Volcanoes can fascinate and terrify at the same time, and each eruption is extraordinary and terrifying at the same time. Volcanoes have been fascinating and feared for centuries. What is worth knowing about them?

Volcano eruption

How a volcano erupts? A volcano is nothing more than a hole in the Earth through which a mixture of gases, ash, water vapor and lava - liquid rock is ejected into the atmosphere. Many volcanoes are located under the sea, many of them can be seen in different parts of the world. They are usually in the shape of a high cone with a crater at the top. Many of the islands, today enjoying their idyllic atmosphere, are in fact underwater volcanoes, which not so long ago aroused fears.

The satellite weather map shows the formation of volcanic ash close to active volcanoes.

Many volcanoes are relics from hundreds or even thousands of years ago, but it is worth noting that new volcanoes are constantly appearing on our planet. An interesting example can be seen in Mexico, where the volcano was formed in the 1940s.

An underwater volcano eruption in 2022 in the Pacific Ocean near the Tonga Islands caused a tsunami and covered nearby islands with volcanic ash. Shockwave recorded all over the world.

Where do volcanoes appear? 

Usually where the earth's crust is weaker, which means that dust, water vapor and lava can pass through it. There are also volcanoes that form in places called hot spots. These are the points where (due to high temperature) excess magma is formed, which penetrate towards the Earth's surface and, over time, break through its crust. A good example of such a place can be the volcanoes in the Pacific, from which the present-day Hawaiian Islands were formed.

Active volcanoes map

See on the map where the active volcanoes are. Red signifies eruptions and orange signifies low activity volcanoes. You can also check where the earthquake occurred on the map.

Volcanoes have shown their power more than once. To this day, Etna arouses admiration and fear, and the history of ancient Pompeii, destroyed by Mount Vesuvius in 79 AD, is also known. Volcanoes also gave a hard time to the inhabitants of the Philippines in 1991, and in the 1980s in Mexico. They are still an important element of the Earth's landscape, they can still pose a considerable threat to us. To date, there are around 1,300 active volcanoes on Earth that erupt regularly. About 500 volcanoes are known peaks, although most of them are found under the waters of the seas and oceans. Each of them can impress with their power, each of them is an interesting topic for researchers and scientists.
