It seems that the term extinct referred to volcanos is part of the popular
classification of volcanos.
Scientific classification has three: Active, Inactive and Potentially active.
Mauna Kea is loosing its juice because is moving away from the hot spot that
has created the Hawaiian Islands chain with the help of the tectonic movement
of the Pacific plate E-SE heading.
BTW: Fourpeaked volcano in Alaska woke up after 10.000 years of inactivity.
Some volcanos can have a span of two million years between eruptions.
Caveat reader: It is from Wikipedia...
