hi dear ones,
Volcanoes are those ruptures in the Earth’s surface or crust, that allows gases and hot and molten rock to escape from deep below the surface. Most volcanic activity forms mountains or mountainous regions over a period of time.
Supervolcanoes: Supervolcanoes produce the largest eruptions on Earth.
Volcanic Cones: Volcanic cones are the simplest types of volcanoes.
Active and Dormant And Extinct Volcanoes
- An active volcano is one that is presently erupting (or at least growling a lot, with lots of seismic and thermal activity).ALSO A volcano that is erupting or has erupted during historic times is called active.
- A dormant volcano is currently inactive, but could feasibly erupt in the future. Volcanoes that appear recent but have no recorded activity other than the quiet escape of gas are called dormant.
- An extinct volcano is one that is both inactive and unlikely to erupt again in the future. A Volcano in which there is no evidence of any activity is considered extinct.
List of Active Volcanoes:
Mount Aso is one of the largest active volcanoes from those seen all over the world. This active volcano is located in Japan, on the island of Kyūshū.

The Fourpeaked Mountain is located in Alaska. Previously considered to be a dormant volcano, Fourpeaked Mountain recently started showing signs of volcanic eruption in September, 2007. Although there may have been no major eruptions till date, one has always noticed a mild steam emanating from the summit of the Fourpeaked Mountain.
The Hekla volcano is located in the Southern area of Iceland. This volcano is reputed to be Iceland’s most active volcano. Hekla has recorded a series of eruptions since the earliest recorded in 1104. The last eruption was known to have been recorded in the 2000.
The Irazú Volcano is located in Costa Rica. Recently, the Irazú Volcano has shown signs of volcanic activity for the past couple of years. The year 1994 witnessed a small eruption. Prior to this, the Irazú volcano had erupted frequently in the olden days.
The Mayon volcano is located in the Philippines. This active volcano is categorized by the conical shape. Records have shown that this volcano has had around 47 eruptions in the past few years. It is the perfect symmetry of this volcano, which is perhaps why, it is also known as the world’s most perfectly formed volcano.
This volcano is located to the south of Managua in Nicargua. Experts have seen large amounts of sulphur dioxide gas being emitted from the Mayasa volcano. Explosions have occurred during the past few years that have propelled rocks 500 m from the crater. The last recorded eruption of this volcano happened in the year 2005.
