On the delta of the Mississippi River lies a city – New Orleans, which is adjacent to the Gulf of Mexico in the East and Lake Pontchartrain in the north. The crescent shaped Mississippi River flows through the city, so it is also called “new moon city”. New Orleans has a subtropical humid climate, with an average temperature of 27.7 ℃ in July and heavy rains in summer. It is a famous tourist city with beautiful scenery.

in New Orleans, most areas are below sea level, which are often hit by hurricanes. Hurricanes are not so terrible for New Orleans. However, in a long time, nature will always use its unique way to change people’s understanding several times. “Spkds”, “spkds”, “spekds”, “spkds”, “spekds”, “spkds”, “spekds”, “spkds”, “spkds”, “spekds”, “spkds”, “spkds”, “spkds”, “spkds”, “spekds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkds”, “spkd. From the end of the 19th century, New Orleans began to carry out large-scale urban construction and transformation, but still retained many French and Spanish architectural styles. The urban area is divided into the old city “French district” and the new city “American district”. Founded in 1721, Jackson Square with the bronze statue of Jackson jumping horse and waving is the center of the French district. Around it, there are many early French and Spanish buildings, such as St. Louis church with gray spire, courts, city halls, monasteries and French markets in the Spanish period. In the French district, more than 70 blocks are French style buildings. The streets are straight and narrow. Bananas and tropical trees are planted on both sides. Most residents speak French and eat French food. They retain the customs of France and Spain. This is the most exotic city in the United States, known as “Paris of the United States”. But at the end of August 2005, everything here changed their original appearance.

“Katrina” hurricane landed in New Orleans

on August 25, 2005, tropical storm “Katrina” landed in the United States. It first hit Florida in the southeast at 6:30 p.m. that day, killing 11 people and interrupting the power supply of more than 1 million households. After that, “Katrina” entered the Gulf of Mexico. Affected by the water temperature, sea breeze and high-altitude radiation at that time, it rapidly strengthened into a category 5 hurricane.

on August 26, the U.S. National Geospatial Intelligence Agency provided the Federal Emergency Administration with the location of hospitals, police stations, roads and schools in the area where the hurricane passed through, and asked them to help arrange rescue. On the 27th, the governor of Mississippi asked all residents living along the Gulf coast to evacuate quickly, but people used to hurricanes didn’t care much. Late at night on the same day, the mayor of New Orleans announced at a news conference that an unusual hurricane was hitting New Orleans. He asked all residents in the city to evacuate. On the 28th, the mayor issued a mandatory order to evacuate all people in the city, and provided 10 shelters for residents who could not evacuate.

on the afternoon of the 28th, the water level of Lake Pontchartrain began to rise, and the sea level of the Gulf of Mexico began to rise. U.S. President George W. Bush reminded residents of the area where Katrina passed to quickly go to safety. At the same time, he declared a state of emergency in Louisiana and Mississippi.

on August 29, it began to rain as soon as dawn. Hurricane “Katrina” landed on the outer coast of New Orleans along the Gulf of Mexico at a speed of more than 250 kilometers per hour. At noon, the flood dike of the Industrial Canal in the city burst in two places, and the flood poured into the streets of District 9. Late at night, the flood dike of the 17th Street Canal burst about 90 meters. The lake water of Pontchartrain Lake poured into the whole city, and 80% of the area was flooded. The power and water supply of the whole city were cut off. The leaked gas bubbled in the water, which could catch fire at any time, or even explode. The lakeside airport and expressway were soaked in the water. The whole city fell into panic. On the roofs and trees, people cried desperately for help. In the

hospital, medical staff treated each injured person with only resources with the help of the weak light generated by a generator, but sometimes someone died while waiting for treatment.

due to the high groundwater level in New Orleans, all tombs are built on the ground. Therefore, during the hurricane, people can see some coffins floating out of the damaged tombs from time to time, mixed with the bodies of people who have just been drowned and soaked in the muddy flood.

many wild crocodiles gather in the wetland waters outside New Orleans. They enter the city with the flood. Many people who survived the hurricane were bitten or even killed by crocodiles. At the same time, swimming rats and poisonous snakes also appeared in the flood, domestic garbage also floated in the water, the excreta in the sewer began to spread in the water, the detergent and bleach in residents’ homes began to mix in it, and the furniture soaked in the water for a long time began to release toxic substances, The bodies floating on the water decayed rapidly in the high temperature… The flood in New Orleans began to turn into a pot of poisonous soup.

