VESUVIUS - ITALY
It's the largest active volcano in Europe situated on land. It proudly dominates over the panorama of Naples, rising to a height of 1,128 metres above sea level. The last large eruption of Vesuvius took place in 1944, but many experts believe that it might still have more to say. A reminder of its strength is the "frozen city" - the ruins of Pompei, which was destroyed by the volcano in the times of the Roman Empire, which contains human bodies mummified in volcanic ash.
In the South of Iceland there's a volcano which, though perhaps not the largest volcano in the world, is very active. Despite its name being extremely difficult to pronounce, it was on everyone's lips in the spring of 2010. About 3,000 small cave-ins of earth preceded a discharge of gases and volcanic ash, which, for several weeks, hindered the movement of airplanes in North-Western Europe. The cities of Fljotshlia and Markadfljot were evacuated. There were no human victims of the eruption.
ERTA ALE, ETHIOPIA
The most active volcano in Ethiopia is also one of the most interesting products of nature in the world - it contains not only one, but two lakes of lava. It reaches a height of 613 metres above sea level, and its name is translated as "Smoking Mountain". It is very dangerous. An eruption in 2005 killed huge herds of livestock and forced people living nearby to evacuate the area.
Among the 150 volcanoes of Indonesia, 127 are active. Many of them, including popular Bromoand powerful Merapi, contain popular peaks for trekking. Tourists travelling to Bali also often visit Kawah Ijen, located in nearby Java. Its exceptionality is proven by a crater filled with an acidic, turquoise-hued lake, one kilometre in width, as well as impressive layers of smoking sulphur which is carried from the peak in huge baskets by workers.
This volcano with three peaks, the tallest of which is 1,117 metres above sea level, arose about 13,000 years ago, creating an island near the southern shore of the island of Kyushu. At the beginning of the 20th century, it grew tired of being isolated - a huge eruption of lava formed an isthmus, which turned the island into a peninsula. The volcano has been constantly active for nearly 50 years. In 2013 it spewed into the air 5,000 cubic metres of ash, covering the nearby city of Kagoshima.
MOUNT CLEVELAND, ALASKA
We've been hearing a lot this volcano lately. Over ,the past 230 years, Cleveland has exploded at least 22 times, and it has been the most active in the past five years. It reaches a height of 1,730 metres above sea level, and, due to the spewing of ash, it is constantly avoided by airplanes flying over the Northern Pacific. It is also the most difficult volcano to study, since there's no land road leading to it and the constant threat of eruption means it can only be admired from afar.
El Popo, otherwise known as Don Goyo, which looks like a huge (5,426 metres above sea level) cone-shaped mountain, is a volcano with a snowcapped summit located southeast of the capital city of Mexico. It's one of the world’s most active volcanoes. Its last eruption was in 2013. At that time, it was possible to see a 3.5-kilometre cloud of ash and steam rising above the crater. Its previous eruption was in 2000, when it was necessary to evacuate tens of thousands of people.
