  1. Using the Data of the EarthScope in Education Susan Eriksson, UNAVCO Director of Education and Outreach August 11, 2009

  2. Approach for today • Purpose • What types of data for EarthScope components • What will you use it for? • Resources for data • Resources for educational framework • Plan for after the workshop

  3. Why EarthScope? • Scientific discoveries - the ‘content’ • things we know • things we don’t know • How we go about ‘finding out’ • Skills of science -? • Exploration - inquiry

  4. Drillhole across San Andreas Fault 875 GPS Instruments 175 Borehole Strainmeters 5 Long-Baseline Laser Strainmeters 400 Seismometers at 2,000 sites 100 Permanent Seismometers

  5. SAFOD A borehole laboratory on the San Andreas fault studying the physics of earthquake nucleation at the depths where earthquakes begin

  6. Using Data in the Classroom

  7. US Transportable Array • Includes 400 Transportable Seismometers • Station occupies a site for 1½ - 2 years • 10 years to leap-frog array across the US

  8. Special Events 1.1.7 Special Events 2008 Wells, Nevada Earthquake Web fact sheet Teachable moment Powerpoint for faculty use Ground motion visualization: Blue down Red up  Charles Ammon, Penn State

  9. Community Products TA visualization from Chuck Ammon Uses Workshops Presentations Web Automatically generated version available from IRIS DMC Plans Matlab version Special events version for public and media Community Products

  10. PBO 11

  11. Plate Motion 12

  12. Using Data in the Classroom

  13. Cascadia

  14. Transient motion associated with faults Episodic Tremor and Slip Parkfield Earthquake 15

  15. Cascadia Interpretive Workshop Cascadia Subduction Zone We can see what’s on the surface. How does the surface change as a response to subduction? How does EarthScope help us appreciate earthquakes, tsunamis, and volcanic eruptions?

  16. Using Data in the Classroom

  17. Animations Developing series to explain EarthScope-related concepts Episodic tremor and slip Animations

  18. Animations Animations • Developing series to explain EarthScope-related concepts • Episodic tremor and slip
