Some volcanoes are active, while others are dormant.
Dormant A+ :)
Mount Rainer has been dormant for 118 years. You get the answer by doing now 2012 subtracted - by when it last erupted 1894. -The Seventh Grader
Last erupted somewhere between 150,000 and 200,000 years ago
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.

HPV can lay dormant for decades before detection. A positive HPV test for cervical cancer screening gives no information about how long you've been infected.
Dormant volcano
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.
probably how big it is and hoe long its been dormant.

It's last eruption was in 1991 so it has been dormant ('asleep') for 20 years.

Depending on how long they've been inactive - they're called either dormant, or extinct.
