Every day various areas of our planet are shaken by tremors. An earthquake is one of the natural disasters that cannot be prevented by man.

The only thing he can oppose to the indomitable forces of nature is the achievements of science in the field of forecasting. Systematization and monitoring of seismic activity makes it possible to avoid human casualties and destruction in time, as well as to identify areas of the greatest seismic activity.

Accounting for earthquake sources

The Earth seismic activity map is a physical map of the planet, which displays areas where earthquakes with a power of more than 4 on the Richter scale occurred over a certain period of time. The following conventions are used on the map: the diameter of the area is proportional to the power of the tremors, and the color of the circle indicates the time interval. For example, red areas correspond to earthquakes occurring on the current date or in real time.

Today it is no secret to anyone that on all continents of our planet there is a significant increase in cataclysms and natural disasters, which are associated with cosmic cyclic processes and, as a result, global climate change. The increase in activity and frequency of natural disasters on a planetary scale falls on seismic activity. Scientists around the world are concerned about the constantly changing data on the increase in the number of earthquakes. Not only their number is growing, but also the intensity, location, nature of destructive actions.

So, the area of ​​special attention for the scientific direction of climate geoengineering and the entire world community today are two points on different hemispheres of the globe - the Yellowstone caldera in the USA and the Aira caldera in Japan. These are two huge underground volcanoes, standing at the junction of lithospheric plates. According to scientists, the activation of one of them can lead to the subsequent activation of the other, and this is not only a large-scale eruption, but also earthquakes, tsunamis and other consequences. The scale of such a global catastrophe is difficult to assess.

This and other important issues of early warning of people about impending cataclysms were openly stated in 2014 by the world community of ALLATRA SCIENCE scientists in the report “On the Problems and Consequences of Global Climate Change on Earth. Effective ways to solve these problems.

Earthquake.

According to the official terminology, an earthquake is a shaking of the earth's surface or underground points, which are a reflection of the internal geological changes of the planet. This effect is based on the displacement of tectonic plates, which lead to ruptures of the earth's crust and mantle. As a result, oscillatory movements, depending on the intensity of the process, can spread over long distances, bringing with them not only a destructive effect on social infrastructure, but also a threat to people's lives.

This issue deals with a special science - seismology. Several areas are being actively studied, including: deepening in knowledge of what seismic activity is in its essence and what it is connected with, possible forecasting of these natural disasters, for timely warning and evacuation of people. Like any other science, seismology can actively develop only in mutually beneficial symbiosis with other sciences (physics, history, biology, geophysics, etc.), since the fundamental basis for all knowledge on our planet is, of course, common.

Seismic activity online and in the world.

Seismic monitoring is developing in most countries, regardless of the territory, frequency and threat of earthquake development. In addition, a seismic monitor is one of the fundamental factors in the development and preservation of the integrity of energy industry facilities. Almost every person on the planet today is an active consumer of electricity. Therefore, power plants are located in all countries and on all continents, including the zone of increased seismic hazard. The action of such a destructive force of nature is fraught not only with an energy catastrophe, but also with global environmental problems.

In order to control seismic processes (earthquakes), study them and warn the public in advance about their occurrence, seismic stations are built in designated areas. All the necessary characteristics of tremors are studied - the magnitude, location and depth of the source.

Earthquakes online.

For all people, thanks to Internet technologies, data is also available today: “earthquakes online”. This is the so-called earthquake map, which provide information about tremors around the world around the clock.

Active participants of ALLATRA International Public Movement have developed the most complete map of seismic activity, which displays objective data from world information portals and seismic monitoring stations. Informing the public and awareness of the processes taking place on the planet, their causes and consequences is the main task of this project.

Today, each person can observe a significant increase in abnormal weather changes, natural disasters, and cataclysms. The active participation of all people, unity, mutual assistance and friendship, the prevalence of true moral and spiritual values ​​in society is the key to the survival of civilization in the future.

An earthquake is a violent shaking of the Earth's surface resulting from a sudden release of energy in the earth's crust, which creates seismic waves. It is one of the deadliest natural disasters and often results in ground breaking, earth trembling and liquefaction, landslides, tremors or tsunamis.

If we look at the structure of the earthquakes that occur around the world, it becomes clear that most of the seismic activity is concentrated in a number of different earthquake belts. Earthquakes are unpredictable in terms of when they strike, but certain areas are the most likely to hit.

