A Plinian Eruption is filled with gas, energy, ash, and very gassy magma which is deathly.

Type of Materials EjectedPlug 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.

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.

Describe The LavaThe lava in Plug Dome volcanoes is made up of

bulbous masses of lava.

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.

Impacts of EruptionNegative Impacts

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.

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.
