Ready to dive into the world of earthquakes? Join us in exploring the Earthquake Machine and predict the movement of bricks on different surfaces. Understand fault slip and plate interactions in a hands-on activity. Contact David Steer for more information.

The Earthquake Machine What will happen when we turn the handle? Activity prepared by David Steer and David McConnell at The University of Akron, contact steer@uakron.edu (330)972-2099 with questions. Earthquake machine design from http://quake.usgs.gov/research/deformation/modeling/eqmodel.html .
The Earthquake Machine • What will happen when we turn the handle? • The tubing will stretch and . . . • the brick will move steadily forward • the brick will not move at all • the brick will initially not move, then jump forward
The Earthquake Machine What will happen if we place the brick on a surface covered in talcum powder? • The tubing will stretch and . . . • the brick will move steadily forward • the brick will initially not move, then jump forward • the brick will move forward in a series of smaller jumps
The Earthquake Machine Predict what will happen if we use two bricks instead of one. Will movement on the “fault” be more or less? • More • Less • The same
The Earthquake Machine Match these statements • Slip on a fault is represented by . . . • . . . the stretching of the tubing • . . . the movement of the brick • . . . the turning of the handle • The steady build up of stress due to interactions of the plates of lithosphere is similar to . . . • The deformation of rocks in the crust prior to the earthquake is similar to . . .
