What are the most common mountain disasters in our country?

Floods, mudslides, landslides.

flash floods, mudslides, collapses, landslides, floods, etc. Flash floods: Flash floods are floods that occur in mountain streams.

Mountain floods are sudden, the water volume is concentrated, the flow rate is large, the erosion is destructive, and the water flow carries sediment and stones, which often causes local floods. Debris flow: refers to a special torrent of landslides caused by heavy rain, heavy snow or other disasters in mountainous areas or other ravines and areas with steep terrain and carrying sediment and stones.

Flash floods: Flash floods are floods that occur in mountain streams. Mountain floods are sudden, the water volume is concentrated, the flow rate is large, the erosion is destructive, and the water flow carries sediment and stones, which often causes local floods.

Debris flow: refers to a special torrent of landslides caused by heavy rain, heavy snow or other disasters in mountainous areas or other ravines and areas with steep terrain and carrying sediment and stones.

Collapse: Collapse (caving, collapse or collapse) is a geological phenomenon in which the rock and soil mass on a steep slope suddenly detached from the parent body under the action of gravity, collapses, rolls, and accumulates at the foot of the slope (or valley).

Landslide: Landslide refers to the action and phenomenon that a certain part of the rock and soil on the mountain slope moves to the bottom of the slope as a whole due to shear displacement along a certain weak structural plane (zone) under the action of gravity (including the gravity of the rock and soil itself and the dynamic and static pressure of groundwater). It is commonly known as walking the mountain, collapsing the mountain, slippery, slippery, etc.

It is one of the common geological hazards.

Flooding: Flooding refers to the phenomenon of inundation and waterlogging of low-lying areas due to heavy rain, heavy rain or continuous rainfall. Rains and floods mainly harm the growth of crops, cause crop yields to be reduced or cut off, and undermine the normal development of agricultural production and other industries.

Its impact is comprehensive, and it will also endanger the safety of people's lives and property, and affect the long-term peace and stability of the country.

The main types of geological disasters in China are: ground subsidence and land subsidence, ground fissures, desertification, soil erosion, underground fires in coalfields, water pollution, in addition, there are only salinization, immersion, seawater inflow, erosion, swamping, siltation, collapse, Xunpei landslide, debris flow, frost heave, ice melting, heat damage, etc.

1. **, also known as ground motion and ground vibration, is a natural phenomenon that produces ** waves during the rapid release of energy in the earth's crust. The squeezing and collision between plates on the earth causes cluster dislocation and rupture at the edge of the plate and within the plate, which is the main reason for the conflict.

2. Desertification is caused by drought and lack of rainfall, vegetation destruction, wind erosion, flowing water erosion, soil salinization and other factors.

Hello; The main types of geological disasters in China are: ground subsidence and land subsidence, ground fissures, desertification, soil erosion, slow fire in the underground section of coalfields, water pollution, in addition, there are salinization, chain immersion, seawater intrusion, erosion, swamping, siltation, collapse, landslide, debris flow, frost heave, ice melting, heat damage, etc. 1. **, also known as ground motion and ground vibration, is a natural phenomenon that produces ** waves during the rapid release of energy in the earth's crust.

The main reason for the squeezing and collision between the plates on the earth is the dislocation of the edge of the plate and the rupture of the plate. 2. Desertification is caused by drought and lack of rainfall, vegetation destruction, wind erosion, flowing water erosion, soil salinization and other factors.

1. Collapse refers to the geological phenomenon that the rock and soil mass on a steep slope suddenly breaks away from the parent body and collapses, rolls, and accumulates at the foot of the slope (or valley) under the action of gravity jujube suffocation;

2. Landslide refers to the geological phenomenon of slippage of the slope rock and soil along the shear failure surface of the penetration;

3. Debris flow refers to a special torrent of landslides caused by heavy rain, blizzard or other natural disasters in mountainous areas or other ravines and areas with steep terrain and carrying a large amount of sediment and stones;

4. Slope erosion refers to all erosion phenomena that occur on the slope surface;

5. The movement of the sand dune moving bench refers to the overall downwind displacement of the sand dunes. This is achieved through wind erosion on the windward slope, where a large amount of sand accumulates on the windward slope.

Common natural disasters in mountainous areas include flash floods, mudslides, collapses, landslides, etc

Therefore, the answer is: flash floods, debris flows, avalanches, and landslides
