Which countries in the world have had natural disasters in recent years?

1.Hurricane Katrina hit the coasts of Louisiana and Mississippi in the United States.

Type of disaster: Hurricane.

On 23 August 2005, the United States Hurricane Center monitored the formation of a low tropical pressure No. 12 over the seas southeast of the Bahamas. On the morning of August 24, this pressure was strengthened into a tropical storm, which was named "Katrina", and as the cyclone continued to strengthen, on August 25, Katrina evolved into a hurricane, becoming the fourth hurricane of the 2005 Atlantic hurricane season. At 6:30 p.m. that night, Katrina made landfall in Haranda Beach, Florida, and swept across its southern region, after which it entered the Gulf of Mexico, where it quickly intensified into a Category 5 hurricane and rushed toward the United States at 257 kilometers per hour.

2.South Asia University**.

Location: South Asia.

Disaster Type: **.

Magnitude: Magnitude.

Since the end of 2004, the Indian Ocean has been hit by a magnitude 9**, **experts**, the geological activity of South Asian strata has become more active due to the influence of strong earthquakes, and large-scale ** will occur in South Asia in the short term. Sure enough, at 8:50:36 on October 8, 2005, there was a large-scale ** in the Kashmir region controlled by Pakistan, with an epicenter depth of 10 kilometers.

3.Iowa floods.

Disaster Type: Flood disaster.

Location: Mississippi Coast, USA.

Since June 2008, the United States has been raining for six consecutive weeks, and the water level of the Mississippi River has begun to rise sharply. Rising floodwaters overflowed homes, farms and roads along the way. After learning of the flood situation, a hospital in Iowa evacuated 176 patients to other regional hospitals from the night of the 12th to the morning of the 13th.

On the 13th, the water level of the Cedar River, a tributary of the Mississippi River, peaked in the evening, about a meter, the highest in 157 years, making it the hardest flooded place in Iowa. Floodwaters overflowed the levees and poured into the city of Cedar Rapids, flooding at least 438 homes. In addition, more than 3,000 households left their homes to seek refuge on higher ground.

Factories and cars are submerged in a sea of water.

Natural disasters happen every year in all major countries.

1. Flood disaster.

Typical areas of China: Northeast China; The middle and lower reaches of the Yellow River and the Yangtze River.

Huaihe River Basin; Pearl River Basin, etc.

Causes: (1) Natural causes: long duration of precipitation and concentrated precipitation (such as the rainy weather in the Yangtze River Basin); Changes in the intensity of the summer monsoon (subtropical high: drought in the south and flooding in the north; Vice-high and weak: flooding in the south and drought in the north); the impact of typhoons; There is a lack of natural rivers into the sea.

Dao (Huai River); low-lying terrain (Haihe River, Pearl River); There are many tributaries of the water system (fan-shaped water system, dendritic water system); river bend (Jingjiang River section); El Niro, etc. (2) Human causes: indiscriminate deforestation, resulting in aggravation of soil erosion and uplift of the riverbed; enclosing lakes to create fields; Unreasonable water conservancy project construction (Weihe.

Watershed) governance measures: afforestation and construction of shelterbelt system; returning farmland to lakes; construction of water conservancy projects; cutting bends and straightening, reinforcing the embankment; excavation into the sea channel (Huai River); construction of flood distribution areas; Establish a flood forecasting and early warning system, etc.

2. Sandstorm phenomenon.

Typical areas of China: Northwest; North China.

Causes: (1) Natural causes: the influence of fast cold front weather; The climate is arid with little precipitation; There are many windy days in spring; Sparse surface vegetation (2) Anthropogenic causes: overgrazing; excessive woodpicking; Over-reclamation.

Governance measures: formulate laws and regulations on grassland protection and strengthen management; control of livestock carrying capacity; the construction of the "Three-North Shelterbelt"; returning farmland to forests and pastures; construction of artificial grasslands; promotion of rotational grazing; It is forbidden to harvest fat cabbage, etc.

3、**。Typical areas of China: eastern coast; Southwest and Northwest regions.

Cause: It is located at the junction of the Eurasian plate, the Pacific plate and the Indian Ocean plate, and the earth's crust is vigorous.

Significant loss of life and property may be caused by large magnitude and destructiveness; There are many cities near the epicenter, and the population is concentrated; Shallow source**; It may occur at night; Induce other disasters, etc.

Disaster mitigation measures: Actively carry out publicity and education on disaster prevention and mitigation to raise public awareness of environmental protection and disaster reduction; Establish a disaster monitoring and forecasting system; strengthen the management of geological disasters, establish and improve the system of policies and regulations for disaster reduction; improve the seismic strength of buildings; afforestation and the establishment of a shelterbelt system; strengthening international cooperation, etc.

4. Southwest China.

Geological disasters are serious.

Causes: (1) Natural causes: the mountainous area is vast, the rocks are broken, and the weathering is serious; The dry and wet seasons are distinct, and the rainstorm is concentrated; The earth's crust is moving strongly, and mountain faults are developing. (2) Human causes: damage to vegetation.

Remediation measures: Restoration of vegetation.

Missing: 17,923 people.

Economic loss. as of 4 September 2008).

The direct economic loss caused by Wenchuan ** this time was 845.1 billion yuan. Sichuan was the most serious, accounting for the total losses, Gansu accounted for the total losses, and Shaanxi accounted for the total losses. The National Bureau of Statistics divides the loss indicators into three categories, the first category is the problem of personnel, the second category is the problem of property loss, and the third category is the problem of damage to the natural environment.

Among the property losses, the loss of houses is very large, and the losses of private houses and urban residents' houses account for the total losses. Including the loss of schools, hospitals and other non-residential buildings, the total loss. In addition, there are also the loss of infrastructure, roads, bridges and other urban infrastructure, accounting for the total loss, these three categories are relatively large losses, more than 70% of the losses are caused by these three aspects.

Drought, red water, mudslides. The desert area expanded.

There are mainly floods, typhoons, droughts, mudslides, frost and other natural disasters.

On March 24, in Hanoi, the capital of Vietnam, people ran to an outdoor open field after **. Myanmar's National Meteorological Service confirmed on the 24th that a level of 7 on the Richter scale occurred in the border area of northeastern Myanmar near Thailand and Laos that night**. The tremors were felt in Bangkok, the capital of Thailand, and Hanoi, the capital of Vietnam.

Xinhua Reuters.

Yangon, March 25 (Xinhua) -- Myanmar officials said on the 25th that so far, the strong ** in northeastern Myanmar on the night of the 24th has killed at least 65 people and injured 111 people, and the Thare district of Shan State has been the most severely affected.

After the incident, localities in Gyeongdong City, Tachili City and other places in Shan State, Myanmar, immediately carried out disaster relief work and organized forces to rescue the injured.

According to reports, due to the sparse population in the area closer to the epicenter, the loss of personnel and property is still being counted.

After the strong earthquake, there were many aftershocks in the local area, and the earthquake was felt strongly in Gyeongdong City, and some houses collapsed in Tachili City and nearby areas, and communication is currently intermittent.

Myanmar's National Meteorological Service confirmed on the 24th that a strong magnitude of 7 on the Richter scale occurred in the northeastern part of Myanmar near the border area of Thailand and Laos that night, with the epicenter located 56 kilometers east of Jingdong City (north latitude, east longitude).
