Despite their lethality, various volcanoes have long attracted people to themselves. Previously, people were attracted by fertile soils, enriched with minerals and trace elements due to the activity of volcanoes, now tourists are attracted by the beauty and majesty of these natural sites.

Where are the largest volcanoes on the world map?

Most of today's active volcanoes are located in Pacific volcanic ring- the area in which the largest number of eruptions and 90% of earthquakes occur on our planet.

The second most powerful seismic zone is the Mediterranean fold belt, stretching from the Indonesian islands to.

Strongest eruption in history

The most destructive eruption in its consequences is considered to be the catastrophe that occurred in 1883 during the explosion. volcano Krakatoa located in. During this cataclysm, more than 36 thousand people died, more than 165 cities and villages were completely destroyed, ash was thrown to a height of 70 kilometers.

The force of the explosion during the eruption exceeded the force of the explosion of a nuclear bomb over Hiroshima by 10 thousand times. Most of the deaths are the result of huge tsunami caused by the eruption. The island on which Krakatoa was located was almost completely destroyed during the disaster. The sound from the explosion spread to a distance of 5 thousand kilometers from the epicenter of the disaster.

Earth's greatest active volcanic mountains

The largest active volcanoes in the world in terms of volume:

• Mauna loa, Hawaii, with a volume of 80 thousand cubic kilometers;
• Kilimanjaro(Tanzania), which is considered dormant but has the potential to start activity, has a volume of 4,800 cubic kilometers;
• Sierra Negra volcano located in the Galapagos Islands (Ecuador) has a volume of 580 cubic kilometers.

Which country has the largest lava source?

In terms of its size, there is no equal to the Hawaiian volcano Mauna Loa, which has a volume of 80 thousand cubic kilometers. The title of the highest is contested by 2 volcanoes from South America:

1. Llullaillaco located on the border of Argentina and Chile with a height of more than 6 thousand meters;
2. Cotopaxi located in Ecuador with a height of 5897 meters.

Description with titles

There are from 1000 to 1500 active volcanoes on our planet. Many of them are located near densely populated areas and pose a threat to human life. The most dangerous volcanoes, which are under special supervision, are included in List of Volcanoes of the UN Decade.

Merapi

Merapi, which translated from Indonesian means "Mountain of fire", recognized as one of the most dangerous volcanoes in Asia. It is located in the south of the island of Java in Indonesia, and its peak rises to a height of 3 thousand meters.

Significant eruptions of Merapi occur with a frequency of about 7 years; during its history, Merapi has repeatedly caused the death of many people. In 1930, 1400 people became victims of the eruption, and in 2010 more than 350 thousand people had to be evacuated, 353 inhabitants of the island were killed.

Near Merapi is located Yogyakarta city, in the agglomeration of which more than 2 million people live. For its activity and danger to the lives of people, Merapi is included in the list of the Volcanoes of the Decade.

Sakurajima

Sakurazdima volcano (Japan) is located on Kyushu island, its summit rises to a height of 1110 meters. The first eruption recorded by the chronicles took place in 963, and the most powerful one dates back to 1914, but thanks to the tremors preceding it, most of the local residents managed to evacuate, “only” 35 people died.

Since the middle of the 20th century, the volcano has been constantly active. Every year happen thousands of small explosions and ash emissions.

In 2013, there was a large ash ejection, reaching an altitude of 4000 meters.

Sakurajima is also on the Volcanoes of the Decade.

Aso

Volcano Aso is also located on Kyushu island in Japan. The highest point of Aso is located at an altitude of 1592 meters. During the observation of the volcano, there were about 165 large and medium eruptions, many of which resulted in human casualties.

The last time people died as a result of volcanic eruptions in 1979, when 3 people died and 11 were injured. But Aso is dangerous not only for its eruptions, poisonous vapors of volcanic gas regularly poison tourists who are trying to conquer Aso. The last such incident occurred in 1997, when two climbers were killed.

The last eruption of Aso was noted in 2011; ash was emitted to a height of up to 2 kilometers.

Nyiragongo

Nyiragongo is in the territory DR Congo in the Virunga mountain system (Africa). In the crater of the volcano is the world's largest lava lake, the depth of which can reach 3 kilometers. In 1977, a crater wall ruptured, resulting in a large lava runoff into the surrounding area, resulting in the death of 70 people.

