An extinct volcano must have not erupted in historical times (when history was first recorded). It takes many many years to distinguish an extinct volcano from a dormant one, and it is very difficult too. An example would be the Fourpeaked Mountain in Alaska, which prior to September 2006, is not believed to have erupted since earlier than 7994 BC! Mostly, it takes about 5,000 to 6,000 years for a dormant volcano to be considered extinct, except in rare cases. Another would be the hotspot theory. Whenever a volcano island moves away from the hotspot, the magma source is cut off, and the volcano is considered extinct. An example would the Hawaii Chain Islands.

Is Lake Tahoe an extinct volcano?

The thunder comes before the lightning the lightning comes before the clouds The rain dries everything it touches?

This a riddle. It has been given as "My thunder comes before my lightning. My lightning comes before my rain. My rain dries everything it touches. What am I?"One suggestion is a volcano. It's roar comes before it spews out fiery magma, and possibly lightning occurs in the subsequent clouds above the volcano. Then it rains hot ash, which certainly dries everything it touches.


What is the definition of a volcano magma chamber?

A volcano magma chamber is a large underground reservoir that holds molten rock (magma). It is a key component of a volcano's plumbing system and acts as a storage unit for magma before it is eventually erupted to the surface. The magma chamber is typically located beneath the volcano and can vary in size and shape.

What is a volcano that does no longer erupt called?

the name given to volcanoes that can no longer erupt is "EXTINCTED VOLCANOES" (\___/) ( o , o) (\____/) ( >#<) ( o , o ) (") (") (^^^^^ ) ( O O ) ( 7 ) ( \___/ ) Of course it could also be a "dormant" volcano playing possum. It is difficult to distinguish an extinct volcano from a dormant (inactive) one. Volcanoes are often considered to be extinct if there are no written records of its activity. Nevertheless, volcanoes may remain dormant for a long period of time. For example, Yellowstone has a repose/recharge period of around 700 ka, and Toba of around 380 ka. Vesuvius was described by Roman writers as having been covered with gardens and vineyards before its famous eruption of AD 79, which destroyed the towns of Herculaneum and Pompeii. Before its catastrophic eruption of 1991, Pinatubo was an inconspicuous volcano, unknown to most people in the surrounding areas. Two other examples are the long-dormant Soufrière Hills volcano on the island of Montserrat, thought to be extinct before activity resumed in 1995 and Fourpeaked Mountain in Alaska, which, before its September 2006 eruption, had not erupted since before 8000 BC and had long been thought to be extinct.


Can volcanoes extinct?

No. If a volcano erupts then it is not extinct; during its period of inactivity it would have been dormant. To add to this. Two examples are the long-dormant Soufrière Hills volcano on the island of Montserrat, thought to be extinct before activity resumed in 1995 and Fourpeaked Mountain in Alaska, which, before its September 2006 eruption, had not erupted since before 8000 BC and had long been thought to be extinct. I am sure the odds are the same as winning the lottery every year for life.

What is a volcano that no longer erupts?

It is a dormant volcano. Or maybe an "extinct" volcano. It is difficult to distinguish an extinct volcano from a dormant (inactive) one. Volcanoes are often considered to be extinct if there are no written records of its activity. Nevertheless, volcanoes may remain dormant for a long period of time. For example, Yellowstone has a repose/recharge period of around 700 ka, and Toba of around 380 ka.[7] Vesuvius was described by Roman writers as having been covered with gardens and vineyards before its famous eruption of AD 79, which destroyed the towns of Herculaneum and Pompeii.
