what are signs and warnings of landslides?

Question

for planning of disaster management

Answer 1

Excessive rain would be one clue

Answer 2

Major landslides are usually accompanied by a faint rumbling sound that increases in volume as the landslide approaches. Also, the ground will pitch in one direction only and may begin shifting in that direction under your feet.
Recognition and avoidance of existing landslide deposits and potential slide areas is the best means of prevention. Unstable areas may sometimes be identified by trees or telephone poles tilted at odd angles, or by curved tree trunks. Other signs to look for are unnatural benches or bowl shaped depressions on otherwise uniformly sloping hillsides, indicators of surface water accumulation such as springs or water loving plants, and cracks in the ground.

Become familiar with the land around you. Learn whether landslides and debris flows
have occurred in your area by contacting local officials, state geological surveys, soil
conservation officials. The following areas are more likely to experience landslides or
mudflows:
Ø Areas where wildfires or human modification of the land have destroyed
vegetation
Ø Areas where landslides have occurred before
Ø Steep slopes and areas at the bottom of slopes or canyons
Ø Slopes that have been altered for construction of buildings and roads
Ø Channels along a stream or river
Ø Areas where surface runoff is directed
· Watch the patterns of storm-water drainage on slopes near your home, especially
places where 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. Watching small changes
could alert you to the potential of a greater landslide threat.
· Plant ground cover on slopes and build retaining walls, channels, or deflection walls
to direct the flow around buildings.

Answer 3

Cracks forming in the earth near the top of a slope.

A long-term warning sign is people building expensive houses near a steep slope. Sort of like the long term warning for an approaching tornado is a trailer park.

Answer 4

movement and excessive rain local knowledge such as in Abervan.
