West Java, Indonesia 1 1 People were killed by landslides. What are the causes of landslides?

Landslides are generally caused by problems in the bearing capacity of a certain part of the mountain slope, which leads to the displacement of those weak structural planes. Then there are actually two reasons for the landslide, one is caused by natural factors and the other is caused by human factors.

The natural cause of landslide may be that this landform is prone to safety accidents, and its geological structure is also problematic, and there may be groundwater below. All these may lead to the hollow image of the mountain, and may also lead to the weak bearing capacity of the slope in this area, which may eventually lead to landslides. Then human factors may be because people over-exploited when building factories or laying foundations here, or because people's blasting has an impact on the soil here.

Generally, this phenomenon only occurs when the sliding force of the mountain sliding surface is greater than the anti-sliding force, and landslides generally occur in places with soft soil and large slope, because we all know that there is a gravitational acceleration, and of course it has a certain relationship with friction. On the mountain, it refers to the anti-sliding ability, so we should pay special attention, especially when there are frequent rainstorms in this area, because the erosion of rainstorms may lead to the softening of the soil.

But fortunately, phenomena such as mudslides and landslides are actually traceable, which will give you some omens before they happen, so if we live on this slope where landslides may occur, we should observe nature more carefully, such as whether there are cracks in some rock joints, whether there are cracks in the middle and front of the hillside, and whether the original cracks have changed. At the same time, are there any new cracks in the house you live in, or are there any skew in the house, and are there any changes in the wires and circuits built on the hillside? At the same time, we should also observe whether there are changes in the daily life of animals on the hillside. For example, animals will become very anxious, keep barking there, or become extremely frightened. When something unusual happens, we should be vigilant.
