Olympus Mons – Highest peak of the Solar System

Olympus Mons – An extinct volcano on the Red Planet, rises almost 22 km! However, the issue of measurement is contentious. So depending on where we measure the vertex. It can grow up to 26 km.

Its diameter is also impressive – at the base it is 624 km.

The volcanic crater itself is about 85 km long, 60 km wide, and up to 3 km deep. However, future Martian climbers will not be particularly delighted. Because Olympus has a gentle, 5-degree slope.

Impressive sizes can also boast:

Rheasilvia, huge impact crater with a diameter of 505 km. Covering up to 90% of the West’s asteroid surface (22.5 km high).
Series of almost even peaks on the Saturn’s moonIapetus, (approx. 20 km). And South Boösaule, the highest hill on Jupiter’s moon – Io (approx. 18 km).

Most dangerous volcanoes – Still unpredictable

Most dangerous volcanoes – Eruptions of volcanoes in ancient times were considered a divine punishment. Today, we know their causes, but they are still unpredictable. And they leave terrible havoc after themselves. Volcanoes that sow the greatest destruction and thus are the most dangerous for Earth.

Mount Etna – Italy, Sicily


  • Location: Italy, east coast of Sicily
  • Peak: 3350 m a. s. l.

Mount Etna – Is the highest active and the second most powerful volcano in Europe. It lies on the east coast of the island of Sicily, near the cities of Messina and Catania. The age of the volcano is estimated at 700,000 years. The mountain changed with subsequent eruptions, its present appearance was formed about 5000 years ago. Its height is not constant – in 1981 Etna measured 21 meters more. The reduction was caused by eruption and lava flow.

Etna’s volcanic activity is the longest documented of all volcanoes. The oldest eruptions took place in antiquity (135 A.D.). The ancient Greeks called the volcano Mount of Fire and were convinced that one of the Titans was buried beneath. The explosions were meant to mean that he was trying to escape. The most powerful explosion occurred in 1669. When the lava got to Catania, which it partially destroyed. The potential danger lies in the fact that the volcano is located in a densely populated area.

From the beginnings of written historical sources, we know in total about 140 Etna explosions. The most devastating eruption in 1669 was preceded by a three-week earthquake. The volcanic eruption lasted four months.

The Etna volcano explodes on average once every 1.7 years.

Nyiragongo – Congo


  • Location: Congo
  • Peak: 3470 m a. s. l.

Nyiragongo volcano is located in the Virunga mountain chain and although its side craters are already extinct, the main one is one of the most active in the world. This stratovolcano is formed by a group of several volcanoes at Lake Kiwu. In the crater there is a huge lava lake, still active. The temperature of the lava located there varies between 800 and 950 ° C, has a thin consistency and flows very quickly. For this reason, the volcano is a constant threat to the surrounding cities.

The most horrible eruption took place in 1977, when lava flowing down the mountainside killed thousands of people. Magma got to the city of Goma, in which she destroyed 15% of the building and killed about 150 people. A stream of lava reached the shore of Lake Kiwu, forming a peninsula. Another volcanic eruption took place in 2002.

According to legends told by local citizens, Nyiragongo is a holy mountain. The natives believe that an enchanted spirit lives on it, which is trying hard to get out of its earthly dungeon. His angry scream explodes in the form of lava geysers and dense fogs.

Kilauea – United States of America, Hawaii


  • Location: United States of America, Hawaii
  • Szczyt: 1247 m a. s. l.

Kilauea is located on the Hawaiian island of Hawai’i (also known as Big Island) and is one of the volcanoes that form it. It occupies 14% of this island. The mountain, on the slope of which the lava flows, belongs to the most active volcanoes in the world. According to the Hawaiian history, it spits out lava uninterruptedly since 1983, an average of 400,000 m³ per day. The volcano was created as a result of tectonic movements of the Pacific plate. Which in 70 million years resulted in the creation of a chain of 6,000 km long submarine volcanoes.

The testimonies of the first eruptions come from 1750. However, we learn from the Polynesian myth that the mountain spit out lava much earlier. The lava flows covered the area of ​​hundreds of square kilometers and affected the appearance of the whole coast line. The indigenous islanders believe that Pele, the goddess of fire, lives on the mountain. Goddess punishes anyone who dares to steal volcanic stones. Being for her like children. A thief of such a stone can expect bad luck that will never leave him.

