  2. Famous Plug Domes • Novarupta Dome – Elevation – 841 m • Mount Pelee – Elevation - 1,397 meters • Lassen Peak – Elevation - 3,189 meters • Black Butte – Elevation - 1,962 meters

  3. Novarupta Dome

  4. Mount Pelee

  5. Lassen Peak

  6. Black Butte

  7. Type of Eruption Plug Dome Volcanoes have a A Plinian Eruption is filled with gas, energy, ash, and very gassy magma which is deathly. Plinian Eruption.

  8. Average Height The average height of a Plug Dome Volcano is: less than one thousand feet.

  9. Outline of a Plug Dome Volcano

  10. Type of Materials Ejected Plug Dome volcanoes spill loose fragments, (parts of the volcano) down its sides. Some domes form craggy knobs or spines over the volcanic vent, while others form short steep-sided lava flows known as “coulees.” Example on next slide.

  11. This is an example of lave flowing down the steep sides of the volcano, even though it is difficult to see the volcano, you can still get the idea of the lava flowing.

  12. Describe The Lava The lava in Plug Dome volcanoes is made up of bulbous masses of lava.

  13. Where are Plug Dome Volcanoes commonly found? Plug Dome volcanoes are commonly found in California and Alaska. Most of the famous ones can be found in Lassen Volcanic Park on Medicine Lake Highland.

  14. Impacts of Eruption Negative Impacts Positive Impacts The positive impact of a Plug Dome eruption is the fact that it forms glass, and also pumice. Pumice is very valuable to most people. The negative impact of Plug Domes erupting is the population dropping. The population drops because of the ash, gas, and dust that is exposed when the volcano erupts.
