In which mountains were there earthquakes? The strongest earthquake

Over its many-thousand-year history, humanity has experienced earthquakes that, in their destructiveness, can be classified as catastrophes on a universal scale. The causes of earthquakes are not fully understood and no one can say with certainty why they occur, where the next catastrophe will be and of what magnitude.

In this article we have collected the strongest earthquakes in human history, measured by magnitude. What you need to know about this value is that it takes into account the amount of energy released during an earthquake and is distributed from 1 to 9.5.

8.2 points

Although the magnitude of the 1976 Tien Shan earthquake was only 8.2, it can rightfully be considered one of the most destructive earthquakes in human history. According to the official version, this terrible incident claimed the lives of more than 250 thousand people, but according to the unofficial version, the number of deaths is close to 700 thousand and is completely justified, because 5.6 million houses were completely destroyed. The event formed the basis of the film "Catastrophe", directed by Feng Xiaogang.

Earthquake in Portugal in 1755 8.8 points

The earthquake that occurred in Portugal back in 1755 on All Saints' Day belongs to one and h the most powerful and tragic disasters in human history. Just imagine that in just 5 minutes Lisbon was turned into ruins, and almost a hundred thousand people died! But the victims of the earthquake did not end there. The disaster caused a huge fire and tsunami that raged along the coast of Portugal. Overall, the earthquake provoked internal unrest, which led to changes in the country's foreign policy. This disaster marked the beginning of seismology. The magnitude of the earthquake is estimated at 8.8.

9 points

Another devastating earthquake in Chile occurred in 2010. One of the most destructive and largest earthquakes in human history over the past 50 years has caused maximum damage: thousands of victims, millions of people homeless, dozens of destroyed settlements and cities. The greatest damage occurred in the Chilean regions of Bio-Bio and Maule. This disaster is significant in that the destruction occurred not only because of, but also the earthquake itself caused considerable harm, because its epicenter was on the mainland.

Earthquake in North America in 1700 9 points

In 1700, severe seismic activity in North America altered the coastline. The disaster occurred in the Cascade Mountains, on the border of the United States and Canada and, according to various estimates, was at least 9 points in magnitude. Little is known about the victims of one of the strongest earthquakes in world history. As a result of the disaster, a huge tsunami wave reached the shores of Japan, the destruction of which is mentioned in Japanese literature.

2011 East Coast Japan earthquake 9 points

Just a few years ago, in 2011, the eastern coast of Japan was shaken by the most powerful earthquake in human history. In 6 minutes of a magnitude 9 disaster, more than 100 km of seabed was raised 8 meters in height, and the ensuing tsunami hit the northern islands of Japan. The notorious Fukushima nuclear power plant was partially damaged, which triggered a radioactive release, the consequences of which are still felt today. The number of victims is said to be 15 thousand, but the true numbers are not known.

9 points

It is difficult to surprise residents of Kazakhstan and Kyrgyzstan with tremors - these regions are located in a fault zone of the earth's crust. But the most powerful earthquake in the history of Kazakhstan and all of humanity happened in 1911, when the city of Almaty was almost completely destroyed. The disaster was called the Kemin earthquake, which is recognized as one of the most powerful inland earthquakes of the 20th century. The epicenter of events occurred in the valley of the Bolshoy Kemin River. Huge relief gaps with a total length of 200 km formed in this area. In some places, entire houses that fell into the disaster zone are buried in these gaps.

9 points

Kamchatka and the Kuril Islands are seismically active regions and earthquakes do not surprise them. However, residents still remember the disaster of 1952. One of the most destructive earthquakes that humanity remembers began on November 4 in the Pacific Ocean, 130 km from the coast. Terrible destruction was caused by the tsunami that formed after the earthquake. Three huge waves, the height of the largest reaching 20 meters, completely destroyed Severo-Kurilsk and damaged many settlements. The waves came at intervals of an hour. Residents knew about the first wave and waited out it on the hills, after which they went down to their villages. The second wave, the largest, which no one expected, caused the greatest damage and claimed the lives of more than 2 thousand people.

