What is a dormant Volcano?
A volcano is classified as active if it is erupting lava, releasing gas or generates seismic activity. A volcano is dormant if it has not erupted for a long time but could erupt again in the future. Once a volcano has been dormant for more than 10 000 years, it is termed extinct. This volcano is still a risk and that must be considered but they pose less and less of a risk the longer it has been since there is an eruption.
Examples of Dormant Volcanos:
Maurna Kea, in Hawaii:
Mauna Kea is a dormant volcano in the Hawaian Islands. It is the highest point in Hawaii at 4,205 meters. If measured from top to bottom, below sea level, it is 10,200 meters high and would be the tallest mountain in the world. It is around 1,000,000 years old. Mauna Kea means 'white mountain' because in winter it often has snow at the summit.

Mount Edziza in Canada:
Mount Edziza is a dormant volcano located 38 km southeast of Telegraph Creek, Canada. It is situated in an area with potentially active volcanoes in the Stikine Volcanic Belt. It is a shield volcano that began erupting roughly 10 million years ago and continued to actively erupt until about 1,340 years ago.
Edziza is made up of a lot of cinder cones and blocky lava flows that still keep their first forms, this is the second largest area of volcanic activity in the northern Stikine Volcanic belt, as well as in Canada.

Mount Rainier in the United States:
Mount Rainier is a mountain 87 kilometers southeast of Seattle Washington, in the United States. The volcano is the highest mountain in the Cascade Range, at 4,392 meters. The top of the mountain is mostly covered by snow and glaciers. Rainier is technically an active volcano but has not had an eruption for more than 100 years. Some describe Rainier as dormant or inactive.