During observations of Nyiragongo since 1882, it was recorded 34 major volcanic eruptions... A feature of the eruptions of Nyiragongo is the extremely fast flow of lava, reaching a speed of 100 kilometers per hour. During a major eruption in 2002, 400,000 residents of the city of Goma, located near the volcano, were evacuated. Nevertheless, 147 of them died as a result of this cataclysm, and the city itself received significant damage.

All these factors make Nyiragongo one of the the most dangerous volcanoes on the planet, for which he was rightly included in the list of Volcanoes of the Decade.

Galeras

Volcano Galeras is located in Colombia near the town of Pasto, which has a population of over 400 thousand people. Its height is over 4200 meters. Because of its danger, Galeras was included in the list of the Decade Volcanoes that pose the greatest threat in the foreseeable future.

It is believed that over the past 7000 years, Galeras has experienced at least 6 major eruptions, in 1993 the last of them was recorded.

Mauna loa

The Mauna Loa volcano is located on Hawaiian Islands belonging to the United States of America. This giant volcano covers more than half of Hawaii's area, with a peak height of 4169 meters above sea level, but most of the volcano is located under water. Together with the underwater part, its height from the base to the top reaches 9170 meters, which exceeds the height of Everest.

The eruptions of Mauna Loa occur according to the so-called Hawaiian type with the outpouring of lava, but without explosions and large ash emissions. Observations of the volcano have been conducted only since 1832, but during this time, 39 major eruptions of Mauna Loa have been recorded. This volcano was included in the list of Volcanoes of the Decade due to the huge lava flows accompanying the eruption and the densely populated area in its immediate vicinity.

The top of the volcano and its slopes are included in the list UNESCO World Heritage Site.

Colima

The most active volcano in Central America is located in the state of Jalisco. Thanks to her activity, Colima received the nickname "Little Vesuvius", its height exceeds 3800 meters.

Over the past 450 years, more than 40 large and medium volcanic eruptions have been recorded, the last of which occurred on September 12, 2016. More than 400 thousand people live near Colima, which makes it the most dangerous volcano in America... For this reason, the volcano was listed as a Volcano of the Decade.

And you will learn about the largest cities in the world in - the most populous, the longest and others.

Vesuvius

The most famous volcano in the world is located on the Apennine Peninsula in. The lonely peak of Vesuvius, 1281 meters high, rises above the vast fields of the Campania province and is part of the Apennine mountain system.

Located just 15 kilometers from Naples, Vesuvius has repeatedly entered history with its catastrophic eruptions, only large ones were recorded about 80. In 79 AD, the most destructive eruption of Vesuvius during which famous cities died:

• Pompeii;
• Oplontis;
• Herculaneum;
• Stabia.

It is believed that at least 16 thousand people died during this cataclysm.

In 1944, the last eruption of Vesuvius occurred at the moment, during this natural disaster, cities were destroyed Weight and San sebastiano, 27 people became victims. Since then, Vesuvius has not shown strong activity, but the danger of a new eruption always remains. Vesuvius is one of the main attractions of the Campania province and its visit is included in the excursion tour when traveling to Naples.

Etna

Another famous volcano in Italy is located in the east of the island of Sicily and is highest volcano, rising to a height of 2329 meters. Etna eruptions are observed several times a year. Several large eruptions of this volcano have been recorded in history, which led to devastating consequences:

1. Destroyed in 122 AD Catania city;
2. In 1169, during a large-scale eruption, Etna died 15 thousand people;
3. In 1669 Catania suffered again, houses were destroyed 27 thousand people;
4. In 1928, the ancient Mascali city.

Despite the danger of the volcano, the inhabitants of the island continue to settle on its slopes. The reason for this is fertile soil enriched with minerals and trace elements contained in cooled lava flows and ash.

Etna is one of the main natural attractions of Sicily; tourists from all over the world come to see the volcano and climb to its top.

Popocatepetl

Volcano Popocatepetl, or El Popo, as the locals affectionately call it, is located in Mexico, 70 kilometers from the capital of this country, Mexico City. The height of the volcano is almost 5500 meters. Over the past 500 years, Popocatepetl has erupted more than 15 times, with the last occurring as recently as 2015. An extinct volcano is located near Popocatepetl Istaxihuatl.

A trip to these volcanoes is an integral part of the excursion program when visiting Mexico City.

Klyuchevskaya Sopka

The highest volcano in Eurasia is located on the Kamchatka Peninsula and is considered the most famous of the many volcanoes in Kamchatka. The highest point outside the Caucasus Mountains reaches an altitude of 4750 meters. It is the most active volcano in Eurasia, on average, its eruptions occur almost annually... The last significant eruption occurred in 2013, the height of the ash ejection was 10-12 kilometers. The eruption was accompanied by mud streams and ash falls.

