A total of 10 major disasters in world history.

In some places, especially Indonesia, which has been hit the hardest. The tsunami reached a height of 30 meters, according to World Vision, a humanitarian aid organization. Earthquake and tsunami damage is approximate. ten billion US dollars This was the third largest earthquake in the world since 1900, and the tsunami killed more people than any tsunami recorded in history. According to NOAA’s National Center for Environmental Information.

As for Thailand, that earthquake event The tsunami hit six southern Thai provinces: Phuket, Phang Nga, Ranong, Krabi, Trang, and Satun, killing 5,395 people, injuring more than 8,457, and many missing.

9. Tangshan Earthquake (1976 / 1976)

8. ANTIOCH earthquake 526/1069

Like all disasters that happened thousands of years ago. It is difficult to calculate the death toll from the Antioch earthquake. The contemporary historian John Malalas once wrote that about 250,000 people were killed when the earthquake hit the cities of the Byzantine Empire (modern day Turkey and Syria).

In May 526, Malalas claimed that this plague was caused by the wrath of God and reported that the fire destroyed everything in Antioch.

According to a 2007 report in The Medieval History Journal, the number of deaths was higher than at any other time of the year because the city was full of tourists celebrating Ascension Day. which is a Christian feast commemorating Jesus’ ascension to heaven

7. The HAIYUAN earthquake in 1920

“The Haiyuan earthquake is the largest earthquake recorded in China in the 20th century, with the highest magnitude and intensity,” said Deng Qidong, a geologist at the Chinese Academy of Sciences. He said during the 2010 seminar, an earthquake that hit Haiyuan Province in north central China on December 16, 1920, shook the neighboring provinces of Gansu and Shaanxi. According to reports, the magnitude is 7.8 on the Richter scale. But China claims it is a magnitude 8.5. There is also a discrepancy in the death toll, with the USGS reporting that the total death toll was 200,000.

But according to a study in 2010 by Chinese seismologists, the death toll can be as high as 273,400 people. (unstable, porous, very sandy sediments) form massive landslides. causing more than 30,000 deaths (according to a 2020 study published in the journal Landslides).

Cyclone Coringa made landfall in the Indian port city of Coringa on the Bay of Bengal on November 25, 1839, reaching 40 feet (12 m) in intensity, according to the Ocean Hurricane Research Division.. Atlantic meteorology and NOAA do not know the true wind speed and type of hurricanes. Like many storms before the 20th century, it caused the destruction of around 20,000 ships and around 300,000 lives.

6. Typhoon Haiphong of 1881 (THE 1881 HAIPHONG TYPHOON)

It ranks alongside Cyclone Koringa as the sixth deadliest typhoon of 1881, which hit the port city of Haiphong in northeastern Vietnam on October 8. This has killed around 300,000 people.

5. 2010 Haiti earthquake 2010/2010

The magnitude 7.0 earthquake that struck Haiti, northwest of Port-au-Prince, on January 12, 2010, was one of the three deadliest earthquakes ever. Haiti is one of the poorest countries in the Western Hemisphere and has a history of major earthquakes. This leaves Haiti at great risk of devastation and loss of life. As many as 3 million people were affected by this tragedy.

The Haitian government estimates that around 230,000 people died, but in January 2011 the official figure was revised to 316,000.

A 2010 study published in the journal Medicine, Conflict and Survival puts the number of deaths at around 160,000, while the USGS claims a lower figure. The difference in these figures reflects the difficulty of counting the deaths even in modern times. Not to mention more political squabbling than the “official” numbers.

4. Cyclone Bola 1970/1970

This tropical cyclone has hit Bangladesh. (then East Pakistan) on November 12-13, 1970. According to NOAA’s Hurricane Research Division, the storm’s maximum wind speed was measured at 130 mph (205 kph) This made the cyclone the equivalent of a Category 4 hurricane on the Saffir-Simpson Hurricane scale before landfall A 35-foot (10.6 m) storm surge hit the low-lying islands where it was located, near the Bay of Bengal causing widespread flooding

Storm surges combined with delayed evacuations resulted in massive deaths, estimated at 300,000 to 500,000. A 1971 report by the National Hurricane Center and the Pakistan Meteorological Department recognized the challenge of accurately estimating the toll. Due to the influx of seasonal workers in the rice harvesting area.

