1. Natural disasters are any catastrophic events caused by nature or natural processes of the earth. The severity of a disaster is measured by the number of people lost, the economic loss and the ability to rebuild. Events occurring in uninhabited areas are not considered disasters. Therefore, a flood on an uninhabited island would not be considered a disaster, but a flood in a densely populated area is called a natural disaster.
2. They are Tsunami, Earthquake and Flood
3.Yes, It does. That is the Flood in Central Vietnam in 2020 (also known as the Flood, Historical flood) is a storm, flooding throughout Central Vietnam, starting from the night of the 6th day, the dawn of the day. October 7, 2020 to early December 2020, concentrating mainly in the provinces of Nghe An, Ha Tinh, Quang Binh, Quang Tri, Thua Thien Hue of the North Central Coast, a part of the South Central Coast including Da Nang, Quang Nam. , Quang Ngai, Binh Dinh, Phu Yen and North Central Highlands. During the period of October and November, tropical low pressure circulation, monsoon, tropical cyclones formed and continuously fluctuated in the East Sea. Beginning with two low pressure waves and Typhoon Linfa in just one week, the historic Flood 2020 is complicated with many low and major storms in October such as Typhoon Nangka, Typhoon Saudel, and Molave; Then in November with typhoon Goni, typhoon Etau, typhoon Vamco, heavy rain poured into the area, causing many localities in the Central to be flooded on a large scale, in many places the floodwaters rose, separating the areas.
The first flood was from October 6 to 13, the central provinces were seriously affected from damage to infrastructure and infrastructure to damage to people and property, and adversely affected people's lives. The second flood from October 16, the central region continued to suffer the impact of a new tropical depression in the process of turning into a storm with cold air, continuously receiving heavy rains and prolonged floods. Some central regions have their water levels surpassed in 1979 and 1999, setting a new record for floods and storms. The third flood from October 25, with two hurricanes landing, especially the severe hurricane of Hurricane Molave on 28, 29 caused enormous damage. Following is the fourth flood from November 6, causing upheaval in the whole Central region, especially moving its position to the South Central region.
The flood in the Central region of 2020 is considered a new historic flood, set at alarming level IV, belongs to the category of dangerous natural disasters, huge risks of Vietnam, affecting extensive impact and damage and damage to the whole region, destroying, delaying and pushing back the socio-economy of Central Vietnam, especially in localities such as Quang Binh, Quang Tri, Thua Thien Hue, Da Nang, Quang Nam and Quang Ngai, which were not so long ago, were hot spots of the second COVID-19 pandemic in Vietnam.
4. I think the most dangerous natural disaster of all time is a hurricane. Hurricanes cause the highest total death toll, and can cause severe flooding and are extremly dangerous.
5. There are six step to preapare for a big flood:
Step 1:Elevate Electrical Components
Electrical sockets, switches and wiring should be elevated at least 12 inches above predicted flood levels. This reduces the amount of damage a flood can cause to your home, and it prevents your home from becoming a safety hazard during the recovery period.
If you have a fuel tank in your basement, be sure to anchor it. An unanchored fuel tank can cause serious damage, such as tearing the supply line and spilling oil.
Step 2: Waterproof Your Basement
Waterproofing your basement typically requires a large sum of money, but this investment pays off if you live in an area that is frequently flooded. Along with waterproofing, set up a sump pump in the basement and a battery-operated backup in case the power goes out during the flood.
Step 3: Pay Attention to Flood Alerts
You can elevate electrical components and waterproof your basement long before a flood strikes, but some preparation has to be done in the days or hours leading up to a flash flood. Pay attention to the weather, and take flood alerts seriously.
A Flood Watch will be issued when the conditions are right for flooding. This is a good time to protect furniture and important documents. Remember to take action the moment the watch is issued, though, as you'll want to start evacuating before a Flood Warning occurs.
A Flood Warning means that a flood is happening now or going to take place soon.
