Haiyan super typhoon landed in the Philippines is considered one of the strongest storms with the wind speed up to 315km / hour. In the past there were many storms with strong wind record but did not cause much damage.
>>>Great storms destroy the world
In the past, although Yasi super typhoon only caused 1 person to die, it was highly appreciated than the hurricane Katrina appeared in New Orleans with winds of 280km / h in 2005, killing 2000 people.
So far there is no standard to assess the strength of a storm by the most powerful winds that are often unable to destroy.
Hurricane Isabel took from ISS International Space Station in 2003
However, to assess the strength of a storm it is often determined by the unit of pressure. A storm that causes a lower atmospheric pressure will cause more damage in the area it passes through.
"There is a correlation between pressure and wind near the eye," said Professor Kevin Walsh, a scientist at the University of Melbourne. A storm with lower pressure will draw more wind into the eye of the storm, causing more devastation.
Air pressure is measured in units of hectopascals (hPa). Air pressure when the standard on the ground is 1,013 hPa. Air pressure when the storm Yasi appeared was 930 hPa while Hurricane Katrina created a pressure of 902 hPa.
The most devastating typhoon was ever recorded in 1970 when Bhola stormed into Bangladesh in 1970, only at 966 hPa but Bhola killed about 300,000 - 500,000 people.
The 10 biggest storms recorded in world history:
Typhoon Tip appeared in 1979 near Micronesia, west of the Pacific Ocean. With a record low air pressure at 870hPa and a diameter of 2,200 km, Tip Typhoon has broken every record in scale and intensity in history. On October 12, 1979, Typhoon Tip formed on the Pacific Ocean with winds of 305km / hour but when it reached the mainland area of Honsu Island, it was only 130 km / hour. Typhoon Tip created 600 landslides in Japan, destroyed 22,000 houses and killed 86 people
Super typhoon Nora appeared in the eastern Philippines on October 1, 1973. The storm quickly increased in 4 days with wind of 298km / hour. Air pressure was then at 877 hPa, the lowest level ever recorded at that time. Super typhoon Nora landed on the island of Luzon of the Philippines 6 days later. When the storm reached southeast China on October 10, the storm was significantly weakened. Super typhoon Nora killed 18 people and caused total damage worth about $ 2 million.
Super Typhoon Yasi caused huge waves and strong winds in Cairns
Super typhoon June was recorded in 1975 with the strongest winds of 297 km / hour. Fortunately, the storm was unable to reach the mainland area and disappeared on the Pacific Ocean. Super typhoon June is also the first storm to have three concentric circles around the eye.
Ida appeared on the western Pacific Ocean on September 20, 1958. Super typhoon quickly reached wind power of 321km / h after only 3 days. However, to Japan's Honsu island area, super typhoon Ida had only winds of 129km / hour. The storm created torrential rain in southeastern Japan and destroyed two small villages. Heavy rain caused 888 deaths and 1900 landslides.
Super Typhoon Kit formed in the Pacific Ocean on June 25, 1966. The report confirmed that the storm reached winds of 313km / hour but when the wind measurement technology was still in its infancy. Super Typhoon Kit landed on Honsu Island on June 28, causing 64 people to die.
Super typhoon Rita appeared on October 15, 1978 but only achieved wind speed at level 5 after 8 days. Air pressure measured at 878hPa, less than 8 hPa compared to the pressure of the strongest storm ever recorded. Super typhoon Rita maintains this intensity within 3 days. In the process of landing in the Philippines, super typhoon Rita became weak. The exact number of deaths due to super typhoon Rita so far has not been fully statistics.
Vanessa told the island of Guam, the island is under US control in the western Pacific Ocean with a wind speed of 109km / hour. After crossing Guam, the storm continued to intensify and reach winds of 298km / hour. Super typhoon Vanessa caused a total loss of USD 1,700,000 on Guam.
Hurricane Katrina was rated as one of the heaviest costly hurricanes that ever landed in the United States but still ranked after Hurricane Wilma. Formed in the Caribbean Sea in October and moved to the southwest. Typhoon Wilma reaches 296km / hour with a pressure of 885hPa. Wilma first landed in the Cozumel island area in Mexico and continued to move deep into the mainland. Typhoon Wilma caused the most damage in Florida, Mexico and Cuba. The storm killed 62 people and caused an estimated loss of $ 29 billion.
Typhoon Wilma caused heavy damage to the United States
Super storm Joan appeared from the Western Pacific. On August 28, 1959, super typhoon Joan achieved wind power of 314km / hour. Only one day later, super typhoon Joan landed in Taiwan with winds of 298km / hour. Super typhoons move through the Formosa Strait before weakening and disintegrating in China. Super typhoon Joan caused heavy flooding, destroyed 3,308 houses and killed 14 people.
Super typhoon Irma appeared in the western Pacific Ocean but could never land on land. The strongest wind was recorded at 290km / hour on 11/11. The storm caused a strong pressure drop from 981hPa to 884hPa in just one day.
Currently, landing in our country is also considered to be one of the rare major storms in history with terrible destruction, invite you to refer to the new information about Typhoon Tem here.