Locals, to the honor of the goddess Pele, perform ritual dances. According to tradition, they throw flowers and food into the volcano crater, which is to give them favor.

Nevado del Ruiz – Colombia


  • Location: Colombia
  • Peak: 5321 m a. s. l.

Nevado del Ruiz volcano, already active for around 2,000,000 years, is 130 km west of the capital of Colombia – Bogota. It has many layers of lava hardened alternately with volcanic ash and other pyroclastic rocks. The mountain is part of the volcanic massifs created by five more volcanoes covered with glaciers. Four of them are still active.

The volcano became famous thanks to its catastrophic eruption, which took place on November 13, 1985. As a result, glacier peaks of 25 km² have melted. The resulting lahars, flowing at a speed of 40 to 60 km / h, flooded the city of Armero and several surrounding villages with a layer of mud deep for 6 meters. Only in the city more than 21,000 citizens died (out of a total of 23,000). Losses reached $ 1 billion. The consequence of this catastrophe was the adoption by Colombia of security measures that should reduce the risk of death for so many people.

In September and October 2010, a gradual increase in seismic activity near the Arenas crater was noticed. Over the next four months, there were earthquakes that increased fear of further devastating eruptions.

Pico del Teide – Spain, Tenerife


  • Location: Spain, Tenerife
  • Peak: 3718 m a.s.l.

Pico del Teide volcano is located in Tenerife, which is the largest of the seven Canary Islands. The mountain lies near the north-west coast of Africa and occupies the greater part of the island’s surface. The crater’s circumference is unbelievable 48 km. Tenerife experienced its greatest eruption in 1709, when a stream of lava destroyed most of the port of Garachico and the northern coast. Magma sailed the valley for nine days. For the last time the volcano was active in 1909. When through the north-western slope of the mountain, flowed a lava river, long for 5 km.

Along the foot of the volcano spreads a very fertile lowland, which is moist and green all year long. Bananas, almonds, orange trees and vegetables are grown there. The southern slopes, on the contrary – moisture and rain almost do not know. The mountain can boast a world record – at sunrise the volcano casts a pyramid-shaped shadow, up to 200 km long. Which is undoubtedly the longest shadow in the world.

In the Stone Age people considered the volcano as the seat of the cruel god Guayot. During one of his trips to the New World, Christopher Columbus witnessed the activity of this dangerous mountain.

Krakatau – Indonesia


  • Location: Indonesia
  • Peak: m a.s.l.

Krakatau lies between Java and Sumatra, and belongs to the most dangerous volcanoes in the world. We can also find out about it in the last days when the mountain awoke. Its largest explosion occurred in 1883. When the Perboewatan crater threw away a 6 km high cloud of ash, visible from a distance of 160 km. The next eruption occurred a few months later. This time, volcanic dust has risen to 27 km. In the final phase of the eruption caused the creation of four tsunamis high at 30 meters. The sounds of the crash were heard even several thousand kilometers away. More than 36,000 people have died as a result of the explosion and tsunami. These events affected the entire planet, as a result of the explosion the average annual temperature decreased by approx. 1.2 ° C. This year, the volcano has woken up again. After the explosion, a large part of it collapsed and caused a deadly wave of tides that killed over 400 people.

Battle of Somme – The attack of French and British

Battle of Somme – The great Somme offensive planned by the French and the British. Was to finally break the German resistance and end the war within a few weeks. The decisive significance in this plan was played by a series of secret tunnels. Dug up by the whole company for months. Leading the artillery fire of German trenches, the British imperceptibly placed under enemy positions 19 explosives.

On the first of July 1916, mines under German lines almost simultaneously exploded. The largest load was broken in the earth by a crater with a depth of 21 meters and a diameter of 91 meters. Contrary to the expectations of the generals, however, the enemy forces were not destroyed. And the offensive became a deadly trap for the soldiers.

Already in the first 30 minutes of the fire from German machine guns, thousands of Britons were killed. On the first day of the attack on German positions. About 21000 British and French soldiers died. The fights continued for another five months. Consuming over a million lives. Only to get a 35-kilometer piece of the front. Approx. 10 kilometers deep into the enemy’s territory.
