20 Largest Earthquakes in the World

Nov 13,  · The most powerful earthquake ever recorded occurred on May 22, , near Valdivia, Chile in South America. It is referred to as either the Valdivia Earthquake or the Great Chilean Earthquake. On this day, the shaking began at PM local time and lasted for approximately 10 minutes, registering between a and a on the Moment Magnitude funlovestory.com: Amber Pariona. Sep 09,  · The most powerful quake was the magnitude Valdivia Earthquake that struck in Chile in , according to the U.S. Geological Survey (USGS). That quake created a Author: Becky Little.

This list gives a numerical ranking of the most powerful earthquakes that have been scientifically measured. In short, it is based on magnitude and not intensity. A large magnitude does not necessarily mean that an earthquake was deadly, or that it even had a high Mercalli intensity rating. This lower frequency is "better" at moving large structures, causing landslides and creating the ever-feared tsunami. Major oowerful are associated with every earthquake on this list. In terms of geographical distribution, only three continents are represented kost this list: Asia 3North America 2 and South America 3.

Unsurprisingly, all of these areas lie within thee Pacific Ring of Firean area where 90 percent of the world's earthquakes occur. Magnitude: 9. At UTC, the largest earthquake in recorded history occurred. The earthquake triggered a tsunami that affected most of the Pacific, earyhquake fatalities in Hawaii, Japan, and the Philippines. In Chile alone, it killed 1, people and left more than 2, homeless. The "Good Friday Earthquake" claimed the lives of people and lasted for four full minutes.

The earthquake caused destruction in the surroundingsquare kilometers including Anchorage, which how to draw harry styles cartoon heavily damaged and was felt in all of Alaska and parts of Canada and Washington.

Inwhat does the richter magnitude scale depend on earthquake struck off the western coast of northern Sumatra and devastated 14 countries in Asia and Africa.

The earthquake caused great destruction, ranking as high as IX on the Mercalli Intensity Scale MMand the ensuing tsunami caused more casualties than any other in history. Striking near the east coast of Honshu, Japanthis earthquake eathquake more than 15, people and displaced worpdIts damage totaled more than billion U.

The ensuing tsunami, which reached heights upwards of 97 feet locally, affected the entire Pacific. It was even large enough to cause an ice shelf to calve in Antarctica. The waves also damaged a nuclear power plant in Fukushima, causing a level 7 out of 7 meltdown. Earthquaks, no person was killed from this earthquake. In fact, the only casualties occurred wat than 3, miles away, when 6 cows in Hawaii died from the subsequent tsunami.

It was originally given a 8. Magnitude: 8. This earthquake killed more than people and was felt as high as IX MM. The total economic loss in Chile alone was more than 30 billion U. This earthquake occurred off the coast of Ecuador and killed betweenpeople from its ensuing tsunami. This tsunami affected the entire Pacific, reaching the shores of Japan approximately 20 hours later. This earthquake ruptured a km segment of the Aleutian Islands. It generated a tsunami around 35 feet high on a nearby island, but caused very little other damage to a state devastated a year earlier when the "Good Friday Earthquake" hit the region.

rows · Largest earthquakes by magnitude. – 2 March 27, Prince William Sound, .

Related: Humans can cause deadly earthquakes. On April 11, , at local time, a huge undersea earthquake occurred at the west of the Indonesian island of Sumatra.

Two hours later, an 8. Initially, authorities feared that the earthquake would cause a tsunami, and warnings were issued across the Indian Ocean; however, these warnings were subsequently canceled. Despite it was a huge earthquake, it occurred very remotely from an inhabited place and produced no destructive tsunami 10 cm to 0.

A child was critically injured by a falling tree. Some people used cars and motorcycles to reach higher ground and accidents occurred. Casualties: between 1, and 3, people were killed. Thousands of people injured. On August 15, , a massive earthquake occurred at Eastern Xizang-India border region, and the epicenter was located near Rima, Tibet.