Cotopaxi

The active volcano Cotopaxi is located in South America on the territory of the state Ecuador as part of the Andes mountain system. The height of the Cotopaxi summit is 5897 meters. In the entire history of observations, 86 eruptions were recorded, the largest one leading to the complete destruction of the city of Latacunga in 1786. The last activity of Cotopaxi was noticed in 1942, after which the volcano is still dormant.

Famous extinct giants

In addition to active volcanoes, there are many extinct volcanoes on our planet that do not exhibit volcanic activity.

Supreme

The highest extinct volcano on the planet, Aconcagua, is located in Argentina and is part of the Andes mountain range. Aconcagua is not only the tallest extinct volcano in the world, but also the highest peak in America, the Western and Southern Hemispheres. The height of Aconcagua exceeds 6950 meters.

Sleeping giants

Many extinct volcanoes are now considered just mountains, although some of them can potentially "wake up" and begin to show activity. Such volcanoes, which may become active in the future, are called "Sleeping".

• Famous Mount Kilimanjaro in Tanzania (Africa) it is a dormant volcano that is not active. Scientists believe that one day Kilimanjaro may wake up, then this potential volcano will become one of the highest in the world, because the height of Kilimanjaro is 5895 meters above sea level.

Colossal supervolcano Yellowstone was considered extinct, but scientists have found that it shows little activity, so now Yellowstone is classified as a dormant volcano. The last time the giant erupted was almost a million years ago.

It is believed that if Yellowstone wakes up, a potential eruption will become one of the largest disasters in the history of the Earth, every third inhabitant of the planet will die, and several US states will be completely destroyed.

Yellowstone eruption will provoke many earthquakes, giant tsunami waves and eruptions of other volcanoes, which will affect almost every inhabitant of the planet. The ash ejected by the volcano will cover the earth's surface from the sun for a year and a half, and a volcanic winter will come throughout the planet.

However, not all scientists believe that the consequences of this cataclysm will be so serious. In any case, the eruption of this volcano remains one of the main potential threats to humans.

• The largest extinct volcano in Russia - 5642 meters. It is located on the border of the republics of Kabardino-Balkaria and Karachay-Cherkessia. Belongs to the list of the highest peaks in the six parts of the world. Scientists consider the activity of the volcano not so much complete as fading.
• The largest volcano of our time cannot be visited and is very difficult to see, since it is under water. Array Tamu is located at the bottom of the Pacific Ocean and is located approximately 1,600 kilometers east of the Japanese Islands. Its dimensions are 650 by 450 kilometers; in terms of its scale, the massif is one of the largest not only on Earth, but also in the entire solar system. The last volcanic eruption occurred 140 million years ago.
• Dormant volcanoes Big and Small Ararat are now located on the territory and belong to the category of volcanoes that do not show volcanic activity. The top of Mount Big Ararat, reaching 5165 meters, is the highest point in Turkey.
• One of the highest peaks of the Caucasus, Mount Kazbek is also an extinct volcano. Kazbek is located on the border with Russia, the highest point of the mountain is located at an altitude of more than 5 kilometers. During research in one of the caves of Kazbek, volcanic ash was found from an eruption that supposedly occurred 40 thousand years ago.

Do you like extreme tourism to trembling knees? If so, then the most terrible places on Earth are revealing their secrets to you.

Watch a video about these and other volcanoes in the world:

Volcanoes- geological formations on the surface of the earth's crust, through which magma appears. The name comes from the Roman god of fire - Vulcan. Today there are over 1000 active volcanoes on the planet. Further we will introduce you to the classification of volcanoes, tell you where most of them are located and which are considered the highest and most famous.

Volcanoes: interesting facts

There is a large classification of volcanoes. So that's all volcanoes of the world are divided into 3 types:
By type (thyroid, stratovolcanoes, cinder cones, domed);
By location (sub-summer, ground, underwater);
By activity (extinct, sleeping, active).

Each volcano consists of the following parts:
Main crater;
Side crater;
Vent.


Some volcanoes do not erupt lava. There are also mud volcanoes, and geysers are also post-volcanic formations.

