Overview: Which Area is Vulnerable to Landslide?

Landslide vulnerability is a measurable factor. It refers to some areas that may suffer from damage because of this disaster. The result involves some components and exposures to decide which area is vulnerable to landslide. Hence, this concept is crucial for the local authorities.

Besides physical vulnerability, social and economic impacts are the affected factors that need to be recovered from after this disaster. With accurate measurement, the government could separate some zones where the most hazardous ones might need to be emptied. Which areas are in this zone?

The Overview of Which Area is Vulnerable to Landslide

Mountainous or Hilly Areas

There are some reasons why the mountainous areas are vulnerable to landslides. The slope in this area is steep, and the material on the top can slide easily because of some factors, such as heavy rainfall and earthquakes. The steeper slope is more dangerous for any kind of building.

The area in the mountain also has extreme weather. It causes the rocks to weaken over time, so they can slide easily to the lower part. When the seismic activity exists, those rocks are loose. They can roll down and in greater amounts, causing severe landslides.

Coastal Cliffs

A coastal area has unstable geology because of natural erosion. Though this is something normal. It can trigger landslides anytime, even though there are no earthquakes or other disasters. Over time, those hit parts because of waves can collapse.

This is why the coast is part of which area is vulnerable to landslides. This fact gets worsened because of water infiltration. The rock and soil can slip because of the water content in them. Thus, the salt content in the seawater can break the surface of the cliff faster than other types of water.

Volcanic Areas

Besides the fact that volcanic areas have steep slopes, the natural force that comes during an eruption is also the cause of landslides. The materials during the eruption are out with some water or lava. More of them are lightweight and loose. Since they cannot hold together, it triggers a landslide.

Most volcanic mountains are high, so the slopes are steeper than other types of mountains. The gravity could worsen this disaster. With additional events such as heavy rainfall, the ash can absorb the water, which makes the landslides contain mudflows.

Earthquake-prone Areas

Shaking because of earthquakes can trigger landslides. The stability of the ground is loose because of the shaking, especially when the magnitude is high. The friction of soil and rock can be lower when they should hold onto the slope to create stability.

This is why earthquake-prone areas are one of which area is vulnerable to landslide. Once the aftershocks come, it can be worse because usually the landslide will happen at this time. The government should pay more attention to the fault zone and the mountainous zone.

Monsoons Areas

During monsoon, which brings heavy rainfall, an area could suffer from floods because the soil can not hold the amount of water. On the other hand, the soil becomes heavier, which makes it lose its grip. Thus, the pressure it has is higher which creates the possibility of landslides.

The area that has monsoon is usually mountainous, where the vegetation could be only herbs and short-height plantations due to deforestation. The water breaks the soil and rocks because of this matter. Soaking and drying that occur repeatedly are the reasons for the landslide triggers.

Mining Zones

Mining activity is digging the soil and the hill. Since the depth is very deep, the natural stability in the mining zone is decreased. The slopes, because of mining, are unstable and can create landslides. At the same time, the activity itself loosens the soil and rock, which leads to sliding down.

Deforested Areas

Forests are important to maintain the stability of the ground. However, deforestation could bring a nightmare because the main role of tree roots is no longer there. Water passes quickly on the surface of the ground because the soil cannot absorb and manage that creates the possibility of landslide.

Reducing the risks and damage in which area is vulnerable to landslide is the responsibility of the authorities.
