Where does the earthquake occur map. Interactive map of volcanic activity

Every day, various areas of our planet are shaken by tremors. An earthquake is one of the natural disasters that humans cannot prevent.

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 casualties and destruction in a timely manner, as well as to identify areas of the greatest seismic activity.

Accounting for earthquake sources

The Earth's seismic activity map is physical card planet, which displays areas where earthquakes with a power of more than 4 points on the Richter scale occurred over a certain period of time. The map uses the following symbols: The diameter of the area is proportional to the strength 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.

Seismic monitor, updated every 20 minutes

red circles - earthquakes in the last 24 hours
orange circles - earthquakes in the last 1-4 days
yellow circles - earthquakes in the last 4-14 days

EMSC and Google Map data

The map of seismic activity of the world allows you to select an area by clicking the mouse button earth's surface. In this case, the selected area will be separately displayed in the window, in which the epicenters of earthquakes are indicated in detail. The online seismic monitor allows you to obtain comprehensive data when selecting any source. The table shows the coordinates of the epicenters and the power of tremors, ranging from 24 hours to 30 days. The seismic recording stations located in the selected area are also displayed on the map of the area.

Earthquakes are scary a natural phenomenon, which can bring numerous troubles. They are associated not only with destruction, which may result in human casualties. The catastrophic tsunami waves they cause can lead to even more disastrous consequences.

For which areas globe Are earthquakes the greatest danger? To answer this question, you need to look at where the active seismic areas are. These are zones earth's crust, which are more mobile than their surrounding regions. They are located at the boundaries of lithospheric plates, where collisions or separation of large blocks occur. It is the movements of thick layers rocks and cause earthquakes.

Dangerous areas of the world

There are several belts on the globe that are characterized by a high frequency of underground impacts. These are seismically dangerous areas.

The first of them is usually called the Pacific Ring, since it occupies almost the entire ocean coast. Not only earthquakes are frequent here, but also volcanic eruptions, which is why the name “volcanic” or “ring of fire” is often used. The activity of the earth's crust here is determined by modern mountain-building processes.

The second large seismic belt stretches along the high young of the Alps and other mountains Southern Europe and to the Sunda Islands through Asia Minor, the Caucasus, the mountains of Central and Central Asia and the Himalayas. The collision of lithospheric plates also occurs here, which causes frequent earthquakes.

The third belt stretches across the entire Atlantic Ocean. This is the Mid-Atlantic Ridge, which is the result of the spreading of the earth's crust. Iceland, known primarily for its volcanoes, also belongs to this belt. But earthquakes here are by no means a rare phenomenon.

Seismically active regions of Russia

Earthquakes also occur in our country. Seismically active regions of Russia are the Caucasus, Altai, the mountains of Eastern Siberia and Far East, Commander's and Kurile Islands, O. Sakhalin. Tremors of great force can occur here.

One can recall the Sakhalin earthquake of 1995, when two-thirds of the population of the village of Neftegorsk died under the rubble of destroyed buildings. After the rescue work, it was decided not to restore the village, but to relocate the residents to other settlements.

In 2012-2014, several earthquakes occurred in the North Caucasus. Fortunately, their sources were located at great depths. There were no casualties or serious damage.

Seismic map of Russia

The map shows that the most seismically dangerous areas lie in the south and east of the country. At the same time, the eastern parts are relatively sparsely populated. But in the south, earthquakes pose a much greater danger to people, since the population density here is higher.

Irkutsk, Khabarovsk and some others big cities find themselves in the danger zone. These are active seismic areas.

Anthropogenic earthquakes

Seismically active areas occupy approximately 20% of the country's territory. But this does not mean that the rest is completely insured against earthquakes. Tremors with a force of 3-4 points are observed even far from the boundaries of lithospheric plates, in the center of platform areas.

At the same time, with the development of the economy, the possibility of anthropogenic earthquakes increases. They are most often caused by the collapse of the roof of underground voids. Because of this, the earth's crust seems to shake, almost like a real earthquake. And there are more and more voids and cavities underground, because people extract oil from the depths for their needs and natural gas, pumps out water, builds mines for the extraction of solid minerals... And underground nuclear explosions generally comparable in strength to natural earthquakes.

The collapse of rock layers in itself can pose a danger to people. Indeed, in many areas, voids form directly under settlements. Recent events in Solikamsk have only confirmed this. But even a weak earthquake can lead to dire consequences, because as a result it can destroy structures that are in disrepair, dilapidated housing in which people continue to live... Also, violation of the integrity of rock layers threatens the mines themselves, where collapses can occur.

What to do?

People are not yet able to prevent such a terrible phenomenon as an earthquake. And they haven’t even learned to predict exactly when and where it will happen. This means you need to know how you can protect yourself and your loved ones during tremors.

People living in such dangerous areas should always have an earthquake plan in place. Since a disaster may find family members in different places, there should be an agreement on a meeting place after the tremors stop. The home should be as safe as possible from falling heavy objects; it is best to attach furniture to the walls and floor. All residents should know where they can urgently turn off gas, electricity, and water in order to avoid fires, explosions and electric shocks. Stairs and passages should not be cluttered with things. Documents and a certain set of products and essentials should always be at hand.

Starting from kindergartens and schools, the population needs to be taught correct behavior in case of a natural disaster, which will increase the chances of rescue.

Seismically active regions of Russia place special demands on both industrial and civil engineering. Earthquake-resistant buildings are more difficult and expensive to build, but the cost of their construction is nothing compared to the lives saved. After all, not only those who are in such a building will be safe, but also those nearby. There will be no destruction and rubble - there will be no casualties.

An earthquake is a strong shaking of the Earth's surface resulting from the sudden release of energy in the earth's crust, which creates seismic waves. It is one of the most deadly natural disasters and often leads to fractures of the earth's surface, shaking and liquefaction of the earth, landslides, tremors or tsunamis.

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

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

Several cities are also vulnerable to damage from the Indonesia earthquake. Indonesia's capital, Jakarta, is in a difficult situation. Not only does it sit atop the Pacific Ring of Fire, but with slightly less than half the city below sea level, it sits on soft soil that has the potential to liquefy if struck by an earthquake of sufficient magnitude.

But the complications don't end there. Jakarta's altitude 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 Sumatra, Indonesia.

A mega-magnitude undersea earthquake occurred when the Indian Plate subducted under the Burma Plate and generated a series of devastating tsunamis along much of the coastline washed by the waters Indian Ocean, killed 230,000 people in 14 countries, and coastal areas were inundated by waves up to 30 meters high.

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

Türkiye lies in a seismic zone between the Arabian, Eurasian and African plates. This geographical location assumes that an earthquake can occur in the country at any time. Türkiye has a long history of large earthquakes, which often occur in progressive contiguous earthquakes.

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

The incident lasted only 37 seconds and killed approximately 17,000 people. More than 50,000 people were injured and more than 5,000,000 people were left homeless, making it one of the most destructive earthquakes of the 20th century.

Mexico is another earthquake-prone country and has experienced several high magnitude earthquakes in the past. Situated 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 centered on a 300-kilometer subduction zone off Acapulco, killing 4,000 people in Mexico City.

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

El Salvador is another seismically active country that has suffered massive damage due to earthquakes. The small Central American Republic of El Salvador has experienced an average of one devastating earthquake per decade over the past hundred years. Two large earthquakes occurred on January 13 and February 13, 2001, with magnitudes of 7.7 and 6.6, respectively.

These two events, which have different tectonic origins, reveal patterns of seismicity in the region, although neither event has a known precedent in the earthquake catalog in terms of size and location. The earthquakes have damaged thousands of traditionally built houses and caused hundreds of landslides, which are the leading causes of deaths.