The world map of earthquakes shows that most of them lie in precise zones, often along the edges of the continents or in the middle of the ocean. The world is divided into seismic zones based on tectonic plates and earthquake magnitude. Here list of the most earthquake-prone countries in the world:


Several cities are also vulnerable to earthquake damage in Indonesia. Indonesia's capital, Jakarta, is in a difficult position. Not only is it located atop the Pacific Ring of Fire, but, just under half the city is below sea level, it sits on soft ground that has the potential to liquefy if struck by an earthquake of sufficient magnitude.

But the complications don't end there. The height of Jakarta also puts the city at risk of flooding. On December 26, 2004, an earthquake occurred in the Indian Ocean with its epicenter on the west coast of the island of Sumatra, Indonesia.

A mega-strength underwater earthquake occurred when the Indian Plate subducted under the Burma Plate and triggered a series of devastating tsunamis along the coast of much of the Indian Ocean coastline, killing 230,000 people in 14 countries, and flooding coastal areas with waves up to 30 meters high.

Indonesia was the most affected area, with the most deaths estimated at around 170,000. This is the third largest earthquake ever recorded on seismographs.


Turkey is located in the seismic zone between the Arabian, Eurasian and African plates. This geographic location suggests that an earthquake can occur in the country at any given time. Turkey has a long history of large earthquakes, which often occur in progressive contiguous earthquakes.

The magnitude 7.6 earthquake that hit western Turkey on August 17, 1999 is one of the world's longest and most well-studied strike-slip (horizontal) faults: the East-West strike of the North Anatolian Fault.

The incident lasted only 37 seconds, killing about 17,000 people. Over 50,000 people were injured and over 5,000,000 people were left homeless, making it one of the most devastating earthquakes of the 20th century.


Mexico is another earthquake prone country and has experienced several high magnitude earthquakes in the past. Located on three large tectonic plates, namely the Cocos Plate, the Pacific Plate and the North American Plate, which make up the earth's surface, Mexico is one of the most seismically active areas on earth.

The movement of these plates causes earthquakes and volcanic activity. Mexico has an extensive history of devastating earthquakes and volcanic eruptions. In September 1985, an earthquake measuring 8.1 on the Richter scale was concentrated in the 300-kilometer subduction zone off Acapulco, killing 4,000 people in Mexico City.

One of the recent earthquakes occurred in 2014 in the state of Guerrero with a magnitude of 7.2, the impact caused numerous casualties in the region.


El Salvador is another dangerous seismically active country where massive damage was done due to the earthquake. The small Central American Republic of El Salvador has experienced, on average, one devastating earthquake per decade over the past hundred years. There were two large earthquakes on January 13 and February 13, 2001, with magnitudes of 7.7 and 6.6, respectively.

These two events, which have different tectonic origins, show patterns in the region's seismicity, although neither of these events had known precedents in the earthquake catalog in terms of size and location. Earthquakes damaged thousands of traditionally built houses and caused hundreds of landslides, which are the main causes of deaths.

Earthquakes have clearly demonstrated the trend towards increasing seismic risk in El Salvador due to rapid population growth in areas of high quake and landslide risk, the situation is exacerbated by deforestation and uncontrolled urbanization. The institutional arrangements needed to control land use and building practices are very weak and represent a major barrier to risk reduction.


Another earthquake-prone country is Pakistan, which is geologically and chemically located in the Indus-Tsangpo suture zone, which is about 200 km north of the front Himalayas and is defined by an ophiolite chain along the southern margin. This region has the highest rates of seismic activity and the largest earthquakes in the Himalaya region, caused mainly by fault movement.

A 7.6 magnitude earthquake hit Pakistan's Kashmir in October 2005, killing more than 73,000 people, many in remote parts of the country, in sparsely populated urban centers such as Islamabad. More recently, in September 2013, a powerful earthquake measuring 7.7 on the Richter scale occurred, causing massive damage to people's lives and property, killing at least 825 people and injuring hundreds of people.


The Philippines lies on the edge of the Pacific Plate, which has traditionally been considered a seismically hot zone that surrounds the state. The danger of earthquakes in Manila is created three times more often. The city comfortably adjoins the Pacific Ring of Fire, which, of course, makes it especially sensitive not only to earthquakes, but also to volcanic eruptions.

