Project background
  • The plan
  • Software development and features
  • Where we’re headed
purpose
Purpose
  • To provide low-cost earthquake seismographs for use by volunteers in schools.
  • Expose students to geophysics and hands-on science early in their education.

slide6
MichSeis and PEPP programs are designed for permanent installations and dedicated staff
  • Teachers wanted a temporary seismic station
  • Needed user-friendly program
  • Grant from SEG made this possible
the plan
The Plan
  • Develop a user-friendly, interactive program
  • Use an extremely simple and portable system

A to D Converter

how do we do this
How do we do this?
  • Use the low-cost EAI S102 long-period seismograph
  • Use a Macintosh or PC with an inexpensive A to D converter
  • Write user-friendly interface with LabView software
what is labview
What is LabView?
  • Software that uses the iconic programming language G.

Night-time background noise level.

Data recorded prior to midnight (yesterday, in Universal Time) is shown in gray, indicating that it is nearly one day old.

Data recorded since midnight (Universal Time) is shown in yellow, in these four-hour blocks.

First, let’s look at a whole day of data.

Now that we’ve recorded an earthquake, we can look at it in different ways using the Viewer program:

the future
The Future
  • Test the program in Upper Peninsula schools
  • Train volunteers to work with their local schools
  • Provide one day training courses in conjunction with SEG, AAPG, AGU, IRIS, and other local societies
