Landslides usually occur in the region where there are many slopes with slopes above 45 degrees, although it is also possible that it can also occur on flat land but the chances are smaller. For this reason, ahead of the peak of the rainy season, the government has prepared disaster preparedness centers in many landslide subscription sites. The community has also been repeatedly asked to be aware of and learn the sign of a longsor land occurring.
How to avoid landslides?
To avoid landslides, we must know the ways and efforts that must be done to prevent the occurrence of landslides. Indeed, we as humans cannot stop the occurrence of disasters 100 percent, but at least by doing preventive efforts early on will reduce the risks and impacts that will be caused.
Here are ways or efforts we can do in various ways to prevent landslides:
1. Don’t Make a Pool or Rice Field on a Slope
When we will make a pond or paddy field on the slope it is very strived not to make it because it will increase the chances of landslides. With the existence of steep cliffs especially on bare land while on top of that there are also ponds and rice fields that are filled with water certainly makes hydrostatic power stronger pressing the surface of the soil so that the soil is susceptible to shifting and causing landslides.
Severe conditions will occur if all the water from the rice field or pond suddenly disappears because it has been absorbed into the soil. That is what often happens just before a disaster occurs.
2. Not Building Houses Under the Cliff
For the problem of making a house, look for a location that is still relatively safe when you want to build a house. If the location is indeed hilly, choose a location that would be safe from the total extent of the soil in the event of a landslide.
3. Don’t Cut Trees Around Slopes
If the kit will cut trees around the slope, it is certainly not appropriate to cut trees that are in slopes or cliffs. Many do not know that the more trees, the stronger and more stable a soil is because the roots of these trees spread and intersect so that they can help the soil not easily landslide because it will become a soil barrier.
4. Don’t Cut the Cliff Upright
When you want to multiply the soil in large quantities for mining or other purposes, you should not immediately cut the body of the slope upright because it will reduce the ground holding capacity against the soil above it. Because even though on the slope is still filled with trees, if the cliff body has been cut deeply, the soil at the bottom will lose its support so that it will easily cause the occurrence of landslides.
5. Not Establishing Buildings Around the River
The higher the distance between the lips of the cliff against the river, the greater the chance of landslides. The occurrence of indirect soil erosion, but the land which continues to be eroded by soil erosion will cause more soil to run out around the river. And if during the process of rain in the rainy season where the river flow is very heavy and the volume is large, it is easy to erode.
6. Make Terraces
If a sloping land is forced to be used to make rice fields or fields, it is better to make a multilevel system so that it will slowly runoff when it rains. Do not forget to set drainage so that there is no stagnant water on the slope. Thus the further the potential for landslides.
7. Perform Preventive Efforts
By checking whether there are cracks on the ground, if found, immediately close the cracks with clay so that not much water enters the cracks. In addition, maintaining the preservation of vegetation around the cliff is also one of the prevention efforts that have proven effective.
8. Providing counseling to the Community
Related to landslides and the hazards that followed. Often the cause of the destruction of the forest area around is blighted because of the felling of trees by the surrounding community who do not yet have the awareness and knowledge of the negative impacts that will occur. By providing counseling, it will open up insight and awareness from the community not to do things that can trigger a disaster.
9. There must be intervention from the government
Efforts to educate the surrounding community will be more targeted when strict regulations are made regarding violations of the rules that have been set. Therefore, there must be efforts to intervene with the government or the authorities to make strict rules and sanctions for each violation. Thus, it will reduce the risk of forest damage in the slope area.
