VEPP: Working with the VEPP website in an online M.Ed. course
This activity was selected for the On the Cutting Edge Reviewed Teaching Collection
This activity has received positive reviews in a peer review process involving five review categories. The five categories included in the process are
- Scientific Accuracy
- Alignment of Learning Goals, Activities, and Assessments
- Pedagogic Effectiveness
- Robustness (usability and dependability of all components)
- Completeness of the ActivitySheet web page

Students explore the VEPP website and complete a two-part problem set in which they work through the ideas presented in an EOS paper regarding eruptions at Kilauea and they try to find a deflation-inflation event using the VALVE3 software.
The content goals for this activity are as follows.
- know that volcanoes are monitored with a variety of instruments
- describe what happens to a volcanic vent in time and space during a deflation-inflation event
The higher order thinking skills goals for this activity are as follows.
- read a report detailing recent eruptive activity at Kilauea volcano.
- predict hypothetical instrument responses to certain volcanic activities
- calculate the rate of magma movement based on measured seismicity
- use the real-time volcano monitoring tools made available through the VEPP Web site to discover and describe an inflation-deflation event measured at Pu'u O'o.
Other skills goals for this activity include interacting with real-time data in a web-based environment.
Context for Use
I believe this activity could be used successfully either in an online or a face-to-face course and it could easily be adapted at the undergraduate level. Since it is a problem set and should be graded by hand, its use is probably restricted to smaller courses or courses in which there is a TA to assist with grading. Students need to have some facility reading a scientific paper, making simple calculations from time-series data, and navigating a web-based environment. Students need internet access to complete the portion of this activity that involves the VEPP website and the VALVE3 software interface.

Teaching Notes and Tips
Accessing the VEPP Web site (https://vepp.wr.usgs.gov) requires a password, which can be obtained by sending an email with your name, affiliation, and intended use of the site to mpoland "at" usgs.gov
The activity is self contained within the web pages I have designed. If adapting for a face-to-face course, background information about volcanic eruptions and the geology of Hawaii should be covered first. If using in an online course, you may want to have students read through the content presented in my entire week-long eruptions lesson to put the activity into context. Here is a direct link to page 1 of the lesson (the activity description and assignment are on pages 8 and 9 of this lesson): EARTH 520 volcanic eruptions lesson
