This article will provide you a list of Top 10 Largest Earthquakes in the world. Due to advancement in seismology and geological survey it’s quiet easy to determine magnitude of any earthquake, it was not so easy in recent past. That’s the reason you will not find any earthquake dating earlier to 19th century. It does not mean earth didn’t experience any earthquake stronger and larger than these. Geologist and scientist believe our planet has experienced earthquakes way larger than this in the past.
Earthquake magnitude is determined in Richter scale which is a logarithmic scale (in base 10). Which means an earthquake of magnitude 9 is 10 times stronger than an earthquake of magnitude 8.
Earthquakes are among those natural phenomenon which cannot be predicted hence it is so dangerous for human life. Earthquake itself does not take lives, but collapsing building, structure, landslide and Tsunami caused the damage. Earthquakes cannot be prevented,only the damage can be minimized by proper planning. See also: Top 10 Deadliest earthquakes in the world
Note: No. of Human fatality is not directly related to magnitude of earthquake. A smaller earthquake near human population can have more damage and death than these largest magnitude ones, so don’t get misguided by that.
Top 10 Largest Earthquakes in History
These largest earthquakes have caused some severe damages to human life and wealth. Smallest/weakest of these 10 earthquake is of magnitude 8.6, which is 6 times stronger than recent Nepal Earthquake (2015) which had a magnitude of 7.8 cause for the death of 3000+ (and counting) deaths. Here are the list of Top 10 Largest magnitude earthquakes.
10. Assam & Tibet earthquake
Date: 15th August, 1950
This inland earthquake is the reason for death of 780, and injured thousands. Assam earthquake is believed to have an epicenter in Tibet. A large portion of Tibet and Assam was affected by this. Landslide, and building collapse were the main reason behind the fatality.
9. Sumatra earthquake 2005, Indonesia
Date: 28th March, 2005
Sumatra faced two big earthquakes in a span of just 4 months due to geographically active plate tectonics. The second Sumatra earthquake was less violent compared to boxing day earthquake. Even though the subsequent tsunami killed 1310 in Nias island and Sri Lanka.Sumatra is the only place to face 3 of the Top 15 Largest Earthquakes in Recorded History.
8. Rat Islands earthquake, Alaska
Date: 4th February, 1965
Deaths: Not recorded
Rat island earthquake of magnitude 8.7 is the only earthquake (in recorded history) to produce tsunami 10m (32 feet) high. The tsunami and earthquake caused little damage due to its remote location. No deaths or injuries were reported for this tsunami.
7. Ecuador-Colombia Earthquake
Date: 31st January, 1906
1906 Ecuador-Colombia earthquake at the off-coast of Ecuador caused a tsunami which killed 1500 in Ecuador and Columbia. The Tsunami traveled to west coast of US, Hawaii and far Japan. Though it didn’t result in severe damage in far location due to low height.
6. Bio-bio earthquake, Chile
Date: 27th February 2010
Recent 2010 Biobio chile earthquake, subsequent aftershocks and Tsunami combined resulted at least 521 people dead, and several thousand missing. An estimated $30 Billion worth of damage was done by this earthquake. More than 800,000 people were displaced and 1.5 million people were affected by this earthquake.
5. Kamchatka earthquake, Russia
Date: 4th November,1952
Kamchatka earthquake was the very first recorded earthquake with magnitude in the scale of 9. Despite originating in nomads-land it generated Severo-Kurilsk tsunami which caused widespread damage and responsible for death of 2336 human being.
4. Tohoku Earthquake, Japan
Date: 11th March, 2011
Combined effect of 2011 Tohoku earthquake, after shocks, and Tsunami was so enormous that 15800 people lost their life. This was an undersea mega-thrust earthquake, with epicenter at 70 kilometers east of Tohoku, Japan. With a magnitude of 9.0 it is among the Top 5 Largest Earthquakes in Recorded History. Due to the earthquake Japan had to shut down some nuclear plans to avoid mishaps. economic impacts of this earthquake was huge on Japan’s economy, as this earthquake lead to power shortage.
3. Sumatra Earthquake 2004, Indonesia
Date: 26th December, 2004
2004 Sumatra boxing day earthquake is the deadliest earthquake in 21st century. The scale of the disaster caused by this earthquake is enormous. In total 227,900 people were killed and 1.7 million displaced due to the Tsunami caused by Sumatra earthquake in 14 countries. The loss is enormous because countries like India, Sri Lanka, Thailand, Indonesia are not considered as Tsunami prone zone, and due to that there was no Tsunami warning system. Epicenter of this tsunami was at a depth of 30 km in south-east of Band Aceh, Indonesia.
2. Alaskan Earthquake, Alaska
Date: 27th March, 1964
1964 Alaskan earthquake is the 2nd most powerful earthquake ever measured by seismograph in the world, and largest earthquake in continental America. Due to large inhabited area damage was limited to only 141 human life. Due to the earthquake and subsequent tsunami resulted in destruction of buildings and structures as far as Hawaii. The earthquake lasted for more than 3 minuet.
1. Valdivia Earthquake, Chile
Date: 22nd May, 1960
1960 Valdivia earthquake is the largest earthquake in recorded history. With magnitude of 9.5 Mw, it killed 1655 human lives and responsible for injury of more than 2000 people. Tsunami resulted due to this earthquake traveled the pacific ocean and affected Hawaii, Japan, the Philippines, eastern New Zealand, southeast Australia, and the Aleutian Islands in Alaska. Valdivia earthquake and resulting Tsunami left more than 2 million people homeless. This earthquake also had the largest recorded rupture zone (more than 1000 km in diameter).
