MUDSLIDE

Black dots on this map identify the locations
of landslides that occurred from 2003-2006
overlaid on a map of landslide risk.
The factors that cause mudslide to occur
Nature Landslides are caused by disturbances in the natural stability of a slope. They can happen after heavy rains, droughts, earthquakes or volcanic eruptions. Mudslides develop when water rapidly collects in the ground and results in a surge of water-soaked rock, earth and debris.
HumanHuman can be causes of landslide (mudslide). Clear Cutting, method of timber harvesting is hazardous because it destroys the root structure in the area. One more, mining that use explosion methods often cause other areas to have higher risk of sliding due to vibrations under the soil.

How people respond to and recover from MudslidePeople look at the conditions that produced earlier mudslides in the same area. They examine seismic activity, weather, soil unit weights and untrained shear strength of the soil from previous disasters. Moreover, they check the water table levels. This is because high accumulations of ground water can be dangerous in steep areas. They create emergency and evacuation plans for their family and business. They also listen to the radio or TV for emergency information.
How the residents of the area have adapted to their hazard-prone environmentThey have adapted to mudslides from learning whether landslides have occurred previously in their area by contacting local authorities or country of the area. They develop emergency and evacuation plans for their family and business. Moreover, they develop an emergency communication plan in case family members are separated. Contact local authorities about emergency and evacuation plans.
TYPES OF MUDSLIDES
Mudslides occur place around the world in steep areas or channels along a stream or river. Masses of water saturated rock, earth and debris in those places rapidly move down a slope.
The area where Mudslide occurs
The list of countries where mudslide occurs frequently
• Japan • China • Malaysia • Nepal • Indonesia
• Philippine • USA • Colombia • Ecuador • Peru
Damage caused by mudslide
• Death• Destroy: Homes, cars, and roads • Destroy: natures, crops and other plantations. • Nationally mudslides cause up to $2 billion in damages a year

Mudslide is the most rapid and fluid type of
downhill mass wasting, by disturbances in the
natural stability of a slope.
