YOGYAKARTA - Characteristics of landslide-prone areas of course need to be known as a form of vigilance against these types of natural disasters. Landslides are an event of displacement of slope-forming materials that move downwards or out of slopes.

So, what causes landslides? Check out the full review below.

Reporting from the Yogyakarta Regional Disaster Management Agency (BPBD) website, landslides are the displacement of slope-forming materials in the form of rocks, raw materials, soil, or mixed materials, which move down or out of slopes. An area is said to have great potential for landslides if there are characteristics below.

Heavy rain and dry soil are the most common causes of landslides. Below is the stage of landslides.

First, the water that absorbs into the soil will increase the weight of the soil

If the water penetrates until the ground is waterproof which functions as a sliding area, then the soil becomes slippery and the weathering soil above it will move along the slope and out of the slope

After that, the landslide occurred.

In addition to information on the characteristics of landslide-prone areas, there are several ways that can be considered to reduce landslides. Check out the following explanation.

You are not advised to build a building under a cliff because building a building under a cliff has a big threat of landslides. If the cliff is 100 meters high, it is better to keep a distance of 250 meters between the location of the house or building from the foot of the slope. If a landslide occurs, at least it will not reach the building.

Building a rice field or pond above a slope further increases the potential for landslides. This is because the surface of the slope will be full of water, so that the soil is prone to shift and cause landslides.

If a tilted land has to be used to make rice fields or fields, it is better to create a multilevel system so that it will slow down the run off (surface flow) when it rains.

Trees located around the slopes become a deterrent to landslides because the roots of these trees spread and intersect with each other. This can help the soil not easily slide because it will become a retaining ground.

The higher the distance between the cliffs and the river, the greater the chance of landslides. Erosion of the ground does not occur directly, but the soil that continues to erode around the river will run out.
