      • 3. The bulge eventually cracks creating vents for lava to escape through
      • 2. The pressure of the magma causes a circular bulge on the surface
      • 4. The lava erupts out of the vents causing earthquakes and sending up plumes of ash and rock
      • 1. Magma rises up through cracks in the crust
      • 5. As the magma basin empties, the bulge is no longer supported so it collapses
      • 6. When the eruption is complete, there is a huge crater (caldera) left.