from August 30, hungry victims began to take to the streets to grab food and drinking water everywhere. Some rogue groups also began to take advantage of the fire. At this time, the police force had to be divided into two units, which were responsible for saving people and maintaining law and order. A large number of police officers have given up their posts one after another, and two of them have committed suicide. Facing this situation, the only police are becoming more and more incompetent. The whole city has gradually fallen into anarchy and the riots have intensified.

and “super dome” are a gymnasium. Before the attack of “Katrina”, it was opened as a temporary shelter for people who could not escape. At the beginning, a total of 25000 residents gathered here. The hurricane soon destroyed the air conditioning and lighting system here, and the only remaining generator can only give the huge stadium weak light at night.

organized the evacuation of victims from the “super dome”

in the muggy environment, the bodies of the dead soon began to stink, people crowded with each other, and the air was filled with a suffocating smell. The victims can only get two bottles of bottled water a day, and there is a serious shortage of food. The rescue has not arrived yet. In the face of limited survival resources and in the special environment of dying, anxiety and despair continue to spread here. People become extremely irritable, quarrels continue, bloody fights can be seen everywhere, and riots continue to occur.

tap water has also been cut off since August 31. Some people fell down because of lack of strength, some people jumped off the roof and committed suicide because they couldn’t bear this torture, and more people died because of heatstroke. Because the stadium is mostly black, white people are very eye-catching. For the sake of safety, at night, white people use chairs to build a barrier around them. Men sit in the outer ring to guard in turn, and women sit in the middle, but many people can’t sleep all night because of fear.

rescuers began the search and rescue work.

another temporary shelter in the city – the City Convention Center, the scene was even more shocking. The indoor temperature reached 41 ℃, the bodies of the dead were placed on the second floor, and the corridor was crowded with all kinds of patients. Many of them were injured in the disaster, but what is more serious is the mental torture they are now suffering. “At first we were grateful for this shelter, but later we felt like we were in hell,” the refugees said

difficult rescue

on the afternoon of August 30, more than 24 hours after the hurricane ravaged New Orleans, the 920 rescue team of the US Air Force Reserve Command was allowed to carry out the rescue operation. 48 hours after the disaster, the first batch of national guards entered New Orleans. On the evening of September 1, the coast guard, the US Air Force and transportation forces began to mobilize in an all-round way to dispatch manpower, materials and means of transportation to the rescue.

today’s New Orleans city

violent hurricanes and floods destroyed a large number of bridges and roads. Interstate 10 from New Orleans to Houston was full of fleeing vehicles. It usually takes only two hours, but now it takes seven or eight hours. Military vehicles loaded with food and other supplies began to enter the city, and commercial aircraft and cargo aircraft came to rescue the survivors. Tens of thousands of strayed survivors waited to leave at the chaotic Armstrong International Airport. Buses were also loaded with refugees and evacuated to shelters in other states, but soon these shelters exceeded their limits.

with the entry of thousands of National Guard personnel, the public security of New Orleans has been gradually controlled, but the rescue work is not going smoothly. Although there are helicopters in charge of rescue everywhere, there is no unified command center to coordinate them. There is chaos everywhere.

after being hit by the flood, the health condition of New Orleans has become extremely poor, a major plague may break out at any time, and the leaked fuel and gas are very likely to cause an explosion. The government ordered the rescue forces to insist on the mandatory evacuation of all citizens “left behind” in the city. It was not until September 4 that the search and rescue work was temporarily completed.

terrible numbers

this terrible hurricane has the energy of about 10 megatons of nuclear bombs, causing huge damage to Louisiana, Mississippi and Alabama in the southern United States. Where the hurricane goes, houses collapse instantly and the whole wall of skyscrapers is stripped off, The subsequent floods flooded 80% of New Orleans and trapped tens of thousands of people.

in this disaster, more than 1200 people died, tens of thousands of people were missing, millions of residents were displaced, and all residents of New Orleans were transferred. The economic losses caused by the hurricane to the United States have reached a record $100 billion.

a mayor of New Orleans once said: “the spirit of New Orleans people is like the Mississippi River. They follow their nature, reshape themselves and have the courage to open up the way forward.” After the hurricane, people in New Orleans began a difficult post disaster reconstruction. Although they have experienced thousands of hardships, people have never given up their vision of a new life. Now New Orleans is becoming a prosperous city again, and becoming healthier and more vibrant.

when the encyclopedia

is in progress, the meteorological department will generally issue a forecast before the hurricane or typhoon. In order to avoid the occurrence of tragedy, we should master some necessary self rescue knowledge:
