All About Volcanoes


What is a volcano

What is a Volcano?

  • A volcano is mountain that that leads to a pool of molten lava below the surface of the earth.

  • A volcano consists of a magma chamber, main vent, and a crater.


Different types of volcanoes

Different types of volcanoes.

  • There are four main types of volcanoes.

    • Cinder Cone Volcanoes

    • Composite Volcanoes

    • Shield Volcanoes

    • Lava Dome Volcanoes


Where are volcanoes located

Where are volcanoes located?

  • Most Volcanoes are located where two of earths plates collide.

  • Most volcanoes are located in the Pacific Ring of Fire.

    • Over 75% of the world’s active volcanoes are here.

    • Nearly 450 volcanoes in a


What causes a volcano to erupt

What causes a volcano to erupt?

  • The earth’s core is extremely hot and it heats the magma.

  • When the magma gets really hot it begins to bubble.

  • This bubbling creates carbon dioxide gas that expands.

  • The expanding carbon dioxide gas creates pressure and pushes the magma up the vent of the volcano, causing an eruption.


Famous volcanoes

Famous volcanoes

  • Mount St. Helens, Washington.

    • Still active volcano that is famous for its eruption on May 18, 1980.

    • Most deadliest and destructive volcano in US history.

      • 57 people died

      • 250 homes destroyed

      • 185 miles of highway destroyed

  • Krakatoa, Indonesia.

    • Erupted on May 27,1883.

    • Explosion was the loudest sound recorded in history.

    • Eruption generated a tsunami.

      • 36,417 people died

      • 164 villages destroyed

      • Thousands injured

      • 2/3rds of the island was destroyed


Impacts effects and damages caused by volcanoes

Impacts, effects, and damages caused by volcanoes

  • Results in hazards such as:

    • Pyroclastic flows- quickly moving gas, ash, and volcanic rocks that can kill people if they are caught in them.

    • Volcanic ashes- are like small sharp glass particles that can cut off the oxygen supply.

    • Lahars- mudflows from mixing ash and water that can carry large boulders and logs. It can topple and cover buildings and can result in crushing or drowning fatalities.

    • Lava flows- quickly moving and very destructive since they burn and bury everything they come in contact with.

  • Volcanoes can cause:

    • Landslides

    • Floods

    • Tsunamis

  • Loss of life

  • Destroys homes, communities, businesses, and the landscape

  • Economic decline

  • Destroys highways

  • Destroys bridges


  • Safety measures when volcanoes erupt

    Safety measures when volcanoes erupt

    • Follow evacuation orders and warnings.

    • Learn about community warning systems and evacuation plans.

    • Avoid low lying areas.

    • Seek shelter inside.

    • Close windows.

    • Prepare disaster kit that includes:

      • Breathing mask

      • Goggles

      • Evacuation supplies

    • Wear long sleeve shirts and pants.

    • Keep mouth and eyes covered.

    • Turn off car or truck engines if caught outside.
