Volcanoes are found mainly where tectonic plates converge or diverge. The Mid-Atlantic Ridge is a point of diverging tectonic plates and contains numerous volcanoes. The Pacific Ring of Fire is a region of convergent tectonic plates and also has many volcanoes. Volcanoes can also form in regions where plate thinning or stretching occurs on the crust, such as the East African Fissure and Grande Reef in North America. The United States has more volcanoes than any other country on Earth, followed by Russia and Indonesia.
Volcanoes in the USA
The United States has the largest number of volcanoes at 173, and most of them are in Alaska, where eruptions occur almost every year. Other volcanoes are found in Hawaii, and Kilauea is the world’s most active volcano, having erupted continuously since 1983. There are about 161 active volcanoes in the USA. Most of them are on the western side of the country. Eighteen volcanoes are categorized as very high threat due to internal activity and the proximity of a large population. Five of the 18 volcanoes are in Alaska. Volcanic Mount Kilauea in Hawaii is considered the most dangerous volcano in the entire country. In general, it is in the United States that most of the most amazing volcanoes in the world are located.
Volcanoes in Russia
Russia is home to 166 volcanoes. The Kamchatka Peninsula has the largest concentration of volcanoes lying in the eastern part of Russia. There are 29 active volcanoes on the Kamchatka Peninsula. Klyuchevskaya Sopka is the highest volcanic mountain, which is located at an altitude of 4756 meters above sea level, and is the largest active volcano in the northern hemisphere. Bolshaya Udina is one of the volcanoes in Russia that was originally considered extinct, but seismic activity was recorded in 2017. No one knows when the last time the mountain erupted.
Volcanoes in Indonesia
There are about 139 volcanoes in Indonesia. Volcanoes in Indonesia are part of the Pacific Ring of Fire, and most of its eruptions in the past have resulted in damage to arable land and loss of life. Mount Merapi and Kelut are the most active volcanoes in Indonesia on the island of Java. Most of the country’s volcanoes are on the 1,800 mile long chain commonly known as the Sunda Arc. The arc is the point where subduction of the Indian Ocean plate occurs. The largest eruptions on the planet occurred in Indonesia. The eruption of Mount Tambora in 1815 is one of the largest eruptions in the world in recent history. The eruption had a huge impact on the climate in Europe in 1816. The year was called the year without summer.
Volcanoes in Iceland
Iceland is home to 130 volcanoes and most of its volcanoes are located within the Mid-Atlantic Ridge, which is a diverging tectonic plate boundary. Greenland has 30 active volcanoes, and since 874 AD. 13 volcanoes erupted. The worst eruption occurred between 1783 and 1784, which killed about a quarter of Iceland’s inhabitants. In 2010, Eyjafjallajokull erupted and a volcanic ash plume in the air blocked air travel in northern Europe for several weeks.
