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 seismicity map is a physical map of the planet that shows areas where earthquakes greater than 4 on the Richter scale have occurred over a certain period of time. The map uses the following conventions: 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.

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 of ​​the earth's surface by clicking the mouse button. 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.

And introduce you to a couple more wonderful services.

There are many seismically active areas on planet Earth, where tremors occur with a certain frequency. Their causes are overwhelmingly natural and caused by the movements of tectonic plates. Despite actively developing research in this area and good technical equipment, it is almost impossible to predict where and at what point on the planet there will be an earthquake tomorrow or today. All that remains is to keep track of where exactly they occur...


For today’s publication, I have selected three of the best services with which you can find out where there was an earthquake today or in the previous day (week, month, etc.), what strength it was, where its epicenter is, etc. In general, get access to almost the same information , which is owned by geologists all over the world.

Online earthquake map

This map displays the most complete information on seismic activity from all major geological sources. You can change its scale by holding down the CTRL key and turning the mouse wheel, switch between display modes in the form of a map or from a satellite:

The advantage of this map is that it collects specific numerical statistics in the form of graphs on tremors around the world:

  • Quantity per day
  • Time distribution
  • Maximum magnitude by day

And in the table, data is updated online (the most recent at the top) for all earthquakes in the world, indicating their characteristics and data source.

Online monitor of the planet's seismic activity

The website https://earthquake.usgs.gov/ was created thanks to the support and participation of the United States Geological Survey (USGS), the US Geological Survey. The goal of this project is to save lives by providing the most up-to-date information about earthquakes occurring not only in the United States, but throughout the world.

In the central part of the screen you see a display of our planet and circles representing the epicenters of seismic activity at the present time. On the left side of the window there is a monitor (constantly updated list) of the latest information:

  • Where did the earthquake occur?
  • At what depth
  • What time
  • What magnitude

By clicking on any event from the list in the pop-up window you will find more detailed information about it:

The size of the circles on the map and their color depend on the strength of the tremors and how long ago they occurred:

The information on the site is updated every minute (!), so you receive the most current and up-to-date information about seismic activity on Earth.

Real-time earthquake monitoring

Finally, the third resource displays the tremors occurring on Earth in real time in animated form:

Epicenters have different colors depending on the strength of the tremors (green - up to three, burgundy - more than six):

The left side of the window displays a feed of seismic events in the world (the most recent at the top). By clicking on any of them, you will move to the desired point on the world map and see the details in a pop-up window:

Everything is fine, the animation is cool and interesting, it makes the overall picture more clear, but it is precisely because of it that the site slows down quite noticeably. Perhaps it’s just me (if you haven’t had any problems with it, please write in the comments).

Earthquakes are a terrible natural phenomenon that can bring numerous disasters. 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.

Which areas of the world are most affected by earthquakes? To answer this question, you need to look at where the active seismic areas are. These are zones of the earth's crust that are more mobile than the surrounding regions. They are located at the boundaries of lithospheric plates, where large blocks collide or move apart. It is the movements of powerful rock layers that 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 major seismic belt stretches along the high young from the Alps and other mountains of 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 the Far East, the Commander and Kuril Islands, Fr. 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 other large cities are 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 and natural gas from the subsoil for their needs, pump out water, build mines for the extraction of solid minerals... And underground nuclear explosions are generally comparable to natural earthquakes in their strength.

The collapse of rock layers in itself can pose a danger to people. Indeed, in many areas, voids form directly under populated areas. 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 the correct behavior in case of a natural disaster, which will increase the chances of salvation.

Seismically active regions of Russia place special demands on both industrial and civil construction. 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.
