Well, there is no definite answer. It depends on the definition of 'volcano'. For example, there are volcanic fields that hold many centers, but they share the same magma chamber, so they might not be able to be counted as one single volcano. During the past 10 thousand years, about 1500 volcanos have been know to be active on the land, but there is a larger number of those which are underwater. There are about 50 - 70 active volcanos currently (erupting nearly each year).
So there are many volcanos on the earth, a lot of them active, a lot of them inactive, a lot under the water (e.g. in oceans), and many that have not had any effect on human life, so they are unknown of. There have been approximately over a million volcanos during the life of the earth though.
