shallow soils, the removal of deep-rooted vegetation that binds colluvium to bedrock

·         -- Construction, agricultural or forestry activities (logging) which change the amount of water which infiltrates the soil.
