The Seismic Ring: A Classroom Model for Mantle Seismic Wave Propogation
Abstract
We have built an experimental setup to simulate travel time calculations of seismic waves propagating through the Earth's mantle. Our Seismic Ring set-up consists of the following components.
Earth's mantle: An acrylic ring; Seismic wave source: A simple pendulum; Seismometer: Piezoelectric sensors attached to the outside of the ring; Seismic recording drum: An oscilloscope with flash memory; Computer: computer. This experiment allows us to make in-class comparisons between theoretically computed differential travel times and experimentally measured travel times from the Seismic Ring. At our poster, we will carry out demonstrations that illustrate how we acquire differential travel times in our device and how data stacking greatly improves the data quality.- Publication:
