The world’s largest earthquake with an instrumentally documented magnitude occurred on May 22, 1960 near Valdivia, in southern Chile.
It was assigned a magnitude of 9.5 by the United States Geological Survey.
It is referred to as the “Great Chilean Earthquake” and the “1960 Valdivia Earthquake.”
What are the 5 largest earthquakes ever recorded?

Has there ever been a 10.0 earthquake?
A magnitude 10.0 quake could occur if the combined 3,000 km of faults from the Japan Trench to the Kuril-Kamchatka Trench move by 60 meters, Matsuzawa said. No magnitude 10 earthquake has ever been observed. The most powerful quake ever recorded was a magnitude 9.5 temblor in Chile in 1960.
Can there be a magnitude 10 earthquake?
The San Andreas Fault is 800 miles long and only about 10-12 miles deep, so that earthquakes larger than magnitude 8.3 are extremely unlikely. The largest earthquake ever recorded by seismic instruments anywhere on the earth was a magnitude 9.5 earthquake in Chile on May 22, 1960.
What earthquake killed the most people?

What’s the highest earthquake level?
The biggest earthquake ever recorded was a magnitude 9.5. It occurred in 1960 in Chile, where the Nazca plate subducts under the South American plate. There is no theoretical limit to the magnitude of an earthquake, although it is estimated that an earthquake of magnitude 11 would split the Earth in two.
What is the strongest earthquake recorded?
The most powerful quake was the 9.5-magnitude Valdivia Earthquake that struck in Chile in 1960, according to the U.S. Geological Survey (USGS). That quake created a tsunami, which together killed an estimated 5,700 people. The 2004 Indian Ocean tsunami registered a 9.3 magnitude.
What does earthquake feel like?
A large earthquake far away will feel like a gentle bump followed several seconds later by stronger rolling shaking that may feel like sharp shaking for a little while. A small earthquake nearby will feel like a small sharp jolt followed by a few stronger sharp shakes that pass quickly.
How long does a 7.0 earthquake last?
Generally, only seconds. Strong ground shaking during a moderate to large earthquake typically lasts about 10 to 30 seconds. Readjustments in the earth cause more earthquakes (aftershocks) that can occur intermittently for weeks or months.
How far can you feel a 7.0 earthquake?
A magnitude-5.5 quake in the Eastern United States can usually be felt as far away as 300 miles (500 km), the service’s website says. The nature of the crust under eastern North America determines how far an earthquake is felt, Presgrave said.
How strong is a 7.0 earthquake?
| Magnitude | Earthquake Effects |
|---|---|
| 5.5 to 6.0 | Slight damage to buildings and other structures. |
| 6.1 to 6.9 | May cause a lot of damage in very populated areas. |
| 7.0 to 7.9 | Major earthquake. Serious damage. |
| 8.0 or greater | Great earthquake. Can totally destroy communities near the epicenter. |

Are there small earthquakes before a big one?
Many large earthquakes are preceded by smaller rumbles known as foreshocks. However, there is apparently no way to distinguish these tremors from other small quakes that don’t portend a larger temblor. At the same time, many large earthquakes do not seem to have any foreshocks.
What country has the most earthquakes?
Indonesia
What is the deadliest natural disaster in history?
The deadliest natural disaster in history is likely the Central China floods of 1931. In July and August of that year, the Yangtze River overtopped its banks as the spring melt mingled with heavy rains.
What natural disaster kills the most?
Drought and flooding are the most deadly natural phenomenon. Hurricanes, tornadoes, and earthquakes might seem like the most dangerous natural hazards you could ever face, but floods and droughts actually kill more Americans over time.
What event killed the most humans?
Wars and armed conflicts with highest estimated death tolls of 100,000 or more
| Event | Lowest estimate | Highest estimate |
|---|---|---|
| World War II | 60,000,000 | 118,357,000 |
| Three Kingdoms | 36,000,000 | 40,000,000 |
| Mongol conquests | 30,000,000 | 40,000,000 |
| European colonization of the Americas | 8,400,000 | 138,000,000 |

What is the Richter magnitude of the strongest earthquakes?
The largest recorded earthquake was the Great Chilean earthquake of May 22, 1960, which had a magnitude of 9.5 on the moment magnitude scale. The larger the magnitude, the less frequently the earthquake happens.
How long did the longest earthquake last?
With a magnitude of between 9.1 and 9.3, this earthquake is the second largest ever recorded, and it also had the longest duration, lasting between eight and 10 minutes. Devastating tsunamis hit land masses bordering the ocean, prompting a widespread humanitarian response.

What were the worst earthquakes ever?
The 1960 Valdivia earthquake (Spanish: Terremoto de Valdivia) or the Great Chilean earthquake (Gran terremoto de Chile) of 22 May is the most powerful earthquake ever recorded. Various studies have placed it at 9.4–9.6 on the moment magnitude scale.
Are there more earthquakes now?
But experts say that’s not how earthquakes work. In the past three weeks, there have been eight earthquakes that were magnitude 6.5 or greater. That’s 40 percent of the major quakes that have happened so far this year, according to the U.S. Geological Survey (USGS).
When was the first earthquake recorded?
The most widely felt earthquakes in the recorded history of North America were a series that occurred in 1811-1812 near New Madrid, Missouri. A great earthquake, whose magnitude is estimated to be about 8, occurred on the morning of December 16, 1811.
Did Atlanta just have an earthquake?
Many in Atlanta awakened by 4.4 magnitude quake Wednesday morning. However, more than three dozen earthquakes of magnitude 2.5 or greater have occurred in Georgia since 1974, according to the U.S. Geological Survey. Yet, the state doesn’t have that many quakes compared to other areas.
How far can a 4.4 earthquake be felt?
A 4.4-magnitude earthquake was reported in Tennessee early Wednesday, officials said. The quake hit about six miles north of Decatur around 4:15 a.m., according to the U.S. Geological Survey. The shaking was felt by residents as far away as Atlanta — about 149 miles south of the epicenter.
What is the fastest wave in an earthquake?
These waves are of a higher frequency than surface waves. The first kind of body wave is the P wave or primary wave. This is the fastest kind of seismic wave, and, consequently, the first to ‘arrive’ at a seismic station. The P wave can move through solid rock and fluids, like water or the liquid layers of the earth.