9.3 points

On Good Friday, March 27, 1964, all 47 US states trembled from the Alaska earthquake. The epicenter of the disaster occurred in the Gulf of Alaska, where the Pacific and North American plates meet. One of the most powerful natural disasters in human memory, with a magnitude of 9.3, claimed relatively few lives - 9 people died out of 130 victims in Alaska and another 23 lives were claimed by the tsunami that followed the tremors. Of the cities, Anchorage, located 120 kilometers from the epicenter of events, was severely damaged. However, destruction swept along the coastline from Japan to California.

9.3 points

Just 11 years ago, one of the most, perhaps, the strongest recent earthquakes in human history occurred in the Indian Ocean. At the very end of 2004, a magnitude 9.3 earthquake several kilometers off the coast of the Indonesian city of Sumatra triggered the formation of a monstrous tsunami that wiped out part of the city from the face of the earth. 15-meter waves caused damage to cities in Sri Lanka, Thailand, South Africa and southern India. No one gives the exact number of victims, but estimates suggest that between 200 and 300 thousand people died, and several million more people were left homeless.

9.5 points

The most powerful earthquake in human history occurred in 1960 in Chile. According to expert estimates, it had a maximum magnitude of 9.5 points. The disaster began in the small town of Valdivia. As a result of the earthquake, a tsunami was formed in the Pacific Ocean, its 10-meter waves raged along the coast, causing damage to settlements located near the sea. The scope of the tsunami reached such proportions that its destructive force was felt by residents of the Hawaiian city of Hilo, 10 thousand kilometers from Valdivia. Giant waves even reached the shores of Japan and the Philippines.

It seems that natural disasters happen once every hundred years, and our vacation in one or another exotic country lasts only a few days.

Frequency of earthquakes of different magnitudes in the world per year

• 1 earthquake with a magnitude of 8.0 or higher
• 10 – with a magnitude of 7.0 – 7.9 points
• 100 – with a magnitude of 6.0 – 6.9 points
• 1000 - with a magnitude of 5.0 - 5.9 points

Earthquake intensity scale

Mexico City, Mexico

One of the most densely populated cities in the world is known for its insecurity. In the 20th century, this part of Mexico felt the force of more than forty earthquakes, the magnitude of which exceeded 7 points on the Richter scale. In addition, the soil under the city is saturated with water, which makes high-rise buildings vulnerable in the event of natural disasters.

The most destructive earthquakes occurred in 1985, when about 10,000 people died. In 2012, the epicenter of the earthquake was in the southeastern part of Mexico, but vibrations were well felt in Mexico City and Guatemala, about 200 houses were destroyed.

The years 2013 and 2014 were also marked by high seismic activity in different parts of the country. Despite all this, Mexico City is still attractive to tourists due to its picturesque landscapes and numerous monuments of ancient culture.

Concepcion, Chile

Chile's second largest city, Concepción, located in the heart of the country near Santiago, regularly falls victim to tremors. In 1960, the famous Great Chilean earthquake with the highest magnitude in history, magnitude 9.5, destroyed this popular Chilean resort, as well as Valdivia, Puerto Montt, etc.

In 2010, the epicenter was again located near Concepción, about one and a half thousand houses were destroyed, and in 2013 the source sank to a depth of 10 km off the coast of central Chile (magnitude 6.6 points). However, today Concepcion does not lose popularity among both seismologists and tourists.

Interestingly, the elements have haunted Concepcion for a long time. At the beginning of its history, it was located in Penko, but due to a series of destructive tsunamis in 1570, 1657, 1687, 1730, the city was moved just south of its previous location.

Ambato, Ecuador

Today, Ambato attracts travelers with its mild climate, beautiful landscapes, parks and gardens, and massive fruit and vegetable fairs. Ancient buildings from the colonial era are intricately combined here with new buildings.

Several times this young city, located in central Ecuador, two and a half hours from the capital Quito, was destroyed by earthquakes. The most powerful tremors were in 1949, which leveled many buildings and claimed more than 5,000 lives.

Recently, seismic activity in Ecuador has continued: in 2010, an earthquake with a magnitude of 7.2 occurred southeast of the capital and was felt throughout the country; in 2014, the epicenter moved to the Pacific coast of Colombia and Ecuador, however, in these two cases there were no casualties .

Los Angeles, USA

Predicting destructive earthquakes in Southern California is a favorite pastime of geological survey specialists. The fears are fair: the seismic activity in this area is associated with the San Andreas Fault, which runs along the Pacific coast across the state.