Where are the volcanoes of the world

Most of the volcanoes are located in the Andes, Indonesia, Iceland, Hawaii and Kamchatka. However, they are not located chaotically, but in strictly defined zones:
Most of the volcanoes are located in an area called the Pacific Volcanic Ring of Fire: in the Andes, Cordillera, Kamchatka, as well as the Philippines and New Zealand. Almost all are located here active volcanoes the world from the terrestrial - 328 out of 540.
Another location zone is the Mediterranean fold belt, which includes the Mediterranean Sea (Santorini, Etna, Vesuvius) and stretches to Indonesia, where almost all the powerful eruptions of the world took place: Tambor in 1815 and Krakatoa in 1883.
The Mid-Atlantic Ridge, which forms entire volcanic islands. Notable examples are the Canary Islands, Iceland.

Active volcanoes in the world

Most of the active volcanoes are located in the above zones. Volcanoes often erupt in Iceland, the highest volcano in Europe, Etna, periodically reminds of itself. Others that are particularly well known:
Popocatepetl, located near Mexico City;
Vesuvius;
Mauna Loa;
Nyiragongo (DR Congo), famous for its huge lake of boiling lava located in the crater.

Extinct volcanoes of the world

Volcanoes often complete active eruptions. Some of them are considered extinct, others are considered dormant. Extinct volcanoes of the world located throughout the planet, including in the Andes, where the highest volcano in the world is located - (6893 meters), as well as the volcanic mountain of Aconcagua (the main peak of South America).

Often extinct volcanoes used as observatories, for example, Mauna Kea in the Hawaiian Islands, in the crater of which 13 telescopes are installed. By the way, it is Mauna Kea that is recognized as the highest volcano in general, if you count the underwater part, then its height is 10 205 meters.

The most famous volcanoes in the world

Everyone has heard stories about terrible eruptions that destroyed entire cities and destroyed islands. Here we will tell you about:
Vesuvius, this small volcano in Italy (1281 m) destroyed the city of Pompeii. This moment is even captured in Bryullov's painting "The Last Day of Pompeii".
Etna is the highest volcano in Europe, which periodically erupts. The last eruption took place in May 2015.
Krakatoa is a volcano in Indonesia, the eruption of which in 1883 was equal to the explosion of 10,000 atomic bombs. Now in its place rises a new volcano - Anak-Krakatau.
Tambor. In 1815, the most powerful eruption of our time took place, as a result of which a volcanic winter (pollution of the atmosphere with ash) began, and 1816 became a year without summer.
Santorini, which destroyed the Minoan civilization and destroyed an entire island in the Mediterranean.
Mont Pele in Martinique, which destroyed the port of Saint Pierre in a matter of minutes. Killed 36,000 people
The Yellowstone Caldera is a potential supervolcano whose eruption could change the map of the world.
Kilimanjaro is the highest point in Africa.

An interactive map of active (active) volcanoes allows you to see the degree of volcanic activity, the danger of eruptions, as well as the likelihood of eruptions online. The map is designed to help travelers and explorers who are going to visit a particular region of the world. Plan your expeditions with threats and disasters in mind.

List of active volcanoes in the world

Today we will take a look at where there are active volcanoes in the world. Most of them are located along the coast. This area is called the Pacific Ring of Fire. The second most volcanic zone is the Mediterranean belt.

There are about 900 active volcanoes on land.

About 60 geological formations of the earth explode every year. Consider the most dangerous of the active, as well as some of the impressive, but sleeping.

Merapi, Indonesia

Merapi is the most imposing, nicknamed "The Mountain of Fire". It is located on about. Java, reaches a height of 2914 m. Every 7 years, large-scale emissions are carried out, twice a year - small ones. Smoke is constantly coming out of its crater. One of the most significant tragedies associated with activity took place in 1006. Then a fierce element destroyed the Javanese-Indian state of Mataram.

In 1673, another powerful eruption broke out, as a result of which the towns and villages located at the foot were destroyed. In 1930, volcanic outbursts caused the death of 1,300 people.

The last release of Merapi occurred in 2010, when 350 thousand people had to be evacuated. Some of them decided to return and died in the lava flow. Then 353 people were injured.

In that last disaster, the Fiery Mountain threw out a mixture of ash and gas at a speed of 100 km / h, while the temperature reached 1000 ° C.

Sakurajima, Japan

Sakurajima is located on about. Kyushu. Once the mountain stood separately, but in one of the eruptions with the help of lava it joined the Osumi Peninsula. It rises to a height of 1117 m. It consists of three peaks, the highest of which is the northern one.

Sakurajima's activity increases every year, and until 1946 there were only 6 emissions. Since 1955, it has been erupting constantly.

Note: one of the largest disasters occurred in 1914, when 35 people were killed. In 2013, 1,097 emissions of insignificant force were recorded, and in 2014 - 471.