It is known as the Assam-Tibet earthquake, or simply the Assam earthquake. It was destructive in both Assam a state in northeastern India known for its wildlife, archaeological sites, and tea plantations and Tibet, many buildings were destroyed and between 1, and 3, people were killed.

After the earthquake, large landslides blocked the Subansiri River. This natural dam broke 8 days later, creating a wave of 7 m 23 ft high which inundated several villages and killed people.

It was caused by two continental plates colliding — the largest known earthquake to have not been caused by an oceanic subduction. It triggered a tsunami of over 10 meters 33 feet on Shemya Island, Alaska, but thanks to its distant location, caused very little damage.

The intense shaking lasted for about three minutes. Several coastal towns in south-central Chile were devastated by the tsunami triggered by the earthquake. The tsunami also damaged the port at Talcahuano. Buildings collapsed in many cities, including the capital, Santiago, causing many deaths.

The authorities announced the final death toll of victims and 25 people missing in January On November 4, , at GMT local time a huge earthquake struck off the coast of the Kamchatka Peninsula, in the far east of Russia. It produced a great destructive Pacific-wide tsunami with waves up to 15 meters 50 feet which caused extensive damage to the Kamchatka Peninsula and the Kuril Islands, left an estimated 10, to 15, people dead. It was also very damaging in the Hawaiian Islands, but there were no human deaths attributed to the tsunami.

The waves traveled as far as Peru, Chile and New Zealand. In Alaska, the Aleutian Islands and California, tsunami waves of up to 1. On 11 March Friday, at with the local time UTC , a massive undersea megathrust earthquake notes 1 off the coast of Japan occurred.

The earthquake triggered a massive tsunami with waves up to It was one of the deadliest in human history, the waves traveled inland as far as 6 miles 10 km and caused extensive and severe structural damage in north-eastern Japan. Airports, roads and railroads destroyed, , buildings totally collapsed, , buildings half collapsed, and another , buildings partially damaged.

A dam collapsed. The tsunami also caused nuclear accidents, primarily the level 7 meltdowns means a Major accident, highest level, see notes 2 at three reactors in the Fukushima Daiichi Nuclear Power Plant complex. On 10 March , it was announced that the confirmed casualties were 15, deaths, 6, injured, and 2, people missing.

One of the deadliest natural disasters in recent history, the Sumatra Earthquake, also known as the Indian Ocean earthquake, occurred at UTC on 26 December with the epicenter off the west coast of Sumatra, Indonesia.

It ruptured the greatest fault length of any recorded earthquake, spanning a distance of km miles. The resulting tsunami, with waves up to 30 meters ft high, caused up to a quarter of a million deaths. The earthquake had also the longest duration of faulting ever observed, between 8. It caused the entire planet to vibrate as much as 1 centimeter 0. Total energy released by the quake was 4.

The vast majority of this energy was underground. This energy is equivalent to over 1, times that of the Hiroshima atomic bomb, but less than that of Tsar Bomba, the largest nuclear weapon ever detonated.

The resulting tsunami was given various names, including the Indian Ocean tsunami, South Asian tsunami, Indonesian tsunami, the Christmas tsunami there were also hundreds of thousands of Christian tourists in the areas affected by the tsunami , and the Boxing Day tsunami. It lasted approximately 4. The earthquake triggered foot 8.

Survivors out-ran the wave, climbing to high ground. It also caused a massive underwater landslide. Port Valdez city harbor and docks were collapsed, 30 people perished.

A total of people are believed to have died: 15 as a result of the earthquake itself, from the subsequent tsunami in Alaska, 5 from the tsunami in Oregon, and 13 from the tsunami in California. Also known as the Great Chilean earthquake Spanish: Gran terremoto de Chile , it was the most powerful earthquake ever recorded. The earthquake hit on May 22 in the afternoon GMT, local time , approximately miles km off the coast of Chile, parallel to the city of Valdivia.

It lasted approximately 10 minutes and triggered a massive tsunami with waves up to 25 meters 82 feet. The main tsunami severely battered the Chilean coast, and raced across the Pacific Ocean and devastated Hilo, Hawaii.