History remembers the powerful earthquake of 1906, which claimed 1,500 lives. In 2014, the sun twice survived tremors (magnitude 6.9 and 5.1), which affected the city with minor destruction of houses and severe headaches for residents.

True, no matter how much seismologists frighten with their warnings, the “city of angels” Los Angeles is always full of visitors, and the tourist infrastructure here is incredibly developed.

Tokyo, Japan

It is no coincidence that a Japanese proverb says: “Earthquakes, fires and father are the most terrible punishments.” As you know, Japan is located at the junction of two tectonic layers, the friction of which often causes both small and extremely destructive tremors.

For example, in 2011, the Sendai earthquake and tsunami near the island of Honshu (magnitude 9) led to the death of more than 15,000 Japanese. At the same time, Tokyo residents have already become accustomed to the fact that several minor earthquakes occur every year. Regular fluctuations only impress visitors.

Despite the fact that most buildings in the capital were built taking into account possible shocks, residents are defenseless in the face of powerful disasters.

Repeatedly throughout its history, Tokyo disappeared from the face of the earth and was rebuilt again. The Great Kanto Earthquake of 1923 turned the city into ruins, and 20 years later, rebuilt, it was destroyed by large-scale bombing by American air forces.

Wellington, New Zealand

The capital of New Zealand, Wellington, seems to be created for tourists: it has many cozy parks and squares, miniature bridges and tunnels, architectural monuments and unusual museums. People come here to take part in the grandiose Summer City Program festivals and admire the panoramas that became the film set for the Hollywood trilogy The Lord of the Rings.

Meanwhile, the city was and remains a seismically active zone, experiencing tremors of varying strength from year to year. In 2013, just 60 kilometers away, a magnitude 6.5 earthquake struck, causing power outages in many parts of the country.

In 2014, Wellington residents felt tremors in the northern part of the country (magnitude 6.3).

Cebu, Philippines

Earthquakes in the Philippines are a fairly common occurrence, which, of course, does not frighten those who like to lie on the white sand or snorkel in clear sea water. On average, more than 35 earthquakes with a magnitude of 5.0-5.9 points and one with a magnitude of 6.0-7.9 occur here per year.

Most of them are echoes of vibrations, the epicenters of which are located deep under water, which creates the danger of a tsunami. The 2013 earthquakes claimed more than 200 lives and caused serious damage in one of the most popular resorts in Cebu and other cities (magnitude 7.2).

Employees of the Philippine Institute of Volcanology and Seismology are constantly monitoring this seismic zone, trying to predict future disasters.

Sumatra Island, Indonesia

Indonesia is rightfully considered the most seismically active region in the world. The westernmost one in the archipelago has become especially dangerous in recent years. It is located at the site of a powerful tectonic fault, the so-called “Pacific Ring of Fire.”

The plate that forms the floor of the Indian Ocean is being squeezed under the Asian plate here as quickly as a human fingernail grows. The accumulated tension is released from time to time in the form of tremors.

Medan is the largest city on the island and the third most populous in the country. Two major earthquakes in 2013 seriously injured more than 300 local residents and damaged nearly 4,000 homes.

Tehran, Iran

Scientists have been predicting a catastrophic earthquake in Iran for a long time - the entire country is located in one of the most seismically active zones in the world. For this reason, the capital Tehran, home to more than 8 million people, was repeatedly planned to be moved.

The city is located on the territory of several seismic faults. An earthquake of magnitude 7 would destroy 90% of Tehran, whose buildings are not designed for such violent elements. In 2003, another Iranian city, Bam, was reduced to ruins by a 6.8 magnitude earthquake.

Today Tehran is familiar to tourists as the largest Asian metropolis with many rich museums and majestic palaces. The climate allows you to visit it at any time of the year, which is not typical for all Iranian cities.

Chengdu, China

Chengdu is an ancient city, the center of the southwestern Chinese province of Sichuan. Here they enjoy a comfortable climate, see numerous sights, and become immersed in the unique culture of China. From here they travel along tourist routes to the gorges of the Yangtze River, as well as to Jiuzhaigou, Huanglong and.

Recent events have reduced the number of visitors to the area. In 2013, the province experienced a powerful earthquake with a magnitude of 7.0, when more than 2 million people were affected and about 186 thousand houses were damaged.

