Step 1
The cause of earthquakes in the west coast is intense rainfall but sometimes these are triggered by earthquakes. Landslides occur in Southern California, San Francisco Bay, parts of Northern California, and Sierra Nevada. The main hazard from landslides is destruction of residential houses. In addition, the hazard is damage to railroads, pipelines, electric lines, and roads. In Oregon, landslides occur in Coast Range, coastal Curry County, and northwestern Clackamas County. In this area there is hazard from debris flows, a fast moving, destructive landslide. The key cause of landslides is again continuous rains. In the east coast the main hazard is from tsunamis that could trigger landslides. An important hazard on the east coast is underwater landslides (a). There is a relationship between underwater landslides, earthquakes and tsunamis. Landslides occur in the mountainous regions of Ohio, Indiana, and Kentucky.

In tropical areas tropical storm triggers landslides. The hazard includes that of drowning. In addition, the hazards of tropical landslides include harm to life, property, blocking of roads, blocking of rivers leading to floods, and destruction of agriculture. In the Polar Regions, landslides cause the hazard of increasing growing season snow melt and flash floods. This leads to slope instability.

Step 2
Landslide hazard awareness program will make people in the area identify the risk factors and ask them to take action to reduce hazard from landslides.

The risk factors that make the locality susceptible to landslides is wet coastal climate, mountainous terrain and houses built along crests and bases of slopes. Steep slopes may be susceptible to slope instability. Those homes which are building where there is slope failure are susceptible to landslides. The risk ...