The earthquakes have clearly demonstrated the increasing trends in seismic risk in El Salvador due to rapid population growth in areas of increased risk of tremors and landslides, a situation aggravated by deforestation and uncontrolled urbanization. The institutional mechanisms needed to control land use and construction practices are very weak and pose a major obstacle to risk reduction.

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

A magnitude 7.6 earthquake struck 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 enormous damage to lives and property, killing at least 825 people and injuring hundreds.

The Philippines lies on the edge of the Pacific Plate, which is traditionally considered a seismically hot zone that surrounds the state. The risk of earthquakes in Manila is three times higher. The city is comfortably adjacent to 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 worsened by soft soil, which poses a risk of liquefaction. On October 15, 2013, an earthquake measuring 7.1 on the Richter scale struck the central Philippines. According to official statistics from the National Disaster Risk Reduction and Management Council (NDRRMC), 222 people were killed, 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 to hit the Philippines in 23 years. The power released by the earthquake was equivalent to 32 Hiroshima bombs.

Ecuador has several active volcanoes, which makes the country extremely dangerous for earthquakes with powerful magnitude and tremors. The country is located in the seismic zone between the South American plate and the Nazca plate. Earthquakes that affect Ecuador can be divided into those that result from movement along a subduction junction along a plate boundary, those that result from deformation within the South American and Nazca plates, and those that are associated with active volcanoes.

On August 12, 2014, an earthquake measuring 5.1 on the Richter scale rocked Quito, followed by an aftershock measuring 4.3. 2 people were killed and 8 were injured.

India has also experienced a number of several deadly earthquakes due to the movement of the Indian tectonic plate at a rate of 47 mm 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 created the third deadliest tsunami in the history of the world, killing 15,000 people in India. The earthquake in Gujarat occurred on January 26, 2001, on the occasion of the 52nd Republic Day 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 were killed, another 167,000 people were injured and about 400,000 houses were destroyed.

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

Mountains are built due to the movement of Indian tectonic plates under Central Asia. These two large crustal plates are moving closer together at a relative rate of 4-5 cm per year. The peaks on Everest and its sister mountains are subject to numerous tremors. Moreover, 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 large earthquakes.

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

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

At the height of its prolific tectonic activity, Japan is also home to 452 volcanoes, making it the most destructive geographical location from point of view natural disasters. The powerful earthquake that struck Japan on March 11, 2011 dealt a powerful blow and became one of the five largest earthquakes in the world since seismological records began.

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

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

Today it is no longer a secret to anyone that on all continents of our planet there is a significant increase in cataclysms and natural disasters that are associated with cosmic cyclical processes and, as a consequence, global climate change. The increase in activity and frequency of natural disasters on a planetary scale is due to 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 increases, but also the intensity, location, and nature of destructive actions.

Yes, the region special attention For scientific direction 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 located 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 is like this global catastrophe difficult to assess.

This and other important issues of early warning of people about impending disasters were openly stated in 2014 global community ALLATRA SCIENCE scientists in the report “On the problems and consequences global change climate on Earth. Effective ways solutions to these problems."

Earthquake.

According to official terminology, an earthquake is a vibration of the earth's surface or underground points that are a reflection of the internal geological changes of the planet. The basis for this effect is the displacement of tectonic plates, which lead to ruptures in 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 is dealt with by a special science – seismology. Several areas are being actively studied, including: deepening the knowledge of what seismic activity is in 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 a 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 earthquakes. 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 areas of high seismic hazard. The action of such a destructive force of nature is fraught not only with an energy disaster, 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 necessary characteristics of tremors are studied - magnitude, location and depth of the source.

Earthquakes online.

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

Active participants of the International social movement ALLATRA has developed the most full map seismic activity, which displays objective data from world information portals and seismic monitoring stations. Informing the public and awareness of the processes occurring on the planet, their causes and consequences is the main goal of this project.

Today, every person can observe a significant increase in abnormal weather changes, natural disasters, cataclysms. The active participation of all people, unification, 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.
