Mt. St. Helen’s Response

Identify and describe 3 ways humans have interacted with this volcano, including positive and negative interactions.
1. Scientists tracking and learning from the volcano. Constant watch and data analysis from the volcano. Learning volcano behavior, effects and even tracking estimations of when eruptions would happen. Using lasers, seismometers and more.
2. 51 deaths were recorded from the blast and the ash.
3. Nature came back. New growth has been created from the volcano. New fish can now be caught in the new lakes for fishing now.

Volcano Lab

When you watched your volcano erupt, what did you notice about the “pyroclastic” flow? Describe it’s movement.
1. Very Much Slow and nothing could stop its movement, bubbly and fizzy.
When you watched the videos of the Hawaiian Eruption from Mount Kilauea, what did you notice about the way it interacted with the landscape?
1. Just moved slowly across the land. Burned everything and a lot of things got engulfed in the lava.
Why is the volcanic activity important for places like Hawaii?
1. It is responsible for the islands themselves. Because of hotspots, lava flowing up from holes in the tectonic plates. The lava flows up to make volcanos and over time it layers and layers to make islands while the plates are moving.
How did people respond to the volcanic activity?
1. A lot just moved, a lot also stayed to watch it for some reason. There was nothing they could really do too. Many evacuations and people stayed to watch, take pictures etc.
Compare what you saw in the video to life here in Vancouver. What if the Coquitlam Mountain erupted, how would you respond?
1. My family I know for a fact would want to instantly move away, even if it doesn’t touch us. Because of all the possible ash and smoke, they would probably just drive away.

What went wrong with today’s lab? List all the variables that disturbed our results and create a solution to make the outcome more accurate.
1. Too many numbers and everyone had different numbers
2. Everyone has set data and so everyone has same calculations to do
Why do you need more than one seismometer station to find the epicentre of an earthquake? Why is one not enough?
1. To be more accurate, you can pinpoint where it is.
Why do you think identifying an epicentre location is important for our society?
1. So we can identify the location of earthquakes.
How could we use this data in an emergency response situation?
1. To find the areas greatly affected, for future earthquakes and for greater knowledge of those future earthquakes.
