Classification of Volcanoes: Dormant
As we go to the second classification of volcanoes, I'll just tell you that inactive volcanoes can be either extinct volcano (the one we've been tackled on the last blog) or dormant volcano, which we will be having in this blog. Get ready for we will start this lesson.

A dormant volcano is used to refer to those that are capable of erupting, and will probably erupt again in the future, but hasn't had an eruption for a very long time. Here too, definitions become complicated since it is difficult to distinguish between a volcano that is simply not active at present, and one that will remain inactive. [1]
Dormant volcanoes are the volcanoes that are quiet, but might possibly erupt again. A dormant volcano is "sleeping," but it could awaken in the future. Dormant volcanoes include those which have not erupted in the past 10,000 years [2]
All in all, a dormant volcano is an active volcano that is not erupting, but supposed to erupt again. [3]
Mauna Kea

One of the best examples of a dormant volcano is Mauna Kea, one of the five volcanoes that make up the Big Island of Hawaii. The peak of Mauna Kea is 4,207 meters above sea level, but 10,203 meters above the base of the floor of the Pacific Ocean. Geologists classify Mauna Kea in the post-shield stage of volcanic evolution. It stopped being a shield volcano about 200,000 years ago. Mauna Kea’s last eruption is thought to be 2460 BC.[4]
Mount Kilimanjaro
(https://simple.wikipedia.org/wiki/Mount_Kilimanjaro)
Kilimanjaro (or Kilima Njaro, which means "shining mountain" in Swahili), formerly Kaiser-Wilhelm-Spitze, is a mountain in northeastern Tanzania. Kilimanjaro is the tallest free-standing mountain rise in the world, rising 4600 meters (15,000 ft) from the base, and includes the highest peak in Africa at 5,895 meters (19,340 ft). It gives a dramatic view from the surrounding plains. Almost 85 % of the ice cover on Kilimanjaro disappeared from October 1912 to June 2011.
Kilimanjaro is also a strato-like volcano. It has explosive eruptions. The last major eruption was about 100,000 years ago. [5]
Mount Ararat
(https://en.wikipedia.org/wiki/Mount_Ararat)
Mount Ararat is a snow-capped and dormant compound volcano in the extreme east of Turkey. It consists of two major volcanic cones: Greater Ararat, the highest peak in Turkey and the Armenian plateau with an elevation of 5,137 m (16,854 ft); and Little Ararat, with an elevation of 3,896 m (12,782 ft). The Ararat massif is about 40 km (25 mi) in diameter. Despite the scholarly consensus that the "mountains of Ararat" of the Book of Genesis do not refer to specifically Mt. Ararat, it has been widely accepted in Christianity as the resting place of Noah's Ark. It is the principal national symbol of Armenia and has been considered a sacred mountain by Armenians. It is featured prominently in Armenian literature and art and is an icon for Armenian irredentism. Along with Noah's Ark, it is depicted on the coat of arms of Armenia. [6]
