How many active volcanoes are there in the world now?

There are about 1,500 potentially active volcanoes worldwide, aside from the continuous belts of volcanoes on the ocean floor at spreading centers like the Mid-Atlantic Ridge. About 500 of those 1,500 volcanoes have erupted in historical time.

What are the volcano parts?

The main parts of a volcano include the magma chamber, conduits, vents, craters and slopes. There are three types of volcanoes: cinder cones, stratovolcanoes and shield volcanoes.

  What is the bottom of the volcano called?
  
  In these cases, the lava vent is located at the bottom of the crater. They are formed during certain types of climactic eruptions, where the volcano’s magma chamber empties enough for the area above it to collapse, forming what is known as a caldera.
  
  Which is the most dangerous type of volcano?
  
  supervolcanoes
  Not surprisingly, supervolcanoes are the most dangerous type of volcano. Supervolcanoes are a fairly new idea in volcanology. The exact cause of supervolcano eruptions is still debated, however, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion.
