What volcanoes have not erupted in some time but could erupt again?

What volcanoes have not erupted in some time but could erupt again?

Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.

What is it called when a volcano hasn’t erupted in a long time?

Dormant → Dormant volcanoes are volcanoes that have not erupted in a long time but are expected to erupt again in the future. Examples of dormant volcanoes are Mount Kilimanjaro, Tanzania, Africa and Mount Fuji in Japan.

What is a volcano that has erupted in the last two thousand years but not recently?

What is a dormant volcano? A volcano that has erupted in the last 2000 years but not recently. It is inactive but not extinct. It is difficult to decide whether a volcano is dormant or extinct.

What is the term used to describe a volcano that may erupt again at some time in the future?

Dormant volcano The term used to describe a volcano that is “sleeping,” or presently inactive, but may erupt again.

What makes a dormant volcano erupt?

Scientists believe the magma chambers—or reservoirs of molten rock—under dormant volcanoes are filled with sticky, viscous mush. According to current theory, it would take several hundred or perhaps a thousand years for the heat to distribute through the chamber and make the magma fluid enough to erupt.

What is an active volcano called?

An erupting volcano is an active volcano that is having an eruption… A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

Which of the following descriptions describes a dormant volcano?

A dormant volcano is an active volcano that is not erupting, but supposed to erupt again. An extinct volcano has not had an eruption for at least 10,000 years and is not expected to erupt again in a comparable time scale of the future.

What is a volcano that is unlikely to erupt?

Yellowstone is one of the most feared volcanoes on the planet and has the potential to unleash a huge explosion. But scientists analysing the potentially deadly super volcano say an eruption like that is extremely unlikely, and some previous studies have revealed the feared volcano is actually waning in power.

What causes a volcano to erupt violently?

When the molten rock or magma is thin and runny, gases can easily escape and the lava flows freely and travels far. An explosive volcanic eruption is caused by thick and sticky magma, which prevents gases from escaping and causes them to explode violently.

What should you do after a volcano eruption?

If outside at the time of eruption, seek shelter in a car or a building. If caught in volcanic ashfalls, wear a dust mask or use a handkerchief or cloth over your nose and mouth. Stay indoors as volcanic ash is a health hazard, especially if you have respiratory difficulties such as asthma or bronchitis.

Which supervolcano is most likely to erupt?

Mount St. Helens, located in Washington State, is the most active volcano in the Cascade Range , and it is the most likely of the contiguous U.S. volcanoes to erupt in the future. The volcano is almost 53 km (33 mi) due west of Mount Adams and approximately 80 km (50 mi) northeast of the Vancouver, Washington—Portland, Oregon metropolitan area.
