Mt Saint Helens

Let's start by learning a little bit about Volcanoes!

  1. You are going to read about five different types of volcanoes. In your notebook, sketch each type, color it, and describe it in your own words (each description needs to include how the volcano type is formed and some information about its shape and size).
  2. Also check out four different types of lava. Sketch each type, color it, and describe it.
  3. Finally, read about the different types of eruptions. Now, in your notebook match every eruption type, to a lava type and to a volcano type.

Now let's find out what our most active volcano has been up to!

  1. Check out the live volcano cam and see what MSH looks like right now then click on the back button to return to this page when you are done, MSH VolcanoCam.
  2. Before you go on, check out these pictures.
  3. When you have read all these instructions, you will go to the following website:
    MSH Sept 2004 Eruption
  4. The above link will open a new window. Keep this window and that one open.
  5. At the above website you need to scroll through the page. It shows all that happened on September of 2004! At the top, left-hand corner of each page you will find a link to the next month.
    1. Choose one picture of the lava dome for each month and download it to your device or computer.
    2. Label each photo and title each photo so that you know which is which.
    3. Do ONLY the following months: Oct 2004, Dec 2004, Mar 2005, Aug 2005, Oct 2005, Mar 2006, June 2006, Sept 2006, May 2007, Oct 2007, May 2008, Oct 2008, Aug 2009.
  6. Read the captions and view the pictures while you create and a slideshow or animation of what happened to Mt Saint Helens since October 26, 2004. You'll get to see how the lava dome has change over time when you run your slideshow or animation!

 

Now check out some seismographic data!

  1. If you go to this website, MSH Webicorder Data, you will see seismograph data for Mt Saint Helens for Sept 2004. You can see what it looks like when it started erupting.
  2. If you visit this website, Volcano Seismicity, you can get earthquake information for all our Cascade Range Volcanoes!
  3. Visiting this website, Webicorder Site, you can see seismic data for our Cascade Range volcanoes!
  4. Here are webicorder files for Mt Saint Helens from Sept 2004 (the last time it erupted)! Webicorders are now called seismograms.
