As recently as 1960, geologists asserted that the Earth was essentially static with a few volcanic areas, some post-glacial rebounding, and the final spasms of Early Cenozoic mountain building that produced small areas of uplift. By 1970, a new paradigm had blossomed from seeds sown as long ago as 1620.

A dynamic global system involving earthquake belts, massive fault systems, a 60,000 - mile-long mountain chain, and ocean floor trenches deep enough to swallow Mt. Everest have been documented. What will be California’s geologic fate? Is it possible that Yellowstone’s volcanic system will explode and destroy us all? Will the overdue magnetic reversal do us in? Why are there no earthquakes here and devastating ones there?

This course explores the unstable planet we call Earth.