Residents of Chengdu annually feel the effects of thousands of tremors of varying strength. In recent years, the western part of China has become especially dangerous in terms of seismic activity of the earth.

What to do in case of an earthquake

• If an earthquake catches you on the street, do not go near the eaves and walls of buildings that may fall. Stay away from dams, river valleys and beaches.
• If an earthquake strikes you in a hotel, open the doors to freely leave the building after the first series of tremors.
• During an earthquake, you should not run outside. Many deaths are caused by falling building debris.
• In case of a possible earthquake, it is worth preparing a backpack with everything you need for several days in advance. A first aid kit, drinking water, canned food, crackers, warm clothes, and washing supplies should be at hand.
• As a rule, in countries where earthquakes are a common occurrence, all local cellular operators have a system for alerting customers about an approaching disaster. While on vacation, be careful and observe the reaction of the local population.
• After the first shock there may be a lull. Therefore, all actions after it must be thoughtful and careful.

WITH most famous strong earthquake in the history of mankind, which claimed the greatest number of lives occurred in Shaanxi and Henan in China. Estimated to have died on 2 February 1556 830 thousand people. In history 20th and 21st centuries A colossal number of vibrations of the earth's crust of enormous force were recorded, resulting in numerous human casualties. According to experts, the number major earthquakes is growing every year. Also, almost 150 are recorded annually earthquakes small magnitude. Observers attribute this to the approach of the mysterious planet Nibiru.

We bring to your attention the most strong and large earthquakes that happened on our planet in the 20th and 21st centuries, each of which resulted in a huge number of deaths, piles of destroyed buildings and homes, and a record number of people left homeless. Position in the ranking of described earthquakes very conditional.

† In terms of the number of victims, it is considered one of the most large 20th and 21st centuries Tien Shan earthquake July 28, 1976 with magnitude 7.9. Death toll reaches 750,000.

† In 1950, in the state of Assam (India), so much happened strong earthquake that all the seismographs went off scale. Its magnitude was 9 on the Richter scale.

† February 4, 1976 due to the appearance of a crack in the Motagua fault in Guatemala over 1 million inhabitants left homeless in an instant.

† Most major earthquake in the 20th century according to the scale of the Japanese seismologist Kanamori, it was observed on May 22, 1960 in Chile. Then at least 10 thousand people. Large cities were destroyed - Concepcion, which existed for more than 400 years, Valdivia, Puerto Montt, Osorno and others. The Pacific coast for more than 1000 km suffered from the rampant disaster. Coastal strip with an area of ​​10 thousand square meters. km sank below ocean level and was covered by a two-meter layer of water. 14 volcanoes have awakened. A series of subsequent aftershocks killed 5,700 people and left another 100,000 homeless. The damage caused was estimated at $400 million, and 20% of the country's industrial complex was destroyed. In 7 days (May 21-30), almost the entire Chilean countryside was reduced to ruins. The monstrous destruction on the coast was complemented by a gigantic tsunami. In particular, the port of Ankund, the capital of the island of Chiloe, was washed away. And on Easter Island, a 10-meter wave scattered, like grains of sand, multi-ton (up to 80 tons) stones of an ancient ritual structure - ahu Tongariki.

† Trouble came to the city of Verny (today Alma-Ata) on the eve of the New Year 1911. The area of ​​complete destruction (9-11 points) covered the territory with an area of ​​15 thousand square meters. km. Mountain ranges and valleys were cut by faults up to 200 km long. The strip of the greatest disturbances of the earth's surface (500 m wide and 100 km long) was recorded on the southern coast of Issyk-Kul. Millions of tons of soil have shifted.

†Greatest seismic disaster 20th century occurred on August 15, 1950 in the highlands of Tibet. The energy was approximately equal to the force of the explosion 100 thousand atomic bombs. The total weight of the displaced rocks was about 2 billion tons. Eyewitness accounts were terrifying. A deafening roar erupted from the bowels of the earth. In Calcutta, more than 1,000 km away, underground vibrations caused bouts of seasickness among residents. Cars were thrown back 800 m, a section of the railway track 300 m long was lowered by almost 5 m, and the road was completely destroyed.

