Once there was a time when a volcanic eruption is considered to be a curse of God. By active volcanoes, we mean the volcanoes which are erupting or have erupted in modern times. The volcanoes live thousands of years and in that lifetime they erupt many times, however, even they are active some of them dont erupt in human lifespan. The sign of an active volcano includes unusual earthquake activity or significant new gas emissions. There are approximately 1,500 volcanoes that are active today and approximately 500 million people live near active volcanoes.
We are considering the Pacific Ring of Fire in this article because approximately three-quarters of the world’s dormant volcanos and active volcanos are here. Apart from the Pacific Rim, the most seismic region is Alpide belt that extends from Java to Sumatra through the Himalayas, the Mediterranean, and out into the Atlantic. Let us list down some of the active volcanoes in the world, according to Wikipedia,
1. BARREN VOLCANO, ANDAMAN AND NICOBAR ISLANDS
The barren volcano is situated on the Andaman Sea and lies about 138 km northeast of the territory’s capital Port Blair. The only active volcano in the chain from Sumatra to Myanmar and also the only active volcano in India. Barren Island is a part of the Indian Union Territory of Andaman and Nicobar Islands and quite popular for it’s as a Submarine emergent Volcano that lies in the subduction zone of India and Burmese plate.
The Barren Island volcano again started erupting in the year 2018 and many people from the world started to come to the island for the life experience. The area as the name suggests is a barren area uninhabited by humans and has a small population of goats in the area. Also, some species of birds, bats like flying foxes and few rodents are able to survive in these conditions.

Also, 1904 was also violent one, however, minor eruptions took place in 1940 and 2015 and the volcano is listed among the most active volcanoes in the world.
The terrain of the volcano has been devasted by the earthquakes many times and later ash blown out of the crater. The mountain has been built by the alternating flows of dark-coloured trachytic lava and falls of lighter-coloured ash. The diameter if the crater is 2,300 feet, measured from north to south and 1,650 feet, measured from east to west. The total depth is 1,200 feet and the base stands on open mountain grassland, however, the whole upper part of the mountain is covered with snow.
3. Galeras Volcano, Colombia
