Most Dangerous Volcanoes in the World

There are many volcanoes in the world. Volcanoes are a natural way that our Earth and other planes use in order to cool off. All planets are warm in their mantles. Sometimes this heat inside melts rocks and these hot rocks - magma - combining with gasses break through the crust and namely in such a way happens an eruption. Lava flows out of a volcano top. It’s really dangerous but nevertheless, eruptions hold a lot of appeal to many tourists.  Some volcanoes erupt only once or twice but some erupt many times and seem never stop.

There is no strict and commonly approved classification of volcanoes, but I will try give a list of some most dangerous volcanoes as to their explosive history and closeness to populated locality.

• Mt Vesuvius in Italy

I think you hardly find a person hasn’t heard about Mt Vesuvius. Mount Vesuvius belongs to one of the most dangerous volcanoes in the world. It’s eruption cycle is more than 20 years, the last eruption occurred in 1994. Millions of people live near it. Namely eruption of this volcano destroyed Pompei in 79 AD.

• Popocatepetl in Mexico

It is the highest active volcano in the Northern Hemisphere. In 2001 its flows travelled 8 km from the volcano itself and caused glacial melting. In 1996 its eruption killed climbers.

• Merapi in Indonesia

Merapi contains active lava, that adores producing pyroclastic flows (travell 6-10 km from the volcano and velocity of the flow is 110 km/hour). Eruptions happen once in 3-5 years. This volcano is active for already 10,000 years.

• Unzen in Japan

Unzen is not a single volcano, it is a huge complex of 3 volcanoes. It is dangerous and has already taken lives of many people and destroyed 2,000 buildings.

• Galeras in Colombia

Really dangerous one with a lot of eruptions. Took lives of tourists and scientists. Galeras is a volcano complex.
