What is going on with the mudslide flow of the Guizhou EMU?

The derailment of RMB in Guizhou is the first time in the history of my country's high -speed rail operations due to mudslides disaster. my country is one of the countries with particularly serious collapse and streams in the world. So how is such a terrible mudslides? Can you prevent it? What should I do if I encounter mudslides? Poisonous Geology solves the confusion for you.

At 10:30 on June 4th, trains from Guiyang to the south of Guangzhou from north to Guangzhou suffered a departure accident at the Rongjiang Station of Guiguang Line, causing the 7 and 8 cars to take off the line, causing 1 person to die. People are injured. The accident was reported to be related to mudslides. What's going on? Hello everyone, I am a poisonous director, and today we will talk about mudslides.

First of all, let's find out what mudslides are.

Mudslides is a very common geological disaster. It is inspired by water sources such as heavy rain and snow, and the special floods of water and stones in the mountains or slopes of the mountains. Its characteristics are suddenly outbreaks, "hurry up, go in a hurry", the sticky fluid pushes back and back along the steep ravine, and runs down, has strong energy and great destruction.

It can be seen that the formation of mudslides needs to meet three conditions: favorable terrain and landforms, namely steep slopes; rich debris substances, and a large amount of water concentrated in a short time.

We can be divided into mudslides, mud, and water stones based on the material composition.

Generally speaking, the cause of mudslides includes two aspects:

1. Natural factors. It is closely related to geological structure and rainfall. In the grooves with more accumulation materials such as steep terrain, folds and fractures, sediment, and stones, every time it encounters heavy rain or continuous rainfall for a long time, it is easy to form mudslides.

2. Human factors. Due to unreasonable development, such as indiscriminately cutting trees, the hillside loses vegetation protection; when building highways, railways, canals, etc., the surface of the hillside is destroyed, unreasonable quarry, mining, and stratigraphy structure will be induced and intensified. The occurrence of mudslides.

It is often accompanied by mudslides, as well as collapse and landslides, referred to as collapsed disaster.

Collapse, also known as collapse, collapse, or collapse, refers to the geological phenomenon that suddenly breaks away from the mother's body collapse, rolling, and accumulating on the slope or grooves under the action of gravity. Lirkeling refers to the phenomenon of a certain weak surface declined under the influence of natural geological effects and human activity, and the rock and soil on the slope declines under a certain weak surface under the action of gravity. It can be seen that the liquidity of mudslides is obviously different from the two.

my country is one of the countries with particularly serious collapse and streams in the world. Among them, the southwestern region of our country is a highly dangerous area where the disaster occurs in the disaster. Essence

Next, let's analyze the relationship between the accident and mudslides.

The accident happened in the Guizhou Yuezhai Tunnel in the southwestern region. The area was in the rainy season. From the screen of news reports, the mudslides or mud flow accumulated in the tunnel entrance mainly came from the mountains next to the tunnel. From the photos, from the photos It can be seen that the soil is mainly based on the soil. According to this, we speculate that the occurrence of the accident may be caused by the mudslides and the iron rails, which means that the mudslides have already occurred before, and the saying that "hitting the slump in the slump" says that the mudslides that are slumped into the mudslides "said. Some inappropriate.

Well, what should we do when we encounter mudslides ourselves?

One word: hiding.

First of all, "hide" by yourself. When you find that the flood mudslides are struck, do not run downstream in the direction of the valley. You should climb towards the hillside on both sides of the direction of the mudslides. It

Then help others to "hide". People in the upstream areas, if the signs of mudslides are found, should immediately notify the mudslides that may affect downstream villages, schools, factories, etc. in order to avoid it in time.

Finally, listen to the command "Hiding". Residents in the mudslides are not nostalgic, obey the command, and quickly evacuate the dangerous area as required.

Then before the mudslides occur, focus on "prevention", to carry out preventive monitoring, timely stopping people who may induce mudslides in a timely manner, but also carry out sloping governance and reasonable cultivation.

Of course, the mudslides are terrible, but as long as we know that its occurrence and movement characteristics, we should prevent unnecessary casualties and losses in advance. May everyone be safe and healthy ~