The threat to Manila is aggravated by soft soil, which poses a risk of soil liquefaction. On October 15, 2013, an earthquake measuring 7.1 on the Richter scale hit the central Philippines. According to official statistics from the National Disaster Reduction and Management Council (NDRRMC), 222 people died, 8 were missing, and 976 people were injured.

Overall, more than 73,000 buildings and structures were damaged, of which more than 14,500 were completely destroyed. It was the deadliest earthquake in the Philippines in 23 years. The power released by the earthquake was equivalent to 32 Hiroshima bombs.


Ecuador has several active volcanoes, making the country extremely prone to high magnitude earthquakes and tremors. The country is located in a seismic zone between the South American Plate and the Nazca Plate. Earthquakes that affect Ecuador can be divided into those that are the result of movement along the subduction junction along the plate boundary, those that are the result of deformation within the S American and Nazca Plates, and those associated with active volcanoes.

On August 12, 2014, an earthquake of magnitude 5.1 on the Richter scale struck Quito, followed by an aftershock of magnitude 4.3. 2 people died and 8 were injured.


India has also experienced a series of several deadly earthquakes due to the movement of the Indian tectonic plate at a rate of 47mm every year. Due to the movement of tectonic plates, India is prone to earthquakes. India has been divided into five zones based on peak ground acceleration.

On December 26, 2004, an earthquake generated the third deadliest tsunami in the history of the world, killing 15,000 people in India. The earthquake in the state of Gujarat occurred on January 26, 2001, on the celebration of the 52nd day of the Republic of India.

It lasted more than 2 minutes and amounted to 7.7 points on the kanamori scale, according to statistics, from 13,805 to 20,023 people died, another 167,000 people were injured and about 400,000 houses were destroyed.


If the calculations are correct, then a citizen in Nepal is more likely to die in an earthquake than any citizen in the world. Nepal is a country prone to natural disasters. Floods, landslides, epidemics and fires cause significant property damage in Nepal every year. It is one of the most seismically active regions in the world.

Mountains are built as a result of the movement of Indian tectonic plates under Central Asia. These two large plates of the earth's crust are approaching at a relative rate of 4-5 cm per year. The peaks on Everest and its sister mountains are subject to numerous aftershocks. In addition, the remains of a prehistoric lake, in a 300-meter deep layer of black clay, lie in the lowlands of the Kathmandu valley. This increases the damage from strong earthquakes.

Thus, the region becomes susceptible to soil liquefaction. During strong earthquakes, solid ground turns into something like quicksand, swallowing everything above the ground. In April 2015, an earthquake in Nepal killed over 8,000 people and injured more than 21,000. The earthquake triggered an avalanche on Everest where 21 people died, making 25 April 2015 the deadliest day on the mountain in history.


Japan tops the list of earthquake-prone areas. Japan's physical geographic location along the Pacific Ring of Fire makes the country very sensitive to earthquakes and tsunamis. Ring of Fire - The tectonic plates in the Pacific Basin are responsible for 90% of the world's earthquakes and 81% of the world's strongest earthquakes.

At the pinnacle of its prolific tectonic activity, Japan is also home to 452 volcanoes, making it the most destructive geographic location in terms of natural disasters. The powerful earthquake that hit Japan on March 11, 2011 struck hard and became one of the five largest earthquakes in the world since the beginning of seismological records.

It was followed by a tsunami with waves up to 10 m high. The disaster killed thousands of people and caused extensive damage to buildings and infrastructure, which led to significant accidents at four large nuclear power plants.

You will see the effects of the most powerful earthquakes in the world and understand why this phenomenon is considered so dangerous.

The strongest earthquakes throughout the history of mankind caused enormous material damage and caused a huge number of casualties among the population. The first mention of tremors date back to 2000 BC.
And despite the achievements of modern science and the development of technology, no one still can predict the exact time when the elements will strike, so it often becomes impossible to quickly and timely evacuate people.

Earthquakes are natural disasters that kill the most people, much more than, for example, hurricanes or typhoons.
In this rating, we will talk about the 12 most powerful and destructive earthquakes in the history of mankind.