Aso, Japan

Aso is another volcanic giant about. Kyushu. Its height is 1592 m. It is a caldera, in the middle of which there are 17 cones. The most active of them is Nakadake.

Aso last spewed lava in 2011. Since then, about 2500 aftershocks have occurred here. In 2016, the ejection process was accompanied by an earthquake.

Its useful to note: Despite the danger associated with the extreme activity of Aso, about 50 thousand people live in the caldera, and the crater itself has become a popular object of active tourism. In winter, skiing is available on the slopes of Aso.

Nyiragongo, Republic of the Congo

Nyiragongo belongs to the Virunga mountain system and is the most active in Africa. The height is 3470 m. In its crater there is a huge seething lava lake, the largest in the world. During an eruption, lava flows out almost completely, destroying everything around in a matter of hours. After that, it fills the crater again. Due to the military situation in the Republic of the Congo, the crater has not yet been sufficiently explored.

Since the end of the 19th century alone, 34 eruptions of the formidable Nyiragongo have been recorded. Its lava is very liquid because it does not contain enough silicates. For this reason, it spreads rapidly, reaching a speed of 100 km / h. This feature makes Nyiragongo one of the most dangerous on the planet. In 1977, a huge mass of lava hit a nearby town. The reason was the rupture of the crater wall. The catastrophe claimed the lives of several hundred people.

In 2002, another large-scale eruption occurred, then 400 thousand people were evacuated, 147 of whom died. Despite the fact that this Nyiragongo is considered the most dangerous in the world, about half a million people live in the nearby settlements.

Galeras, Colombia

It rises above the Colombian town of Pasto, with about 500 thousand inhabitants. Galeras reaches a height of 4276 m. In recent years, Galeras has been constantly active, throwing out volcanic ash.

One of the largest eruptions was recorded in 1993. The disaster led to the death of 6 volcanologists and 3 tourists in the crater. The catastrophe came unexpectedly, after a long lull.

One of the recent eruptions occurred in August 2010. Colombian authorities periodically evacuate local residents as Galeras is active.

Colima, Mexico

Colima is located on the Pacific coast. Consists of 2 peaks, one of which is extinct. In 2016, Colima revived, releasing a column of ash.

The last time he reminded of himself was on January 19, 2017. At the time of the catastrophe, a cloud of ash and smoke rose 2 km.

Vesuvius, Italy

Vesuvius is the most famous volcanic giant in continental Europe. It is located in Italy, 15 km from.

Vesuvius has 3 cones. Strong eruptions alternate with periods of low-intensity activity. Throws out a huge amount of ash and gases. In 79, Vesuvius shook all of Italy, destroying the cities of Pompey and Stabia. They were covered with a thick layer of ash, reaching up to 8 m. The city of Herculaneum was flooded with mud streams, since the eruption was accompanied by mud rains.

In 1631, an eruption was noted, which claimed the lives of 4,000 people. It turned out to be weaker than in 79, but the slopes of Vesuvius have since been inhabited by a larger number of people, which led to such casualties. The volcano after this event became lower by 168 m. The eruption of 1805 destroyed almost all of Naples and claimed the lives of 26 thousand people.

Vesuvius last erupted in lava flows in 1944, razing the cities of San Sebastiano and Massa. The number of victims was 27 people. After that, the volcano died down. A volcanological observatory was built here to track his activities.

Etna, Italy

Etna is the highest volcano in Europe. It is located in the northern hemisphere in the east of Sicily. Its height changes after each eruption, now it is equal to 3429 m above sea level.

Etna has, according to various estimates, 200-400 side craters. Every 3 months, one of them erupts. Quite often, this leads to the destruction of the villages that are spread out nearby.

Despite the dangers, the Sicilians densely inhabit the slopes of Etna. They even created a national park here.

Popocatepetl, Mexico

The second highest peak in Mexico, its name means "smoking hill". It is located 70 km from Mexico City. The height of the mountain is 5500 meters.

Popocatepetl has erupted over 15 times in 500 years, most recently in 2015.

Klyuchevskaya Sopka, Russia

This is the highest peak in Kamchatka. Its height ranges from 4750-4850 m above sea level. The slopes are covered with side craters, of which there are more than 80.

Klyuchevskaya Sopka reminds of itself every 3 years, each of its activities lasts several months and is sometimes accompanied by ash falls. The most active year was 2016, when the volcano exploded 55 times.