Waves as high as The death toll of Valdivia Earthquake is not certain — the total number of fatalities from the earthquake and tsunamis have been estimated between 1, and 6, About 3, people were injured. The moment magnitude scale abbreviated as MMS; denoted as Mw or M is used by seismologists to measure the size of earthquakes in terms of the energy released. The scale was developed in the s to succeed the s-era Richter magnitude scale ML.

Even though the formulae are different, the new scale retains a similar continuum of magnitude values to that defined by the older one.

As with the Richter magnitude scale, an increase of one step on this logarithmic scale corresponds to a Thus, an earthquake of Mw of 7. The magnitude is based on the seismic moment of the earthquake, which is equal to the rigidity of the Earth multiplied by the average amount of slip on the fault and the size of the area that slipped.

Since January , the MMS has been the scale used by the United States Geological Survey to calculate and report magnitudes for all modern large earthquakes. Developed in the s by seismologists Charles Francis Richter April 26, — September 30, and Beno Gutenberg June 4, — January 25, of the California Institute of Technology, the Richter magnitude scale also Richter scale assigns a magnitude number to quantify the size of an earthquake.

It is a base logarithmic scale: as measured with a seismometer, an earthquake that registers 5. The intensity of an earthquake will typically measure between 2 and 10 on the Richter scale. Any earthquakes registering below a 5. Earthquakes with a Richter rating of between 5.

It has occurred on January 12, The magnitude was 7. An estimated three million people were affected by the quake with a death toll of around , The Damghan earthquake occurred on 22 December, AD with an estimated magnitude of 7. The epicenter was close to the city of Damghan, then the capital of the Persian province of Qumis, Abbasid Caliphate now Iran. The death toll was around , with around 45, casualties in Damghan alone. In Huo county, Shanxi, every building was destroyed. In Taiyuan and Pingyang, nearly , houses collapsed.

In Tabriz itself, all major buildings, weakened by previous shocks, were ruined and all private houses, as well as the fort and walls of the city, were totally destroyed. The Aleppo earthquake occurred on 11 October Aleppo, in Northern Syria, was a large city of several tens of thousands during this period.

A contemporary chronicler in Damascus, Ibn al-Qalanisi circa — March 18, , recorded the main quake. According to him, The residents of Aleppo had been warned by the foreshocks and fled to the countryside before the main quake. Despite this, the death toll was high. The castle of Harem, where Crusaders had built a large citadel, was destroyed and the church fell in on itself.

The fort of Atharib, then occupied by Muslims, was destroyed. The citadel also collapsed, killing of the castle guard. In Aleppo, the walls of the citadel collapsed, as did the walls east and west of the citadel. Numerous houses were destroyed. It occurred on 13 December AD with an estimated magnitude of 7. A great number of people died in the Roman city of Antioch, today Antakya in Hatay province in Turkey, and surrounding areas.

Roman statesman and historian of Greek origin, Cassius Dio was there at that time. According to him, the earthquake began with a loud roaring sound, followed by intense shaking of the ground. Whole trees were thrown into the air, as were many of the inhabitants, causing great injury. Large numbers of people were killed by falling debris, while many others were trapped. The Roman Emperor Trajan 18 September 53 — 8 August AD was wintering in the city at that time, so Antioch was crowded with soldiers and many civilians that had traveled from all parts of the empire.

The emperor himself also was caught in the earthquake, as was his successor Hadrian 24 January 76 — 10 July They escaped with only slight injuries and later began a program to rebuild the city. The earthquake also triggered a local tsunami that badly damaged the harbor of Caesarea a town in north-central Israel. It struck during late May, probably between May , at mid-morning, causing severe damage to many of the buildings in Antioch and killing approximately ,, people.

It has been suggested that the very high number of casualties was a result of there being a large number of visitors in the city from the surrounding countryside, there to celebrate Ascension Day. It hit at Beijing time UTC , reportedly 7.
