Landslide Prone Uttarakhand

There are a lot of land slides prone areas in Uttarakhand. All are requested to keep themselves safe and travel accordingly as heavy rains are expected in the days to come starting today. 

 
The damage that was done by the monsoons last year has not been completely repaired and is more likely to dig further with the kind of predictions coming up for these monsoons. 
 
Here is some information that can help us be safe and keep our people safe during monsoons.
 
AREAS THAT ARE GENERALLY PRONE TO LANDSLIDES
 
On existing landslides, old or recent
On or at the base or top of slopes
In or at the base of minor drainage hollows
At the base or top of an old fill slope
At the base or top of a steep cut slope
 
AREAS THAT ARE GENERALLY SAFE FROM LANDSLIDES
 
On hard, non-jointed bedrock that has not moved in the past
On relatively flat-lying areas away from slopes and steep river banks
At the top or along the nose of ridges, set back from the tops of slopes
 
FEATURES THAT MIGHT BE NOTICED BEFORE LANDSLIDES
 
Springs, seeps, or saturated ground in areas that have not typically been wet before
New cracks or unusual bulges in the ground, street pavements or sidewalks
Soil moving away from foundations
Ancillary structures such as decks and patios tilting and/or moving relative to the main house
Tilting or cracking of concrete floors and foundations
Broken water lines and other underground utilities
Leaning telephone poles, trees, retaining walls or fences
Offset fence lines
Sunken or down-dropped road beds
Sudden decrease in creek water levels though rain is still falling or just recently stopped.
Sticking doors and windows, and visible open spaces indicating jambs and frames out of plumb
 
IF YOU LIVE NEAR STEEP HILLS
 
>> Before Intense Storms
 
Become familiar with the land around you. Learn whether landslides or debris flows have occurred in your area by contacting local officials, state geological surveys or departments of natural resources, USGS maps, and university departments of geology. Slopes where landslides or debris flows have occurred in the past are likely to experience them in the future.
Support your local government in efforts to develop and enforce land-use and building ordinances that regulate construction in areas susceptible to landslides and debris flows. Buildings should be located away from known landslides, debris flows, steep slopes, streams and rivers, intermittent-stream channels, and the mouths of mountain channels.
Watch the patterns of storm-water drainage on slopes near your home, and note especially the places were runoff water converges, increasing flow over soil-covered slopes. Watch the hillsides around your home for any signs of land movement, such as small landslides or debris flows or progressively tilting trees.
Contact your local authorities to learn about the emergency response and evacuation plans for your area, and develop your own emergency plans for your family and business.
 
>> During Intense Storms
 
Stay alert and stay awake! Many landslide and debris flow fatalities occur when people are sleeping. Listen to a radio for warnings of intense rainfall. Be aware that intense short bursts of rain may be particularly dangerous, especially after longer periods of heavy rainfall and damp weather.
Listen for any unusual sounds that might indicate moving debris, such as trees cracking or boulders knocking together. A trickle of flowing or falling mud or debris may precede larger landslides. If you are near a stream or channel, be alert for any sudden increase or decrease in water flow. Such changes may indicate landslide activity upstream, so be prepared to move quickly. Don't delay! Save yourself, not your belongings.
If you are in areas susceptible to landslides and debris flows, consider leaving if it is safe to do so. If you remain at home, move to a part of the house farthest away from the source of the landslide or debris flows, such as an upper floor, but keep an escape route open should it become necessary to leave the house.
Be especially alert when driving. Embankments along roadsides are particularly susceptible to landslides. Watch the road for collapsed pavement, mud, fallen rocks, and other indications of possible landslides or debris flows.
 
>> After Intense Storms
 
Keep looking for signs that the land is moving. Landslides can occur weeks or months after intense storms.
