Although we are researchers first and foremost, we have a deep love for learning and teaching about the earth and earthquakes. So along the way, we have created some teaching tools that we use with students and adults who are not earth scientists. We invite you to use them as well.

		The 'Earthquake Machine' exhibits most of the observable characteristics of earthquakes, including stick-slip (long periods of strain buildup punctuated by sudden earthquake slip on faults); occasional foreshocks; and fault friction. This would make a great 'Science Fair' project.
		'The Science Explained' provides a series of online articles from magazines and newspapers written about our work in plain English, as well as the articles that we have written for the public.
		The computer 'Animations' can be played on the screen or can be downloaded for classroom presentations. Some explain how one earthquake can set up the next by the transfer of stress. Others show how buildings collapse in earthquakes and how they can be strengthened to resist earthquakes.
		The Northridge earthquake 'Slide set' tells the story of this destructive shock in several maps; they can be viewed, downloaded, or ordered from us as 35 mm slides free of charge.
		The 'Plate Tectonic Puzzle' introduces people to the most important and exciting unifying concept in the earth sciences today, in a way that's fun and scientifically accurate and up-to-date.