12. Lisbon

November 1, 1755, in the capital of Portugal, the city of Lisbon, there was a strong earthquake, later called the Great Lisbon Earthquake. It was a terrible coincidence that on November 1, All Saints Day, thousands of residents gathered for mass in the churches of Lisbon. These churches, like other buildings throughout the city, could not withstand the powerful shocks and collapsed, burying thousands of unfortunate people under their rubble.

Then a 6-meter tsunami wave poured into the city, covering the survivors, rushing in panic along the streets of the destroyed Lisbon. The destruction and loss of life was enormous! As a result of the earthquake, which lasted no more than 6 minutes, caused by a tsunami and numerous fires that engulfed the city, at least 80,000 residents of the capital of Portugal died.

Many famous figures and philosophers dealt with this deadly earthquake in their works, for example, Immanuel Kant, who tried to find a scientific explanation for such a large-scale tragedy.

11. San Francisco

On April 18, 1906, at 5:12 am, powerful tremors shook the sleeping San Francisco. The force of the shocks was 7.9 points and as a result of a strong earthquake in the city, 80% of the buildings were destroyed.

After the first count of the dead, the authorities reported 400 victims, but later their number increased to 3,000 people. However, the main damage to the city was caused not by the earthquake itself, but by the monstrous fire caused by it. As a result, more than 28,000 buildings were destroyed throughout San Francisco, and property damage amounted to more than $ 400 million at the rate of that time.
Many residents themselves set fire to their dilapidated houses, which were insured against fire, but not against earthquakes.

10. Messina

The largest earthquake in Europe was the earthquake in Sicily and Southern Italy, when on December 28, 1908, as a result of the most powerful tremors with a force of 7.5 on the Richter scale, according to various experts, from 120 to 200,000 people died.
The epicenter of the disaster was the Strait of Messina, located between the Apennine Peninsula and Sicily, the city of Messina suffered the most, where there was practically not a single surviving building left. A huge tsunami wave, caused by tremors and reinforced by an underwater landslide, also brought a lot of destruction.

Documented fact: rescuers were able to pull two malnourished, dehydrated, but alive children from the rubble, 18 days after the disaster! Numerous and extensive destruction was caused primarily by the poor quality of buildings in Messina and other parts of Sicily.

Russian sailors of the imperial fleet provided invaluable assistance to the inhabitants of Messina. The ships as part of the training group sailed the Mediterranean and on the day of the tragedy ended up in the port of Augusta in Sicily. Immediately after the tremors, the sailors organized a rescue operation and thanks to their courageous actions, thousands of residents were saved.

9. Haiyuan

One of the deadliest earthquakes in human history was the devastating earthquake that hit Haiyuan County in Gansu Province on December 16, 1920.
Historians estimate that at least 230,000 people died that day. The strength of the tremors was such that entire villages disappeared in the faults of the earth's crust, such large cities as Xi'an, Taiyuan and Lanzhou were very badly damaged. Incredibly, but strong waves formed after the impact of the elements were recorded even in Norway.

Modern researchers believe that the death toll was much higher and totals at least 270,000 people. At that time, it was 59% of the population of Haiyuan County. Several tens of thousands of people died from the cold after their homes were destroyed by the elements.

8. Chile

The earthquake in Chile on May 22, 1960, is considered the strongest earthquake in the history of seismology, the magnitude of the tremors was 9.5 on the Richter scale. The earthquake was so powerful that it caused tsunami waves over 10 meters high, covering not only the coast of Chile, but also causing great damage to the city of Hilo in Hawaii, and some of the waves reached the coast of Japan and the Philippines.

More than 6,000 people died, most of them hit by the tsunami, the destruction was unimaginable. 2 million people were left without housing and shelter, and the amount of damage amounted to more than 500 million dollars. In some areas of Chile, the impact of the tsunami wave was so strong that many houses were blown 3 km inland.

7. Alaska

On March 27, 1964, the most powerful earthquake in American history hit Alaska. The force of the rumors was 9.2 on the Richter scale and this earthquake became the strongest since the elements struck in Chile in 1960.
129 people died, of which 6 were unfortunate victims of the tremors, the rest were washed away by a huge tsunami wave. The elements caused the greatest destruction in Anchorage, and tremors were registered in 47 US states.

6. Kobe

The earthquake in Kobe, Japan on January 16, 1995 was one of the most devastating in history. Tremors with a force of 7.3 points began at 05:46 am local time and lasted for several days. As a result, more than 6,000 people died, 26,000 were injured.

