Top 10 Worst Most Dangerous Earthquakes of all Time

Analysing the biggest earthquakes can be a difficult task. Below is the list of  10 Strongest earthquakes measured or approximated to have a magnitude scale or Richter magnitude scale of 8.5 and above.

10. Assam-Tibet Earthquake- Magnitude 8.6, 15 Aug 1950

70 villages vanished in the sequence of mishaps produced by an earth tremble with an epicentre in Tibetan Rima but which wrought most devastation in India’s Assam condition. Across the area, landslides stated the lifestyles of 1,526 people and delivered areas of the landscape unrecognisable from the air. The tremble was followed by serious surging, and 8 days after the first quake the natural dam on the Subansiri river burst,  Near the epicentre of the quake, witnesses described “explosive sounds” that seemed to come from rich in the air.

9.Indonesia- Northern Sumatra, Magnitude- 8.6,  March 28, 2005

One of the most devastating factors about an earthquake is that occurring near water systems, it forces the water to form tides and surf, and thus major to another damage called Tsunami. Similar factor occurred at Sumatra Islands, where an earthquake hit in the touristy month of March. Being a tropical area, the earthquake rises to Tsunami waves and traversed to areas as far as Sri Lanka. The average death due to this earthquake is approximated to be around 1500 and more than 400 people getting wounded.

8.Rat Islands Alaska earthquake 8.7 Magnitude, February 4, 1965

The Rat Islands underthrusting earthquake a 600-km part of the western end of the Aleutian Islands. This incident may have been triggered by the large displacement near the mainshock epicentre. This quake gave rise to a huge tsunami causing a loss of thousands of dollars. This tectonic setting controlled the bust behaviour of the M8.7 event.

7.Off the Coast of Ecuador- Magnitude- 8.8, January 31, 1906

It’s a very long time has passed since this disaster occurred. This earthquake was also inside the water body and rise to the Tsunami waves. These waves hit the areas of Mexico, US and even the areas of Asia giving a total death around 1500. After this Tsunami, various such coast areas started taking safety steps to stop the wounded triggered by Tsunamis.

6.Bio-Bio, Chile- Magnitude- 8.8, February 27, 2010

With extreme shaking lasting for about 3 minutes. It ranks as the sixth major earthquake ever to be recorded by a seismograph. It was felt highly in six Chilean regions. The quake caused a tsunami which ruined some coastal regions in south Chile and damaged the port at Talcahuano. It causes Casualties, 525 killed and  25 missing.

5.Kamchatka, Russia, Magnitude- 9.0, Nov. 4, 1952

The first recorded magnitude 9.0 earthquake hit off the east coastline of Kamchatka in 1952. The quake produced a 43-foot tsunami locally.  Initially assigned a magnitude of 8.2, the quake was revised to 9.0 Mw and a time of about 17 minutes, in later years. A large tsunami resulted, causing devastation and death of people around the Kamchatka Peninsula and the Kuril Islands. Hawaii was also smacked, with estimated damages around  US$1 million and livestock losses, but no human deaths were found.

4.Sendai, Japan- Magnitude- 9.0, Date- March 11, 2011

Happened just a few years in the past, this earthquake is said to be one of the most critical quakes of the record. Asia doesn’t have much area but is rich in information and technological innovation and this earthquake created Japan escape of many million brilliant minds. Despite struggling such an enormous reduction, the govt and individuals came together to reduce the impacts of this earthquake cum tsunami, and within little time bagged the headline of a superpower again!

3.Sumatra, Indonesia- Magnitude- 9.1, December 26, 2004

The quake was caused by subduction devastating tsunamis, most landmasses bordering the Indian Ocean, killing over 230,000 people in 14 countries, and inundating coastal communities with waves up to 30 meters high. It was one of the deadliest tragedy in recorded history. Sumatra was the hardest shake country, followed by Thailand, Sri Lanka and  India

The tsunami affected more deaths than other in recorded history, although some estimates say the death from the 2010 Haiti earthquake was larger. The tsunami was recorded nearly world-wide on tide indicators in the Pacific Atlantic and Indian Oceans.

2.1964 Great Alaska Earthquake- Magnitude- 9.2, March 28, 1964

It has been one of the largest earthquakes in history due to its high magnitude. The aftermath of this earthquake involved 150 people losing their lives, and a damage of hundreds of millions of dollars worth. The hits were felt some area  of New America, but the accompanying Tsunami gone to places causing such a huge amount of loss.

1.Valdivia, Southern Chile- Magnitude- 9.5, May 22, 1960

The 1960 Valdivia, Chile earthquake or The Chilean Earthquake of Sunday, 22 May 1960 is to date the most powerful earthquake ever recorded in world’s history, rating 9.5 on the magnitude scale.  the tsunami impacted southern Chile, Hawaii, the Philippines, Japan, eastern New Zealand, south-east Australia, and the Aleutian Islands in Alaska.

Around 1,655 life destroyed, 2,000,000 folks homeless  3,000  injured, and $550 million smash up in southern Chile; tsunami caused 61 deaths, 32 dead and missing in the Philippines, 138 deaths and $50 million damage in Japan, $75 million damage in Hawaii and $500,000 damage to the west coast of the America.

Summary: These attempts categorised under Devastation management definitely does help to reduce the dangers and risks that are left by the earthquake.