† Strong 11-12 points earthquake erupted on December 4, 1957 in southern Mongolia. It started around noon with a strong jolt. Residents managed to run out of the premises, and when the subsequent main blow wiped out the buildings, almost no one was left in them. Huge dark clouds of dust rose above the mountains, initially hiding the peaks. The dust spread quickly, covering the entire 230 km long mountain range. Visibility did not exceed 100 m. The air cleared only after two days. Soil vibrations were observed over an area of ​​5 million square meters. km.

† On August 31, 2012, an explosion occurred in the central part of the Philippine archipelago. major earthquake magnitude 7.6, which led to significant destruction of roads and bridges. Residents of the island of Samar hastened to take refuge on high ground, fearing a possible tsunami. The epicenter of the earthquake was 146 km from the island. The source of the tremors lay at a depth of 32 km. Fortunately, strong earthquake did not trigger a tsunami.

† On March 11, 2011, more than 20 major earthquakes of the 21st century, the strongest with a magnitude of up to 8.9 on the Richter scale. In Tokyo, buildings swayed and a major highway collapsed. A 10 m high tsunami reached the island of Honshu, and a six meter high tsunami hit the island of Hokkaido. In Miyagi Prefecture, water washed away not only boats, houses and cars, but also tanks from a military factory. The nuclear power plant stopped operating. Authorities have decided to close Narita International Airport in Tokyo. The cataclysm led to a displacement of the Earth's rotation axis by almost ten centimeters... The official death toll in 12 prefectures of Japan is 15,870 people, 2846 people are missing in 6 prefectures, 6110 injured in 20 prefectures. 3,400 houses were completely or partially destroyed. The city of Rikuzentakata, located in the northeastern Iwate Prefecture, was almost completely submerged under water. Strong explosion occurred at the oil storage facility of the oil company Cosmo Oil in the city of Likihara, in the suburbs of Tokyo. Explosions at the Fukushima nuclear power plant led to a radiation leak... A ghost loomed over the world again nuclear death, and the suburbs of Tokyo could well become one of.

† Late August 2012 episode earthquakes deprived the residents of the small town of Brawley in California. Here 400 happened in 4 days weak and moderate tremors. Nature reminded us that we need to be prepared for anything, because this is an earthquake-prone area.

We talked about the most dangerous natural disasters 20th and 21st centuries - earthquakes, the force and consequences of which could well lead to an unprecedented global catastrophe on Earth. The threat of global disaster is real. The same elements that created our fragile planet can destroy it. The earth is not ready for strong, large earthquakes magnitude 10 or more.

Every year our planet is subjected to various disasters that destroy entire cities and lead to the death of many people. One of these includes earthquakes, which are called “earth tremors” and are associated with displacement of the earth’s crust. Today we can name the most powerful earthquakes in the world, which simply amazed us with their destructive power and number of victims.

China: great earthquake (1556)

Asian countries are often hit by severe natural disasters. This natural disaster of the mid-16th century, which occurred in the provinces of Shaanxi and Henan, was of such enormous proportions that had not previously been known. This magnitude 9 earthquake, accompanied by the formation of 20-meter cracks, claimed the lives of 830,000 people. The settlements that were located in the disaster zone were completely destroyed.

Earthquake in Kanto (Japan, 1923)

The full power of the 12-magnitude tremors was felt by the Japanese Southern Konto (Tokyo and Yokohama are located here) in 1923. The destructive forces of nature were joined by fires, which greatly aggravated the situation. The flames rose up almost 60 meters - this is how the spilled gasoline burned. As a result of this and because of the destroyed infrastructure, rescuers were unable to organize their work effectively. This disaster killed approximately 170,000 people.

Assam earthquake (India, 1950)

This earthquake, which occurred in Indian Assami, was the most powerful. The element was assigned a magnitude of 9, but eyewitnesses claim that the tremors were much more powerful. This earthquake caused the death of 1,000 people and great destruction. A few years earlier, there was also an earthquake here, which was striking in its scale - an area of ​​390,000 km2 was turned into ruins, and the death toll was 1,500 people.

Earthquake in Chile (1960)

Chilean Valdivia was virtually destroyed by this earthquake, which caused the death of 6,000 people and the loss of shelter over the heads of approximately 2,000,000 people. Most of the population living here suffered from a tsunami caused by tremors, the height of which was at least 10 meters. According to various sources, the strength of the earthquake was 9.3-9.5.