The World Meteorological Organization states that Bola is considered the deadliest tropical cyclone ever recorded. and caused approximately $86 billion in damages.

3. SHAANXI 1556/1556 earthquake

The deadliest earthquake in history hit China’s Shaanxi Province on January 23, 1556, known as “Shaanxi Province.” “Great Jiajing Earthquake” or “Great Jiajing Earthquake” after the reigning emperor The storm destroyed 621 square miles (1,000 square kilometers) of the country. According to the Science Museums of China, around 830,000 people died in the earthquake and the exact magnitude of that earthquake has been lost to history. But current geophysicists estimate the tremor to be around 8 on the Richter scale.

2. The Yellow River flooded in 1887.

The Yellow River, or Huang He in China, sits precariously above most of the surrounding area. In the late 1880s, dams were built to store water for farmland in central China. over time these dams turned to silt and the river slowly rose. When heavy rain caused the river to overflow in September 1887, these dams overflowed into the surrounding lowlands. The flooded area reached 5,000 square miles (12,949 square kilometers), according to the “Encyclopedia of Disasters: Environmental Disasters and Human Tragedies.” An estimated 900,000 to 2 million people died.

1. The Yangtze River flooded in 1931.

Heavy rain in central China in July and August 1931 caused one of the worst natural disasters in world history: the central China flood of 1931. 1931, when the Yangtze overflows its banks with spring snow mixed with over 600mm of rain in July alone. (The Yellow River and other major waterways also reached high levels.) According to the book, “The Nature of Disaster in China: The Yang River Flood of 1931 (Cambridge University Press, 2018) inundated nearly 70,000 square miles (180,000 square kilometers) of vast land and turn the Yangtze into a huge lake or ocean.

Current government figures show that the death toll is estimated at 2 million, but other agencies, including NOAA, say it could be as high as 3.7 million.

Thailand Disaster Warning System or THAI DISASTER ALERT

Although Thailand is not in a disaster zone. Therefore, it does not often face the risk of major disasters. But after the tsunami in 2004, society realized the potential loss. So the government set up an agency to alert and integrate cooperation in responding to incidents and helping people.

In addition to warning by sms, at the beginning of the year 2022, the Department of Prevention and Mitigation of Disasters (Prevention and Mitigation of Public Disasters), the Ministry of the Interior has developed an application “THAI DISASTER ALERT” to be used in warnings of an expected disaster to take place in different areas throughout Thailand for the public to download for free (Android and IOS). real time disasters.

Applying for this app is easy, just 3 steps: 1) Enter information 2) Select an area (state) to receive information 3) Open Location, where users must select the state they want to receive alerts Can 3 states be any state or set permissions for apps Access the location (Location) of the smartphone in any area as well.

“THAI DISASTER ALERT” function will warn when the province selected by the user is predicted to have a disaster. The system will immediately send a warning message to the user. in the form of a notification message on the smartphone screen together with a menu that shows images of dangerous areas (There will be a colored bar in that area) to see clearly. There is also a menu that collects the helpline numbers of various agencies as well.

What do people often not know that can help them in the event of a disaster?

One of the recommended items in the home disaster equipment list is a simple FM/AM radio that reports the weather and is powered by a simple battery or battery. Radios (and other types of portable radios) can provide life-saving information to survivors, such as emergency broadcasts, evacuation orders, shelter-in-place instructions, and much more.

Weather radio is the best choice. because it can modify the radio waves in your area which is one of the most trusted sources of emergency information.

Cell phones are great options, though. But the transmission towers can collapse and collapse.

What do most people forget about during those times?

Many people forget to focus on their most basic needs. Also known as survival priorities. Humans don’t need much to survive. The ultimate necessities are shelter, water, air, food, safety, sleep, medical care, and hygiene that will keep us alive for a long time. But these basic needs are often confused with the need to keep possessions and the need for normal comfort and entertainment.

A “need” is the only thing you need in an emergency, and a “need” has to queue when it’s their turn.
