Landslide

A landslide is a type of mass movement of earth caused by the instability of a slope. 
These movements are produced by different types of causes. To overcome the shear strength of a material over an area of weakness or through a narrow band of less resistant material than the rest.

Landslides on slopes are a common injury of the crust, and are usually associated with heavy rainfall. Sometimes occur in adverse or unusual geological formations, and because of excavations.

Landslides and mass movements are not the same in all cases, and in order to avoid them is essential to know the causes and how they originate. Here are some of the most common: 

• Fall
• Rops
• Slide
• Earth Flow
• Mud Flow
• Creep

1. How to prevent landslide?

• Do not be swayed by promises and illusory easy to get a lot or a house will probably want to sell in an area susceptible to creep.
• Do not cut in the mountains unless you are absolutely sure of the resistance
• Do not allow water to seep inside the mountain
• Do not allow the use of explosives in areas prone to landslides.
•  If you observe a principle of sliding notify the Local Emergency Committee, at City Hall.
• If you live in an area of high slope are sure that your home and your neighbors are tightly constructed to prevent them from falling on top of each other.

1. How to act when a landslide?

•  Agree with your family a safe place to evacuate, preferably the residence of a relative or friend.
•  It should be available whistles to warn of danger, or for help if trapped.
•  If you have a few seconds, take advantage and proceed to the evacuation.
•  If you can help older children.

1. What to do after a landslide?

• If you can assist in the rescue effort.
• Do not use public services such as transportation, telephones, hospitals, etc.
• Be very careful if you light a fire.
• Be careful when walking on the debris.

1. LAST EVENT IN COLOMBIA: 

On the road between Santa Fe-Dabeiba, as it passes through Cañasgordas, slippage occurred Monday afternoon, when a volume of 100,000 cubic meters of land and a width of about 50 meters down the hillside slid, dragging to the 30 people who were crossing at the time the sliding area and the two buses which were to continue the journey.