Alaska earthquake (1964)

This earthquake was very destructive in its strength. It was rated 9.2 points. The earthquake itself killed 9 people, but the tsunami it caused led to the death of another 190 people. The tsunami was quite destructive, causing serious destruction in many communities from Canada to Japan.

Earthquake in Tangshan (China, 1976)

This is the second natural disaster in China, which is characterized by a terrifying number of victims and great power of destruction. The very center of the earthquake was in Tangshan (the city has a population of millions). The tremors were 7.9-8.2 points. The disaster led to colossal destruction, the number of victims was 650,000 people. Another 780,000 were wounded.

Armenian earthquake (1988)

The power of this earthquake, which completely turned the city of Spitak, located at the epicenter of the cataclysm, into ruins, was 10 points. There was a lot of destruction in nearby settlements. The number of victims was approximately 45,000 people.

Underwater tremors in the Indian Ocean (2004)

This underwater earthquake was the third most powerful in the entire history of observing such cataclysms. The underwater tremors that occurred in the Indian Ocean had a force of 9.1-9.3 points. The epicenter was located near the island of Sumatra. This earthquake caused a huge tsunami. The total number of victims of the disaster was about 300,000 people.

Earthquake in China (2008)

And again the territory of China was subjected to a formidable disaster - this time an earthquake of 7.9 points occurred in Sichuan. Tremors were even felt in Shanghai and Beijing. 70,000 people died as a result of this natural disaster.

Earthquake in Japan (2011)

This 9.0-magnitude earthquake became another natural disaster in Japan with enormous destructive scale. The consequence of the tremors was a tsunami, which damaged a nuclear power plant, and this became a threat of radioactive contamination of the environment.

The power of tremors is estimated by the amplitude of oscillations of the earth's crust from 1 to 10 points. Areas in mountainous areas are considered the most earthquake-prone. We present to you the most powerful earthquakes in history.

The worst earthquakes in history

The large number of victims is associated not so much with the strength of the tremors, but with their duration. Modern researchers can judge the consequences of the destruction of the earthquake in the 2nd century only from the surviving chronicles, according to which the cities of Catania, Messina and Ragusa in Sicily were practically destroyed, and the coastal cities of Akratiri and Paralimni in Cyprus were also covered by a strong wave.

Earthquake on the island of Haiti

Despite the fact that the earthquake occurred in 2010, Haitians still need humanitarian assistance and are also rebuilding settlements on their own. This is the second most powerful earthquake in Haiti, the first occurred in 1751 - then the cities had to be rebuilt over the next 15 years.

Earthquake in China

Within 6 months after the main earthquake, so-called aftershocks were repeatedly felt - repeated seismic tremors with a power of 1-2 points. This disaster occurred during the reign of Emperor Jiajing, so it is called the Great Jiajing Earthquake in Chinese history.

The most powerful earthquakes in Russia

Earthquake on Sakhalin

The most significant consequences were felt in Neftegorsk, which was 30 kilometers from the epicenter of the earthquake. Within 17 seconds, almost all houses were destroyed. The damage caused amounted to 2 trillion rubles, and the authorities decided not to restore the settlements, so this city is no longer indicated on the map of Russia.

More than 1,500 rescuers were involved in eliminating the consequences. 2,040 people died under the rubble. A chapel was built and a memorial was erected on the site of Neftegorsk.

Earthquake in Japan

Tremors in the Pacific Ocean caused a powerful tsunami, the height of the waves was 10 meters. As a result of the collapse of a large flow of water on the coast of Japan, a radiation accident occurred at the Fukushima-1 nuclear power plant. Subsequently, for several months, residents of nearby areas were prohibited from drinking tap water due to its high cesium content.

In addition, the Japanese government ordered TEPCO, which owns the nuclear power plant, to compensate moral damages to 80 thousand residents forced to leave the contaminated areas.

The most powerful earthquake in the world

The strongest tremors were felt in the state of Assam, which was reduced to ruins as a result of the earthquake - more than two thousand houses were destroyed and more than six thousand people were killed. The total area of ​​the territories caught in the destruction zone was 390 thousand square kilometers.

According to the site, earthquakes also often occur in volcanically active areas. We present to you an article about the highest volcanoes in the world.
