What are landslides? How does it occur?
Definition and Occurrence of Landslides
Gliding is defined as the movement of a mass of rocks, debris, or earth down a slope. The USA is a “mass destruction”, which is in motion, is perceived by the soil and rock downhill under the influence of gravity. The term ‘image’ includes five different inclinations of the action: drop, incline, landslide, distribution, and rate of flow. They are then divided by the nature of the geological material (the root of the floor, the bed, or the ground). Debris flows (usually in the mudflows or landslides) and rock slides are the most common types of landslides.
It can be said that there are several reasons for every note. The slope movement occurs when the forces that act upon (mainly because of the force of gravity) are greater than the force of the ground material that makes up the slope. The reasons are the main factors that may increase the effect of downhill skiing in the forces and factors that lead up or down, and the cold of the force. Landslide-possibly initiated by you, which is carried out on the slopes, which are already available in the range, wet -, half -, car -, and health care and snow, the water level is changed, power to the erosion control, groundwater changes, earthquakes, floods, volcanic activity, disturbance by human activities, or a combination of these factors. Earthquakes and other factors can also cause landslides in the water. These earthquakes are expected to cause a landslide into the water. The USA, under the water, can sometimes cause tsunami damage, which can drastically affect the coastal zone.

A landslide is the rushing movement of soil, rock from a higher place or mountain. Landslides occur when gravitational and other forms of shear stresses within a slope exceed the shear strength of the materials that form the slope. Some other causes of landslides are heavy rainfall, erosion, poor construction practices, freezing and thawing, earthquake shaking, and volcanic eruptions. Some landslides happen slowly, and a few happen rapidly.
Heavy Rainfall:- Landslides can happen due to heavy rainfall. Rainfall can make soil wet and weak. Sometimes soil gets washed or eroded by rainfall. Therefore, the lands which become weak come down during a rush which causing landslides.
Erosion:- Erosion can cause landslides. Sometimes, due to heavy rainfall or the infertility of the soil. This type of landslide happens slowly. Lands become weak by erosion and are washed away gradually due to gravity.
Earthquake:- Earthquakes are often a big cause of the landslide. During the earthquake, everything within the land started moving. Due to some heavy weaves, the soil and rock on the land become so weak. So eventually they’re available down to gravity and cause landslides.
Volcano Erosion:- Volcano erosion is a very major cause of landslides. During the erosion, it releases molten rock, gases, which make the land weak. Magma puts out volcanic gases that sometimes release into groundwater, leading to a hot, acidic hydrothermal system that weakens rock by altering minerals to clay.
Poor construction practice: Sometimes, poor construction practice can cause landslides. Construction activities like building a railway or buildings may change the natural movement of water. When there’s heavy rainfall or a flood, water may then move to a special path, which can saturate slopes and cause landslides.
