The OIINK seismic experiment is the product of a collaborative research effort between Indiana University, Purdue University, the University of Illinois at Urbana-Champaign, and the Indiana and Illinois state geological surveys. The project seeks to apply state-of-the-art seismic monitoring and data analysis techniques to understand the deep geological structure and seismic activity in North America’s continental interior. The project will help us to better understand the basic geological processes that were involved in the assembly and evolution of our continent, as well as the processes that are continually modifying its structure. Ultimately, the research will help us better understand and better prepare for the hazards associated with future earthquakes in our region. The project is part of a national scientific initiative, dubbed "EarthScope" which includes the deployment of "USArray," the largest seismic network in the nation’s history.

The PEPP program has forged a new partnership among university-based academic researchers and middle and high school teachers and students. Research-quality seismographs are set up in physics and earth science classrooms, where middle and high school teachers and students collect, analyze and interpret scientific data. Teachers and students are given training in creating hypotheses, collecting and interpreting data, and how to present results, culminating in a weekend symposium where students and teachers gather at Indiana University’s Department of Earth and Atmospheric Sciences to present their year’s research.