The damage done to the infrastructure of the city was simply enormous. More than 200,000 buildings were destroyed, 120 out of 150 berths were destroyed in the port of Kobe, and there was no power supply for several days. The total damage from the impact of the elements amounted to about 200 billion dollars, which at that time was 2.5% of Japan's total GDP.

Not only government services rushed to help the affected residents, but also the Japanese mafia - the yakuza, whose members delivered water and food to the victims of the disaster.

5. Sumatra

On December 26, 2004, the strongest tsunami that hit the coasts of Thailand, Indonesia, Sri Lanka and other countries was caused by a devastating earthquake measuring 9.1 on the Richter scale. The epicenter of the tremors was in the Indian Ocean, near the island of Simeulue, off the northwestern coast of Sumatra. The earthquake was unusually large, there was a shift of the earth's crust at a distance of 1200 km.

The height of the tsunami waves reached 15-30 meters and according to various estimates, from 230 to 300,000 people became victims of the disaster, although it is impossible to calculate the exact number of deaths. Many people were simply washed away into the ocean.
One of the reasons for this number of victims was the lack of an early warning system in the Indian Ocean, with which it was possible to inform the local population about the approaching tsunami.

4. Kashmir

On October 8, 2005, in the Kashmir region, which is under the control of Pakistan, there was the strongest earthquake in South Asia in the last hundred years. The force of the tremors was 7.6 on the Richter scale, which is comparable to the San Francisco earthquake in 1906.
According to official data, 84,000 people died as a result of the disaster, and more than 200,000 according to unofficial data. Rescue work was hampered by the military conflict between Pakistan and India in the region. Many villages and villages were completely wiped off the face of the earth, and the city of Balakot in Pakistan was also completely destroyed. In India, 1300 people became victims of the earthquake.

3. Haiti

On January 12, 2010, Haiti was hit by an earthquake measuring 7 on the Richter scale. The main blow fell on the capital of the state - the city of Port-au-Prince. The consequences were terrible: almost 3 million people were left homeless, all hospitals and thousands of residential buildings were destroyed. The number of victims was simply enormous, according to various estimates from 160 to 230,000 people.

Criminals who escaped from the prison destroyed by the elements poured into the city, cases of looting, robberies and robberies became frequent on the streets. The material damage from the earthquake is estimated at 5.6 billion dollars.

Despite the fact that many states - Russia, France, Spain, Ukraine, the USA, Canada and dozens of others - provided all possible assistance in eliminating the consequences of the Haiti disaster, more than five years after the earthquake, more than 80,000 people still live in impromptu camps for refugees.
Haiti is the poorest country in the western hemisphere and this natural disaster dealt an irreparable blow to the economy and the standard of living of citizens.

2. Earthquake in Japan

On March 11, 2011, the strongest earthquake in Japanese history struck the Tohoku region. The epicenter was located east of the island of Honshu and the strength of the tremors was 9.1 on the Richter scale.
As a result of the disaster, the nuclear power plant in the city of Fukushima was badly damaged and power units at reactors 1, 2, and 3 were destroyed. Many areas became uninhabitable as a result of radioactive radiation.

After underwater tremors, a huge tsunami wave covered the coast and destroyed thousands of administrative and residential buildings. More than 16,000 people died, 2,500 are still considered missing.

The material damage also turned out to be colossal - more than 100 billion dollars. And given that it may take years to completely restore the destroyed infrastructure, the amount of damage can increase several times.

1. Spitak and Leninakan

There are many tragic dates in the history of the USSR, and one of the most famous is the earthquake that shook the Armenian SSR on December 7, 1988. The most powerful tremors in just half a minute almost completely destroyed the northern part of the republic, capturing the territory where more than 1 million inhabitants lived.

The consequences of the disaster were monstrous: the city of Spitak was almost completely wiped off the face of the Earth, Leninakan was badly damaged, more than 300 villages were destroyed and 40% of the industrial capacities of the republic were destroyed. More than 500 thousand Armenians were left homeless, according to various estimates, from 25,000 to 170,000 people died, 17,000 citizens were left disabled.
Assistance in the restoration of destroyed Armenia was provided by 111 states and all the republics of the USSR.
