The preventive measures that can be taken to avoid landslide in hilly area:

The land slide can not be prevented due to earthquakes, but land slides due to other causes can be prevented by taking the following measures:

1) By providing efficient surface and cross drainage.

2) By providing sub-surface drains at foot of the hill slope to control seepage flow.

3) By providing benching to soil slope.

4) By reducing the angle of slope or providing breast walls and retaining walls.

5) By constructing buttress at toe of hill slopes.

6) By slope treatment to minimize the erosion and to improve the stability of hill slopes. This is done by turfing, stone pitching, cement grouting etc
