How long ago can a volcano have erupted, and still be considered active? Is
Vesuvius an active volcano?

Dear Alan,
Active implies that a volcano has erupted in historical time. So the
historic (written) record goes back a couple of thousand years in the
Mediterranean region and a couple of centuries in Hawaii.
Vesuvius is an active volcano. Have a look at question 7
in Volcanoes of Other Regions (6. Europe) in Ask a Volcanologist.
