On February 17, a severe mudslide occurred in Indonesia, killing seven people and injuring many others.

On June 17, heavy rain caused floods and mudslides, and 30 million emergency funds in Sichuan Province were urgently transferred to the disaster area.

On August 19, the death toll of the Xinping mudslide in Yunnan Province rose to 33, and more than 3,000 people participated in the rescue.

On November 4, a mudslide in Yunnan killed 35 people and affected more than 1.07 million people.

At 9 a.m. on February 17, 2006, more than 500 houses and a primary school in the southern mountains of Leyte Island in the eastern Philippines were engulfed in an instant due to torrential rains in the mountains of southern Leyte. Preliminary estimates put 200 people killed and 1,500 missing in the disaster. The catastrophe in the Philippines is enough for people to pay attention to the mudslide, understand the mudslide, and prevent the mudslide while bearing the disaster.

Mudslide, as the name suggests, is mud, stones, and water, flowing together like a river. Generally, the weathering of the mountain stone in the arid area is serious, and the lack of vegetation protection, sometimes, because of the unreasonable waste mineral stacking, the mountain stone is loose, and when it encounters a particularly heavy rainstorm, the mountain stone is washed by the water, and it goes downstream. Blocking of river channels, culverts, causing river water**, breaking down dikes, flooding villages, causing serious consequences.

The conditions for the formation of debris flow are: mountainous terrain with a relatively large slope, a large amount of debris is formed on the surface due to the destruction of vegetation or the degree of weathering, and the rainfall intensity is large.

The place where the debris flow occurs is conditional, the first vegetation is seriously damaged or the vegetation coverage rate is low, located in the mountainous area, it often rains heavily in summer, and the soil is loose and easy to occur when the rainwater washes it

It can be divided into natural causes and human causes. The natural reason is that these areas are located in mountainous areas, with complex geological structures and many extreme and catastrophic weather. The human cause is human indiscriminate deforestation and unreasonable engineering construction.

Landlord,General education class homework,You're going to be very fast.,No need to ask anyone.,Look what they answered.。。 Even the Yunnan mudslide is coming...

b. Question analysis: Continuous heavy rain is the main cause of debris flow; Indiscriminate deforestation leads to serious soil erosion on the surface of the mountain, which plays a role in promoting debris flow disasters. Minor ** in the area may be the direct cause of the mudslide.

Comments: The difficulty of this question is average, and it is the key to grasp the different effects of natural causes and man-made causes on the formation of debris flows, and pay attention to comparative analysis.

On March 17, in the Huachipa district of Lima, Peru, aerial photography of the massive damage caused by floods and mudslides caused by heavy rainfall.

Affected by the "coastal El Niño phenomenon", 11 provinces across the country have experienced heavy rains in recent months, causing flash floods, river flooding, and mudslides in many places.

According to the Peruvian Meteorological Department**, the current extreme weather is likely to continue until April.

Across Peru, heavy rainfall caused river breaches, damaged 10,000 homes, collapsed 117 bridges and paralyzed countless roads.

Peru ** Kuczynski said in a statement issued on the afternoon of the 17th local time that Peru has suffered a serious climate problem, and the country has not suffered a climate disaster of this intensity since 1998.

They are all located at the junction of tectonic plates. More precisely, they are all at the junction of the first and second stages of China, and these mountains are not formed for no reason, they are the result of plate squeezing.

They are all at the junction of tectonic plates.

A: You can't outrun the speed of a mudslide.

Correct direction: Run in the direction of the mountain perpendicular to the direction of the landslide and the movement of the debris flow.

Mudslides occur in mountainous areas in many foreign countries, and like our country, they are mainly concentrated in mountainous areas.

Yes, the road from Lijiang to Zhongdian either winds along the turbulent Jinsha River or crawls in the mountain gorge. From the bridge head of Tiger Leaping Gorge Town, it enters the canyon, on one side of the road is a stream, which is estimated to be a surging flood during the rainy season, and on the other side is a steep hillside, and a lot of barbed wire has been built to block the mud and rocks that slide down the hillside.

In the rainy season, there are often some small landslides on the road, but mudslides are not very common. The road is the only land link to the outside world in the entire Shangri-La region, so it can be maintained during the rainy season.

So don't worry about that. The Tiger Leaping Gorge section is a section where you can often meet hikers and mountain bike enthusiasts. Experience the magnificence of the Jinsha River, the precipitousness of the Jade Dragon Snow Mountain and the Haba Snow Mountain, which is shocking.
