Week of January 13th 

Volcanoes - Continued!

December 2013 - Mount Etna erupts in Italy

December 2013 - Mount Sinabung erupts in Indonesia 

December 2013 - Mount Chaparrastique in El Salvador Erupts


Questions of the Week:


1.  What do all 3 of these volcanoes have in common? 

 Explain each of the following topics as they relate to these 3 active volcanoes: 
  • Plate tectonics 
  • Type of volcano
  • Eruption behavior
  • The safety of living near these volcanoes
(Record your answers after p. 237 in your workbooks)


Iceland's Hekla Volcano erupting in 2012 - notice the aurora?


Question:



 2.  How are the 30 volcanoes in Iceland different than the 3 volcanoes above?

    all three of the volcanoes on the blog are composite volcanoes,The safety of living near these composite volcanoes is very small because of all the pyroclastic material killing everything in its path.This tectonic plate would be a convergent boundary since they are so tall.Since convergent boundaries capture high concentration of fluids and force magma to rise this would make the volcano erupt frequently with chunks of rocks and whatever amount of magma that rises with the pressure.

    In the pictures of the volcanoes above, they are all surrounded by some form of active human environments, so if they exploded it would be very dangerous, but in Iceland it is different, but still dangerous.

    How are these volcanoes alike?
    Plate tectonics: Convergent
    Type of Volcano: Composite
    Eruption Behavior: Explosive
    The safety of living near these volcanoes: Really nothing because you never know when this deadly volcano is going to explode. Also, once it bursts it destroys everything in its path. The Sinabung danger zone is a radius of 10 km from 5-7 km currently. Also, Sinabung has erupted 220 times this week.
    How are the 30 volcanoes in Iceland different than the 3 volcanoes shown above?
    The 30 volcanoes in Iceland are divergent while the other three volcanoes are on convergent plate boundaries.

    Mount Sinabung- Tessa Doan

    What type?- Composite, Stratovolcano

    Where is it located/Plate Boundaries?- It is located in Indonesia, where the African and Eurasian tectonic plates meet. It is located in the Ring of Fire.

    Eruption Behavior: This volcano, when it erupts, creates lots of ash that fills the air. Lava also comes out of Mount Sinabung with high viscosity; which makes it very slow moving and thick. In its eruption in 2013, 77 eruptions occurred in one day. It averaged about 22 eruptions in twelve hours. 22,000 people have been evacuated for an eruption.

    Safety living near Mount Sinabung: When there is an eruption, or one might occur, evacuations take place. Many people leave their home and whatever else they have (farms, crops, etc.) and get as far away from the volcano as possible. People within a one-two mile radius are first evacuated, then, if needed, others farther than that distance are supposed to leave as well.

    They are all composite volcanoes and they have all erupted latley.

    2. How are the 30 volcanoes in Iceland different than the 3 volcanoes above?

    They are at convergent boundarys and the 3 above are divergent.

    All three volcanos are alike because they all have a convergent plate boundary, composite volcano type, and very explosive. Living by one if these volcanos is very dangerous because they are very unpredictable. Also the lava is very harmful once the volcano explodes it ruins everything in it's path. I researched mt. Sinabung, it erupted 220 times in a week and displaced more than 220000 people.
    The main difference between the tree volcanos above and the ones in Iceland is that the volcanos above are convergent and the Iceland volcanos are divergent.