The most destructive was the catastrophe of 1938, when the activity of Klyuchevskaya Sopka lasted for 13 months.

Mauna Loa, Hawaii, USA

Mauna Loa can be found in the central part of the island of Hawaii. It rises 4169 m above sea level. Mauna Loa belongs to the Hawaiian type.

Its characteristic feature is the outpouring of lava, passing without explosions and ash emissions. Lava erupts through a central vent, cracks and fractures.

Cotopaxi, Ecuador

Cotopaxi belongs to the Andes mountain range. It is the second highest peak, rising to 5911 m.

The first eruption was recorded in 1534. The eruption had the most devastating consequences in 1768. Then the release of lava and sulfur was accompanied by an earthquake. The catastrophe destroyed the city of Latacunga and the surrounding area. The eruption was so strong that traces of it were found in the Amazon basin.

Iceland

There are about three dozen volcanoes on the island of Iceland. Among them there are already extinct ones, but there are also active ones.

This island is the only one in the world with so many geological formations. Icelandic territory is a real volcanic plateau.

Extinct and dormant volcanoes

Volcanoes that have lost their activity are extinct and dormant. It is safe to visit them, which is why these sites are more popular with travelers. On the map, such geological formations are marked with black asterisks, in contrast to the existing ones, marked with red asterisks.

What is the difference between an extinct and a dormant volcano? The extinct have not been active for at least 1 million years. Presumably, their magma has already cooled down and will not be able to explode. True, volcanologists do not exclude that a new volcano may form in their place.

Aconcagua, Argentina

Aconcagua is the highest peak in the Andes. It rises to 6960.8 m. A mountain was formed at the junction of the Nazca and South American lithospheric plates. Today the slopes of the mountain are covered with glaciers.

Aconcagua is of interest to climbers as the highest peak in South America, as well as the highest extinct volcano.

Kilimanjaro, Africa

If someone is asked to name the highest mountain in Africa, he will name it - the most famous mountain on the African mainland. Consists of 3 peaks, the highest of them is Kibo (5,891.8 m).

Kilimanjaro is considered asleep, now only gases and sulfur are escaping from its crater. It is expected to be active when the mountain collapses, leading to a massive eruption. The most formidable scientists consider the peak of Kibo.

Yellowstone, USA

Yellowstone is located in the national park of the same name. The summit is one of the supervolcanoes, of which there are 20 on Earth. Yellowstone is extremely dangerous because it erupts with incredible force and can affect the climate of the planet.

Yellowstone has erupted three times. The last eruption took place 640 thousand years ago, at the same time the caldera depression was formed.

At this volcano, lava accumulates in a special reservoir, where it melts the surrounding rocks, becoming thicker. This reservoir is very close to the surface, which worries volcanologists.

The eruption is stopped by streams of water that cool the magma bubble and burst outward in the form of geysers. Since there is still a lot of energy left inside the bubble, it is expected to burst out in the near future.

The US authorities are taking all measures to prevent the eruption of Yellowstone, because it can kill 87 thousand people. One of the projects is the installation of a geothermal station, but this will require drilling wells that can provoke a disaster not only in the country, but throughout the planet.

Elbrus, Russia

The Caucasus peak is attractive for climbers today. Its height is 5621 m. It is a dormant formation in which volcanic processes take place. The last eruption took place supposedly 1.7 thousand years ago, 500 years ago, he released a column of ash.

The activity of Elbrus is evidenced by the geothermal springs located nearby. Scientists disagree on when to expect the next eruption, but it is known for sure that it will cause the mudflow to converge.

Big and Small Ararat, Turkey

Big Ararat (5165 m) is located on the Armenian Highlands, 11 km from it is Small Ararat (3927 m).

The eruptions of Big Ararat have always been accompanied by destruction. The last tragedy broke out in 1840 and was accompanied by a strong earthquake. Then 10,000 people died.

Kazbek, Georgia

Kazbek is located in Georgia. Locals call it Mkinvartsveri, which translates as "ice mountain". The height of the giant is 5033.8 m.

Kazbek is not active today, but he belongs to the potentially dangerous. It last erupted in 650 BC.

The mountain has very steep slopes, mudslides are possible.

Conclusion

Volcanoes are among the most attractive tourist sites. Today they are no longer so dangerous, since their activity can be predicted by volcanologists. Research is being conducted on the use of the energy of geological formations for the benefit of mankind.

In an effort to go to the top of a volcano, especially an active one, it is necessary to collect information about its condition, listen to the forecasts of seismologists, since tragic cases among tourists often occur.
